Ive always been the opinion that plants needs to be pushed pretty hard with nutes at a fairly young age, to maximize their potential. Push 'em hard...just not too hard...i would rather be on the edge of toxicity, than the edge of deficiencies with the group as a whole. And then continue to push hard(but not too hard...LOL) with flower nutes to maximize production.
Yeah see I don't do that. I mean I gradually increase but by that time I guess it's too late. I definitely have more rust spot issues with LEDs I haven't really been able to fully conquer. Maybe I just simply need to feed more.
