I'm 7 days into flower and the buds are starting to develop. You can see a couple of them in the pictures below. The tallest plant is about 24in tall now and the shortest one 22in. They are doing really well and are really healthy. I think the only reason i was having problems in the beginning is because my ph meter wasn't accurate at all and was causing my plants to have PH issues without me realizing it. I bought a new PH meter that was much better than my previous one and since then the plants have been very happy.
