Those lights are notoriously weak.Haven't seen any pest maybe at the very beginning there was a drain fly but haven't seen anything since. I think it might be nute lockout due to watering with distilled water pH of last runoff was 6.8to 7 but fixed since then and got lemon juice to correct pH for next watering. Yes both bloom n veg switch been on. Plus the extra light that came with the tent. Lights also on 20/4 says Bruce likes it that way
I had to use 2700 actual watts in this 4x8.
2700 actual watts.
It wasn't near as good as current lights but pulled a lot of pot.
Stay safe
