A question from a fellow grower:
Hello! I was wondering if you would be able to help me out. I have posted my problem on several forums to no avail. Not sure if you would write me back at all with any info but here it goes. I have 2 girls, both flowering. I am a first time grower, and have not had any issues up until now. I recently battled with some clawing in my Sativa which I believe was due to N tox from what I have read. Well I added sawdust to the soil and the clawing is slowly sorting itself out. Now both my girls, Indica and Sativa both have browning leaf tips, they are curling upward and some of the browning is happening in the middle of the leaf rather than the tips. It must be some sort of deficiency but I am having trouble figuring out what its lacking. I don’t want to keep trying by trial and error, as I would like to have a nice decent yield with good smoke. I added Epsom salts to the soil. 1 tsp each plant. Is it really that deficient in Mg? Could it also be Phosphorus deficient? Any help would be greatly appreciated!! Cheers!
