Alright I haven't been of here for awhile because I don't have a computer ATM but I restarted all my plants with what I was told was some skywalker but I figure its just homegrown. Anyway they were doing way better then my last but then recently they started to droop and on two the top leaves are turning sideways.also some of the bottom leaves are turning yelloww and dying but its none of the big leaves just bottom leaveas near soil. I haven't given them any food yet and their only 4 weeks old today. I just changed the lighting to 18 and 6 to get them ready for flowering. I'm using two 50 Watt cfl 2700k 2 26w 6500k 2 23w 6500k and 2 tube flourescent 6500k but will be changing them to 2700k. Thing I want to know is what's wrong of course but the plant that looked the worst droopy wise but is the biggest plant I took outside and it perked up super well no droopyness. Why is that? And is is fine to do the same with the others? Last thing which I almost forgot my plants aren't in flowering yet the they all sexed. I had one male and have 3 females. How?
