hi these are my 6 fast and vast autos under a 600 watt hps dual bulb, Wilma 8 pot hydro system with 6 inch fan and filter with 2 other cooling fans in a 4x4x6 tent. These beauties are only 35 days old, they have been on bloom muted for 8 days. Ppm is 900 and ph is 5.8-6. 20/4 light. Is everything looking ok or any tips. I haven't really touched them apart from taking the odd yellow leaf from the bottom and tying the biggest one over a little to stop it getting to close to the light. Many thanks
