Yep. Mix of burn and deficiencies the new MegaCrop formula is doing this to a bunch of us and it’s annoying as fuck. All the plants have it I’m just going to defoliate the bad stuff that could cause mold and try to get em through to finish without killing em. I reckon theres only 3-4 weeks left on them anyway but it’s still stressful dealing with underfeed issues outside and overfeed issues inside.

So the outdoor plants seem to be responding well to the DNF and Monster Bloom. Back to praying tonight and already seem to be darkening back up. So I upped the dose again tonight to 2.2ec DNF Gro and .3ec Monster Bloom.
Might consider using this on my indoor plants if they keep looking good like this.

I’ve been seeing some similar orange spots on a jungle spice mother that I’ve had in a solo cup for months now. I’ve been hitting it with full veg strength mega crop (1000ppm) yet they continue, so I decided to check the runoff ppm (something I never do). Turns out runoff was over 1200, so salts have been building up in there like crazy. I ran a ton of water through then saturated with veg strength again, I’ll report back if it helps.
I think mega crop is pretty ‘salty’ and seems to build up over time. The overabundance of nutes probably led to some kind of lockout…

@beacher Yeah I’m noticing that as well. PPM spikes from 900 going in to 1300 coming out I’ve been giving them straight tap water but it’s not going down another flush might be in order but I’m tempted to try to finish them on these DNF veg nutes + PK booster instead of MegaCrop because I had a peek in there earlier and wow, these plants look dying to me.

Ya my budding plants got burned pretty badly, my own fault I was lazy and didn’t catch it in time. Runoff from some was as high as 3000ppm…WTF lol.
Not gonna give up on the MC yet as it worked pretty great last time. I’ve learned a few things, flush regularly and don’t feed so damn high. I’ll keep a much closer eye on in and out ppm next round to try and find a sweet spot.
In the past I’ve used all nutes at like 80% of what they recommend max, I’ve been pumping up the MC thinking it’s ‘organic’, but salts are salts I guess

I tried flushing and decreasing to 1.4EC but then my plants started dropping leaves from low N.
Tried upping to 2.0EC but that made things worse. I brought it back down to the 1.7EC which is recommended on the package but the problem is still getting worse and buildup is still happening almost overnight from a full flush.

I’ve been having great results on all veg plants at 1.2grams per liter (~1000ppm on my crappy meter) and ~6.0ph. Pretty much perfect really. I think I’ll stick with that along with biweekly flushes, and will probably stick around that level for flowering as well.
I’ve got 20lbs of this stuff, no way I’m giving up on it yet lol. Also I have to say it does me better than canna that I used the last few rounds.

That’s crazy that you can run that high with the new formula. I find anything over 850ppm causes issues with this stuff.

Well ppm meters are all different, and mines a cheapo so who knows really.

So I just checked runoff, it was 2.6EC, decided to flush em down to 1.5EC tonight and see how they look tomorrow and decide if I wanna run these DNF nutes instead.

So I checked the runoff on the “best” looking plant. It’s super high, like 4.4EC
The worst looking plant had a more reasonable 2.6EC runoff
Could it just be, through a series of coincidences, that I was really misinterpreting this as an overfeeding issue when in fact I’ve been underfeeding them? And by all this flushing I’m doing am I making things worse?
So confused. Going to see if they take a bad turn tonight after this flush and if so I’m going to assume I need to increase the MegaCrop dosage to something higher.
Also going to go in and clean up some of the foliage tomorrow. It’s jam packed and while I swore I was going to chill out on the defoliation, I want to err on the side of caution and what I know works so I’ll take off any badly affected leaves and open things up for some airflow. We don’t want a repeat of last round!
Also note to self that these are 52 days old. I don’t know how I got mixed up on their start dates. Hopefully they’ll finish up quickly so we can reset. I’ll have to start some more seeds soon.

I hate being in that position, I usually start with the basics, and check the root zone ph to make sure that’s not causing bad shit to happen and then go from there, but as they are all looking sorry for themselves, it’s probably the food being, too much or too little like you suspect.
I have never checked run off, probably because it’s not often I get any lol.

Well today they were dropping yellow leaves left and right. So it’s obvious I need to increase feed. Gonna try ~2.1ec and see what happens.
In the meantime I did some defoliation of some of the worst stuff.

Just fed them, ended up closer to 2.4EC, will see how that goes.

Megacrop isn’t organic

They claim it is except for the cal/mag marshmallows, no?
Also note the sarcastic quotes around ‘organic’. I don’t really consider it to be either, but its close enough for me lol

It’s close, but no cigar. lol

Dont wanna burst your bubble, But, Looks like they have been either overfed, or a possible calmag issue… Ill bet the leaves are crispy and dry. Cal/mag deficient plants look “Rusty”… This kind of stuff can happen from “overwatering” as well … Which can/will leach out nutrients.
calmag deficient leaf

Probably not overwatering as I run in coco coir and water to a healthy runoff everytime and they dry out between watering cycles. And yeah they are very crispy.
I think its cal/mg deficient. Gonna grab some epsom salts tomorrow to start adding in.

Epsom salt only contains magnesium and sulfur. If i were you, I would be using a calmag supplement @ 2-5 ml per gallon, especially in coco fiber.
Cal-Mag® Plus is a specialized calcium, magnesium & iron, plant supplement designed to compensate for deficiencies in some commercial and hydroponic nutrient programs. Cal-Mag Plus also compensates for the natural calcium draw of coco coir fiber.
Cal-Mag® Plus provides a precise balance and optimal ratios of the calcium, magnesium, and iron that are critical throughout all stages of growth, especially in heavily fruiting plants and fast blooming annuals. Cal-Mag Plus is fortified with a proprietary blend of select trace minerals to help maximize yields in fruiting and flowering plant varieties, prevent blossom end rot in tomatoes and peppers, and reduce tip burn in lettuce. When used in combination with nutrient solutions Cal-Mag Plus functions as a catalyst to increase the uptake of essential minerals.
