Micro Grow - First time grower - Gelato

I needed to do some defoliation on #2, her leaves were covering a lot of the new growth. I noticed she was stunted during this week. Meanwhile, #1 grew with all her strength. They're drinking 200ml per day now, I'm considering increasing this rate to keep a low maintenance. I bought a new LED Pannel, it's arriving next week, and I think the girls are going to love it! Anxious to see the results of it. Those small lamps have taken me so far, but it's time for improvement!
