Did you check for bugs?

Using diatomaceous earth and some pyrethrine for thrips. Looks like I will attack tonight with spinosad when lights off. Girls looking sad and I can spot tons of yellow dots allover the plant

I see them as well. Wouldn't hurt to defoliate a bit. I don't like those fan leaves touching each other.

All new growth looking yellow and tired.. going for some defoliation, spinosad, decrease light power and see how it goes
