@FieldEffect Maybe try out “JADAM” sulfur. I hope I didn’t already mention that. It’s a way of making water soluble sulfur out of plain old “sulfur powder / wettable sulfur / powdered garden sulfur”. You just need the sulfur powder (high purity, like 98%+ I think), and sodium hydroxide (“lye”).
The chemical reaction “melts” the sulfur and you end up with a liquid concentrate that can be added to water (diluted) and sprayed or applied however you choose. Same benefits as sulfur, way easier to use, and likely much more effective. (There’s also a JADAM wetting agent that goes along with many of their recipes, and also uses sodium hydroxide in its production). https://www.youtube.com/results?search_query=jadam+sulfur
Another member here also mentioned he sprayed his outdoor plants with HOCl (hypochlorous acid) for powdery mildew. I was already reading about it, and so I went and bought an HOCl generator (the NatureChlor). It works by electrolysis; low voltage + NaCl + acetic acid + time = hypochlorous acid. I’ve been using the stuff heavily now, just because I can, it’s cheap to make, and it’s incredibly safe when compared to, say, bleach (hypochlorite, I think). It’s commonly and widely used in many applications, eg: hospitals, dentist offices, etc.
That reminds me, I need to ask houseofhydro if I could use HOCl in a diy atomizer/humidifier to sterilize, because bleach ruins them.
with the Fish Hydrolysate being an infrequent / bi-weekly application, that may be a nice way to give them something to chew on @FieldEffect. They ALL LOOK BLOODY AMAZING
Thanks for the compliments guys! It’s appreciated almost as much as the help that has gotten the plants looking like they do. I’ve learned a LOT this summer.
@noknees pics attached. She’s not as yellow today, the EWC may be kicking in. I’ll post at the other resource as well
@MissinBissin I’ve been cutting back on the hydrolysate going into flower because people say it makes the bud taste like fish. I don’t necessarily believe that, but I’ve been easing up on that going into flower. I haven’t tracked amendments as well this year (I did but it’s hard to find all the posts and have a concise summary anymore). I need to retain my simple text file with dates and what I added so I can keep tabs on how much total product I use. I will say my second gallon is halfway gone
@Ottafish K, huh? Interesting. I’ve never seen yellowing like this attributed to that. I also have really high levels of K but they are mostly bound. Here’s a leaf to see what a typical fallen one looks like
@Nitt the JADAM sulfur is something I’ll read about. I’ve definitely seen people using it here, seems like a PM thing I never really thought about the insecticidal properties. Off to read. Is it useable in flower? Does it work on grasshoppers?
@Coda my username for this and other sites are puns on transistor junctions. N-channel is your favorite because it’s objectively the best Glad some folks recognize it
Cheers boys here’s the girls after the storm, standing strong
That’s exactly what happened. I’m holding the phone up over my head pointing down. The other pic is phone over head looking up. She’s out of control
Good to know about the fish, I’m loving that stuff
@Ottafish can you point me somewhere to read about that? I’ve been referencing the Jorge Cervantes chart mostly EDIT: didn’t notice your post above on my phone, checking it out now
Here’s another. Your plants look more like it’s nitrogen though. Yellowing from the bottom up. If I remember right I believe potassium deficiency the whole plant yellows at the same time. Could be both too? Well actually they look pretty damn good. A few yellow leaves is normal. Your plants are budding pretty good sucking the nutrients out of the leaves.
I’ve not seen/heard anybody using it here. As far as I can remember, there’s several “pests” that do not like it, along with fungus/mildew and that kind of disease. I don’t know about grasshoppers.
I’ve never made the JADAM stuff. I would’ve tried but can’t source a small amount of sodium hydroxide affordably. I’ve used the powder just “suspended” in water with some surfactant, as most people do. But I don’t spray anything in flower, or even much in veg really. Though I’ve been spraying HOCl in the air and in front of fans, and on the bottoms of my shoes, on my hands, on clones etc. I got some clones from someone (first time ever, couldn’t trust “outside” plants. I hate bugs.) recently, and I sprayed them completely, roots and all, until they were basically soaking. I quarantined them in a large tote, sprayed them heavily with wettable sulfur, then and misted them with HOCl occasionally.
Thehypochlorouscompany is one spot, controlomatic is the company that makes the generator that I bought.
JADAM has an official website, I think. And KNF (korean natural farming) might have some cool, and useful stuff that you outdoor gardeners could take advantage of. Really good stuff.
I think I’m close to dialing in an elemental sulfur and pyrethrins mix but obviously can’t be used in flower. I’m too dumb to try the JADAM but you smart folks should definitely give it a go.
Don’t want to bring any bad energy just before adjusting feeding id look them over real good for round spots with grey in the middle on the leaves.
Thanks @Nitt! I listened to YouTube videos about it on the way to work. Wish I could get a small bottle to try rather than make 10L of it to use at 100:1 dilution ratio. Certainly seems interesting, I’m going to order the JADAM books. Probably lots to absorb in there, and people have very high opinions on the content. What I haven’t discovered is really what the cons are to using it. More digging tonight HOCl is another rabbit hole to dive down I’ve only seen mentioned but haven’t taken much notice of. Yet.
@shade it sounds pretty easy. Most of the videos on the subject are videos of it being made. But I don’t know much about it yet. Sulfur and pyrethrin sounds like a good idea for insects, how’s that working?
Do you see something I don’t? Septoria? I know it can make yellow leaves but I figured the uniformity of yellowing (haven’t noticed spots but haven’t looked for them either) pretty clearly pointed to being a little hungry for N. I’m probably just being meticulous but I’ve made it this far trying to keep em happy all the way to chop day. I’ll examine them looking for spots or indication of K deficiency (thanks for the pointer @Ottafish).
@MissinBissin hopefully each year I keep making these steps forward in the garden. It’s sure been some strides this year. Appreciate all the support, help, banter and cheering on
Septoria was what I was thinking, you seem much less at risk but I remembered that clone that died came from the same source mine that had/got it did. For me it happened with those dropping leaves then some dots then variegation then it looked fine but stopped feeding and maturing. Like I said just keep an eye it’s probably not that.
I see nothing wrong with your plants at all. It’s natural for the leaves to start senescence starting with the older leaves first. They may be a little hungry, but I wouldn’t get paranoid about it. I don’t see any sign of Septoria. As you probably already know, Septoria is really easy to spot. It always has brown/black circles with a yellow halo around them:
Anecdote from my recent experience with it.
I have bags of various organic products from when I made an order from kelp4less years ago. I grow synthetic though. A few weeks ago, I got the itch to use something in addition, just in one res (20gallon). You know how it is, when you have bottles/bags of stuff you don’t use; you wanna use them. So I added some fulvic acid powder, and amino acid powder (I think that’s all) to my new res batch. Several days after, I noticed some of that “clear” floating stuff in the res that appeared to be some bio film or something. Possibly it started to build up in the black tubing that leads to my “8 way irrigation heads”, and when the pump turns off, it flushes back into the res through the pump. Though it could have additionally built up in the res itself maybe.
Anyway, I started adding hypochlorous acid to the res, pretty nonchalantly - just eyeing it. Pouring from my spray bottle into the res. I don’t have any info on amount or frequency, unfortunately. But anyway, I just kept things going as usual (irrigation wise) and was adding this stuff for a while, and when the res got to the last liter or so, if there was any “stuff” floating in the solution, I would just throw that last little bit away. But before that point the pump was definitely sending bits of the floaty crap through the various irrigation tubing.
It might have been a week in total, maybe less though, and then the bio film was just gone. Not a trace remaining, and hasn’t returned since even though I haven’t been putting more HOCl in the res. No more occurrences in the res, none on pumps/pump cord, tubing, nothing. No visible negative effect on the plants (ie: nothing I can tell). This was in maybe week…5 or 6 maybe. First time with this variety, first time sealed room/co2, and new light, but the only issue I’ve had so far is the same one I often have that looks like a potassium deficiency (duno what from exactly). Some of the largest top colas I’ve grown, personally. Not attributing that to anything in particular though, just saying.
I always fully disassemble my water pumps (after seeing what builds up in them even if you rinse them and spray through their internal after every single use about 6-12 months ago). Now I remove any of those stupid back “covers” and unnecessary “bases” from pumps as well. And now I spray practically everything with HOCl, because why not? It’s so cheap, haha.
Anyways, I’m babbling now. Sorry for the long winded post.
Yup, you’ve got a ‘beautiful’ case of Alternaria. It usually starts in the lower foliage and randomly spreads up the plant. It will defoliate your plants given enough time…
Hypochlorous acid will organically and effectively control THIS DISEASE.
Glad some folks recognize it 
HOCl is another rabbit hole to dive down I’ve only seen mentioned but haven’t taken much notice of. Yet.
