Hello guys. I finished my new growbox and one plant is in. Its been there for almost a Month now. Since I had a holiday and didnt have time for aby new plants, I decided to move 120cm big plant from my friend from outdoor to indoor (she was in the pot Since seed) I transfered it to the new bigger pot (30L of new fertilised soil from Gold label) and put it in the box.
Temperature: 24-27 Day. 20-22 at night.
Humidity: 55 Day. UP to 70 at night.
Light: my solstrip Light 3500K. I curently run on 190w, 30cm Above the plant.
I put her on 18/6 cycle but I discovered, she is already induced flower so I changed the cycle to 12/12 six days later.
The pot is quiet big now so the watering is done every 6 days or so. I started with EC 0.6 and pH 6,2 and 2 days ago a watered with pH 6,4 and EC 1,1.
The problem is that when I got her, she was Very dry and underfed. So I thoth that the new soil and EC 1.0 will be enough but is it possible that its still not enough?? Because the plant looks really great but yellow leafs are more and more all over the tops of the plant on biggest leafs.
Looks like possible magnesium deficiency… possibly add some epsom salt. At least that’s my indication with how the leaf isn’t fully yellowing, merely between the veins, while the veins stay dark green. Judging by reading the Gold label website, it looks like their substrate soil has 2-3 weeks of feed in it, so you’re going to have to add in more after it runs out.
Yeh i’d say it’s hungry. I noticed plants seem to get through nutes (especially magnesium) really fast when growing under Solstrips. If you match nutrient uptake the growth rate is astonishing in coco
Also some bloom nutrients might not contain enough Nitrogen at normal doses
You could try a foliar spray of Epsom salts too. Google will get you a recipe. Careful to not overwater - I do not see a whole lot of perlite in your soil. Overwatering may look like all sorts of deficiencies because it eventually causes them. Also pH of 6-6.2 is probably a little better.
In flower in dirt, when the soil is depleted, I have fed as high as ec1.9 and had no nute burn, so assuming everything else is a-ok, they look like they are hungry

EDIT:
I just noticed that older growth is not uniformly affected, so this is likely a semi-mobile deficiency. Sulfur? Either way, Epsom salts, foliar, would be my first shot at it.
Does anyone think it might a typical fade from being outdoors? I have a few outdoors now that are showing this also if it was outdoors depending on location, flowering started about the first week and a half of Aug! That makes it about wk 7 of flower now
Maybe…? The flowers are not well developed though, usually they would be a 'lil further along before she fades, no? And the fade of newer growth seems to be further along than that of older growth, would that be the case with outdoor? I don’t know…
I have to admit my outdoor kung-fu is not very good. I replied based on what I’d think of her indoors, so you might very well be right!
It might be that the transplant into the new pot, along with the ~week of 18/6 lighting may have caused a bit of a stutter in her development. The color is all over the place, but she seems fairly healthy overall
OK guys. I am prety suer that she is hungry, so I will raise the EC on 1,5 next watering. I am aslo growing in smartpot so not enough oxygen shouldn be a problem. I also let the plant dryout before watering
But the next problem is here. SPIDERMITES! I jsut found a few on the back of the damaged leaves. small bugs with webs…So I order the Phytoseiulus persimilis to eat them out I cant apply any spray because of the buds in progres…Or can I??
Thanks I just discovered, that I cant order any parasittes, becaouse the season is over I will clean my kitchen and try to do the spray you posted. I got a lot of cilantro, mint and rosmary in my freezer
Edit:
they mention that you need to ad and aloe very (“Add the appropriate amount of aloe vera because you definitely want Salicylic acid in this mix as explained in the book I sent you about this hormone.”)
I use aloe a ton. Fresh is best, but messy and a pain in the ass. I can get the filets at Sprouts. Cut it in half and scrape out the pulp and gel, then hit it with the blender. Add 1/4 cup of this per gallon. I can get about 1 cup from one of the filets, costs $2.
Hi guys. The plant seems Just Fine right now. I fed her a lot and she is finishing flower.
But I might have a problem with the new ones. I am not sure. They are 15 days old now since seed. I feed then with advanced nutrients and I use their feeding chart. I watered them Last thursday so 8 days ago with second week feeding with EC 1200. They are in Coco and still prety wet since then. They Just dont want to dry out…So I am a bit scared that I might over water them. So I m waiting and waiting to dry out and I Think that they are Just hungry. What do you Think? Should I feed them with max feeding now or third week feeding? Thanks!
can we get some close up of the bottom set of seedlings… from that angle they look like either you have pest damage or necrosis, both aren’t ideal but can be fixed…
I’m leaning more towards necrosis since you said they were still soaked… let them dry out because over watering will destroy a plant too
the ones up top are looking good… May have a cal/mag issue starting up, but it’s not showing to heavy yet.
The affected leaves are young, it is chlorosis (yellowing), it is interveinal or blotchy which suggests zinc, manganese, iron or copper.
IMO If your PH is right then they just need a feed. They are not overgreen so some N would not go amiss.
EC 1200? I think either you have mixed up your units or not put a required decimal point.
I would say an EC of 1.2 would be about right, a PPM of 1200 would be too strong and you would see better results from a weaker, more regular feed.
EDIT :
Also, try to bring the temperature down and the humidity up. At 31C and 47% they will start to close their stomata, which may explain why they are not pulling up as much nutrients or water as they could.
You may find that if you lower your temps and raise your humidity that your nutrient deficiency goes away as if by magic…
But this is the overall problem! ok, I will bring my temperature Down, so I set my fan to max and I will put FRESH air to the tent but then my humidity will drop to about 40% because thats the humidity in my room. So how do I do that? I have to choose between one or another? I really hate this!
Generally people get some form of ultrasonic mister/humidifier or make some other method of putting moisture into the air until their plants are large enough to keep the space humid.
Cool dry air is better than hot dry air.
You could always google ‘swamp cooler’ which will cool your air and raise the humidity at the same time. It is basically a tray filled with water that has a fan blowing on to it. the water evaporates, raising your humidity and cooling the air.
I will clean my kitchen and try to do the spray you posted. I got a lot of cilantro, mint and rosmary in my freezer
