Freedom! At last! First Grow

Finally received a new, much larger light- a Mars Hydro TSW 2000W panel just as at least two plants began flowering towards the end of week 5! I was hoping to transfer them to larger pots but they started getting yellow leaves , some with brown spots starting from the lower leaves, working up. So, I flushed them with water only. I went and bought some cal mag and started using it and started using the Tiger Bloom and Open Sesame. I also purchased a PH water meter and soil tester and realized the water I was using was at 7.5 and the soil was at 5.5. The PH of the runoff at 5.2. Whatever I did the leaves stopped yellowing and drying up. The tallest plant, #2, Silky, seems an almost all Ruderalis pheno and is almost three feet tall and the shortest, #3, Gladiolus, mostly Indica, is one foot tall and about the size and shape of a bowling ball. I didn't bend anything and took off only the dried up leaves and moved some of the big leaves to the side of the shoots, so they both get light.
