I topped this week. I also stripped a couple of the plants to experiment with mainlining. I'm getting eager to see some more growth in these guys.
I topped and mainlined the plants too, and gave them their first nutrients, 134 PPM, 6.5 PH water. Now I'm waiting for the new tops to grow out for another topping.
A few days have gone by and the plants seem to be doing fine, I am not doing much at this point.
