60x60 Critical SoG (first grow)

We start 4th week now. I managed to go down with temperature during „daytime” by changeing to a small 60W LED. Lights on and we finaly are under 28 Celcius! Lights off is around 28 Celcius as we still have perfect weather here. The plants show minor heat damages. I introduced LST on day 24 and realized I should done it about one week sooner. (First grow and no experience) Ended up breaking the tallest plant.. As she did not have much going on on the lower parts (not many new leaves or branches) and her leaves were stealing a lot of light, I decided to remove her Now theres only 5. Day 26 I watered them with nutrients. It was exactly 7 days after the last watering where I gave them 1-1,5L water with 2 ml Top Veg + 2 ml agamic per plant. Now its the same thing. Around 1200ml of water with 2 ml of Bloom+2 ml algamic per plant.
