how far do you have the lights from the plants now and on what level? i have the same light and got some light stress from level 6 and having them to close.
Sorry, just saw this. I have had my lights up all the way to the top of the tent since I set it up. I've been using the phontone app to check the DLI and adjusting the intensity to the recommended par levels. The light was 29 inches away last week when I posted this. Since then the plants have grown a lot more. I'll measure light distance again this weekend, but I'm guessing right now the light is about 26-27 inches away now.
I turned my lights up to level 10 today because we are having a cold spell right now and the basement where the tent is is hard to keep warm.
