A problem going from the top of the plant to the bottom would most likely rule out pH probs and roots getting light. You also have your temps around 60 so the heat from the light would be a good thing if anything. My guess without looking more into it is the Mag def. Goodluck <3

Also I'm going off logic here not by facts.
Da1KrayzieThug Reviewed by Da1KrayzieThug on . more problem pics. ok folks, these pics are of my train wreck plant with leaf curling. so far ive got four answers for this problem. 1- heat from lite. 2- PH problem. 3-magnesium defishontcy. 4-roots exposed to lite. i am very thankfull for all replys. but who is right? the problem started at the top of the plant and spreading downward,also spreading to new growth :confused: thanks again.
