I was wondering if anyone knows whats wrong. The leaves on a few get brown spots on them, curl up and then dry out.. i added a half tablespoon epsom grow for M.G.. to my water mix.. 2 others have a similar problems but the leaves curl up and in from the sides. Is this due to a lack of Magnesium or does it sound like a nutrient lockup? Iv'e never had this problem before. Any info would help.. Thanks
check the PH..... if u can a pic it will help alot.... right now it sounds like a Phosphorus problem.. look in here, and see if u see any familier looking to your plant http://www.geocities.com/nutrientproblems/
I have no pics sorry.. both of the pages really helped. i think one plant was over fertilized and the other looks like heat stress.. the heat stressed one is and outdoor strain that is being grown indoors for the first time. i dont know if that makes a difference.. but i use a 750W Hps and i haven't had this problem before.. Thanks for the info I'll let ya know what happens..
