First Time Grower, Longer Term Toker

Plant 3 had some pH issues. Otherwise the plants are doing great. Plant 4 has been topped. And the other plants have been steadily growing outwards. I've managed to keep the plants under 6 inches thus far. Plant 2 is extremely sturdy in its branches. I have very little work wiggle room to manipulate the branches in the direction I want them to grow in. Water pH is around 5.6-5.7. I have been re-tying the branches about every other day.
