Another week with a lot of studing in order to understand what's going on, to then take the proper action. It hasn't been easy, most of the time I have no clue of what the plants are doing. I tried some fimming last week to help even the canopy but it didn't seem to work. Two of them are smaller than the others, I took the smaller one out of the center of the light to give the chance to the others to get more light since it wasn't growing at all due light burn, and one of them was too far from the light, so now is very stretchy. They have been growing fast, any suggestions on how to train them? I think is time to get a new light. I'm thinking about getting a HPS 600 watts, what do you think?
