I need some help please. This is my first grow. These are Gelato that are 35 days (5 weeks) from sprouting, I use GH Flora Series at light strength. 1/4 tsp. per gal for week 2 and 3 and 1/2 tsp. per gal for week 4 and 5. Have a 1/4 hp chiller at 68 deg. Light is a HLG 550 v2 R-Spec. RDWC 13 gal pails. Reservoir holds 58 gal and changed every 7 days. PH kept at 5.8 RH kept 45 - 65. Temp 74 - 78. Curre3ntly the light is 40 inches from the top of the plants. The light can go up an additional 10 inches and that is it. These were topped at the 4th node a while back and have been at 24 hours of light since sprouting. I wanted someone's advice if I should start 12/12 lights. These have grown really well but they seem to be more like bushes than taller plants. Would you veg another week? I don't want to run out of room. Thanks in advance for your thoughts.
