Not using enough calmag brother . That's the issue . Up your calmag to 0.8ec and then add a and b for the rest of your available ec. for starting them right from seedling . You need to keep the coco buffered or you'll get get yellow and droopy new growth. About two weeks into flower you can drop the calmag ec back to about 0.7 and replace that 100ec with a and b
Thank me later dude . I grow 6-13oz autos per plant so just trust me bro give it a shot next grow .
