To start with I have 6 plants, at 4 -5 weeks of age, gender unknow as yet. Bag seed, soil grow, ph 7.0-6.8 cfl lights, just gave nutes first time today 25% of recommended amount the leaves were all ready like this before. only 2 plants have the yellow bottom leaves as shown in 1st 2 pictures the 3rd pic is of a plant that looks droopy and has looked this way from the start. I water all at the same time, and use a moisture meter to check them, before watering. I'm not in a panic over this but was wondering if I should remove the yellowing leaves or let them be? the droopy plant, is a question, is it just a different strain? because it does continue to grow, but all ways has looked like in the pic? I would appreciate and comments or suggestions!!!
