The 3rd, 4th and 7 pic are all of the same plant. It's an outdoor grow so I dont think its burned. I think its calcium deficiency. i had tomatoes growing in there and the all had "Blossom End Rot" which is a calcium problem. So thats my guess. lol. It sorta is 3 diff grows...lol.. the 1st pic and the pic with the two larger plants in the 5gal buckets are my "main" plants. All the little ones are clones. The clones that are flowering are being used for seeds. In all I have 8 mothers, 5 clones for grow, and 6 clones for seed.
