I'm wary of too much N for any strain mate after overdoing it in the past.every mephisto girl ive done ive always had to go easy on the nitrogen first one I did stunted her with to much canna A+B and it was only 1.5 ml per ltr dropped it to 1.25 ml and she was fine
I only added about 15% super coco and I've grew in 70% before without issue.She's only had RO water and root juice up to now.
I just feel there's more to it than overfeeding.
