First grow 19 from Kask, coconut light full spectrum 4 at 240 pH 6.5 gave 900 ppm and then 700 until drainage so a couple of liters flowed out today. The yield was 650, it's not so visible in the photo but in reality, some leaves are dry at the tips. Help me out growers, I don't want to mess up my first grow, thanks a lot!
