Day 24 of veg, topped four of the plants since the small ones need time to catch up. Strelka and Forbidden Dream being the smallest ones. I water once daily for 10 minutes, but all of the water wont get out of the tray. Im going to veg for 10 more days atleast.
Bro, dark green leaves may be a sign of phosphorus deficiency, and yellowing of the tips is a sign of potassium deficiency. In my opinion, it is more likely at this stage of flowering.
