These are some pics of the one chemdog left under the lights, her bottom leaves tips curl down like a claw. it looked like a zinc def. to me. I did a media drench with Mineral Matrix, then I diluted a little of the drench I saved and did a foliar application, the Chem Dog was given to me a few weeks ago, it was in little 1/2 gallon pots, I saw the problem then but figured transplanting would fix it and it didn't, The Mineral matrix is a 100% percent organic, and vegan micro nutrient, I really believe in it, because it works. the plant is 17 days into flowering, 22 days under 12x12. Hopefully I've got it worked out, I've got her 2 sisters outdoors, 1 in a pot and 1 in the ground. I'll be makeing some house calls tommorow.
Can anybody tell me what is going on with my girls... 3 week flowering, 4X4X5 growbox, DWC, foxfarm nuts. Following their schedule. By the chart above I think it may be a K deficiency but I'm not positive. The leaves eventually get darker from the center out and kind of disintegrate as they get darker spots on them.
I would really appreciate any info on this...
