First time grower: A two month old, recently repotted into 5gallon bag, using fox farm coco coir, mixed with super soil on the bottom, worm castings on the side soil. topped a couple of weeks ago. I am trying to do it organically (not feeding bottled nutrients), but I did take my time to repot since I didn't want to repot just after topping. Watering only when the leaves look a little droopy (which could be about 3-4 days in a fabric pot). I noticed a few lower leaves turning yellow and was wondering if this is nitrogen deficiency. Also I have never tested my water's PH level (well water), but for two months didn't see any problems with the same water. Any advice would be greatly appreciated! (I may have also left it out in the sun - some other plants that went out to sunbathe turned dramatically yellow/brown)...
