Plants are about 6 weeks old. All of them are different sizes the biggest one 14 inches, another at 11 inches and the other is 8 inches. I just started feeding them nutes because it took forever for the soil to dry out. Only fed them a half strength solution and i have them in a 4x8 sunhut that i just recently split in half so now its 4x4. How much longer should i veg them out for?
