You missed one. Do you have adequate oxygenation in that rez? I.E. Do you have an airstone in there bubbling.

You should, especially if you are not dripping constantly.

I thought of 1 more thing...You have 6 plants in that on unit? What are you going to do with the males? You know the more they grow...the rootball will intertwine with each other, and you won't be able to get them
apart. I never put more than 2 plants/clones or 1 plant/seed in that size rez
