3rd Grow- Same issue..

[Weouthere]

Hey guys! Thanks for reading. Got 1/2lb from my last grow!!

I’ve got 6 plants running right now. 4 thin mints, gelato, and gelato dosido. A different soil mix this time, 2:1 ratio of FFOF and Mother Earth coco-peat. So far they’ve only gotten water, and I’d like to try and keep it that way.

Ive noticed some interveinal chlorosis happening on this grow and my last one. Is it a soil problem or is it my light? I’ve never read about LEDs doing this so I doubt it’s that, but It is a wonderment I have. Should I be giving nutrients? I need to transplant the 4 small ones; doing that later tonight. I could add more ffof on top? They get kelp extract at transplant.
sorry for the ramble; but any help is appreciated. Much love and happy growing

I also noticed some crinkling on the leaves. Is that a heat problem?

they might be too young for fox farm, even at 2:1. don't give any more kelp if you have already. really shouldn't be necessary. just because you can buy doesn't really mean plants need it. looks like you have dark green leaves, which is one reason why they're too young for fox farm. just water when dry and transplant when you feel you should, but make sure they are established enough, then just go with only fox farm soil. make sure you don't over water. the soil should get pretty dry to allow oxygen in to the root zone, only then do you water. if you feel like it's too hot in the space or the light puts too much heat on the leaves, then it's probably too warm. use a fan and raise the light if necessary. Ideal indoor temp is 75F or less.

Just got another fan today, but I have two 6” in there now. Tent runs about 81-84f, but I run led and have read that is a good temp for the stomata.

They were planted in this same mix on 7-15, so I don’t think it’s too much for them. They’re a pretty green color in person. I fimmed them not too long ago.
I only give the kelp at transplant. It has helped with shock and root development.

Can you rule out bugs? Whats all that debris on the leaves. What haven't you changed in the last 3 grows for this to happen 3 times

Hey man I just saw this reply.. not getting notifications for some reason.
Anyway- my first grow was straight ffof/water, 2x2 box, HLG 100.

2nd grow was in a 4x4 tent, meijiu 480w board, 50/50 ffof/happy frog.

3rd grow now, 4x4 tent, meijiu board 50/50 ffof/Mother Earth coco peat.

So LED lighting would be the only thing I can think of that I’ve kept the same.
