I wouldn’t worry to much that’s pretty normal for the bottom leaves to go yellow. But still keep an eye on ur ph and make sure ur not giving to much nutrients or to little!! Other than that it looks pretty good to me!!! Happy growing bro!!

I feed them very little bio grow only once..can it still be nitrogen toxicity?

Bottom leaves are dying off due to lack of light. Most trim them off. I doubt it is nitrogen deficiency, your plants looks closer to nitrogen toxicity. Would be my diagnosis of it. Good luck and happy growing 🌱

Yellowing, curling tips?I'm in the middle of week seven and noticing significant yellowing, curling tips, especially on the top colas. Is this cause for concern and what could be causing? Feeding low-dose (1/4-1/2 tspn/gal) of dyna-gro bloom and the plant is growing in MG soil. I know, rookie mistakea year ago

Yellow spots on bottom leaves.Starting to notice big brown/yellow spots on the bottom leaves only. Plants look healthy at the top but not happy(not praying and look droopy). I water every 3/4 days so it’s not a matter of being locked and Calmag is also used. Can’t figure out what the problem is here.Leaves. Curl down

Slight leaf tip "burn"What do you think is causing this burn on my leaves? It seems to be quite common. and maybe nothing to worry about if it's this minute. but I would prefer to not burn my plants at all if possible. Could it be a sign of underwatering? Light distance? i have a dimmer keepin at 1000a year ago
