Nutrient lockout?
Mark3RocketSpecialstarted grow question 4 years ago
Having a problem with bottom leaves turning yellow and dying. Starts off with brown on edges and tip, then leaf yellows and dries up. Potassium deficiency? PH problem? I flushed plants yesterday with 6.5 ph water and sledgehammer flush from fox farm. Pictures on week 10. Thanks!

I would say looks more like phosphorus deficiency. I would get rid of them small leaves around the bottom of your plant as they are not getting enough light and aren't really going to add much to the grow. I have looked and you don't mention what nutrients or media your growing in. But you should be on the bloom phase of a nutrient program by now.

Seedlings - Over-watering?Hello all, I just started my first grow. I was thinking I may have exposed the seedlings to excess humidity (90% in cloning chamber)causing the cotyledon to curl down on one side. Wanted to get some feedback if my assumption is correct as the soil looks and feels quite dry.Leaves. Curl down
