Why are my plants leaves so bright green/yellow?

OrganicCannabisConnoisseurstarted grow question 6y ago

Wondering if anyone knows why the plants might be looking as light green as they are? We are running a purely organic grow and have not added nutrients beyond the super soil mixture. Wondering if anyone has any tips or suggestions, thanks!

I'll be honest and say they look healthy to me. A picture under natural light may have given a better idea. Purple lights tend to hide problems in pictures. If you feel their colour is a little light,she is probably hungry. Happy growing ✌️

Too much P and K seems most likely as the top growth looks mostly affected.

It could be several things. First, it might be nothing-it's hard for me to see from the pic, but new growth is often light green. Second, have you changed your lighting at all? Moving a light closer or installing a higher intensity light could be giving them some light burn, this commonly affects the leaves closest to the light first. Lastly, it could be a cal/mag issue. I would try giving them a dose of calmag and see if they begin to improve. You could also make a foliar spray of epsom salts to see if it is just magnesium causing it. Good luck!!

Possible deficiency/humidity/pH problem I've been struggling with same problem from beginning of grow - leaves having these dry yellow/white spots. The first week I used too high pH which later I replaced by rainwater - new leaves were healthy, but last night I left tent at 70% RH. Somehow it returned - still rainwater

What's the problem?Hi guys, basically for the last few days the problem hasn't varied too much but I can't figure out if it's my light or if it's coming from somewhere else. Some of my leaves are curling with stains either on the leaf or like a burn on the tips.
