Hello. For a couple of weeks now i've had issues with dark green "spots" or "shades" on the leafs (for lack of a better word). They are a bit darker than the pictures shows. Some of the leaves are starting to get soft, almost leathery texture. The upper leaves are starting to get pale/brown tips as well. This has not escalated to a great extent yet, but I want to be a little forward thinking. It may be too much nitrogen, but i haven't had any similar issues before so it's hard to tell. I'm currently in week 2 of veg (Dutch passion auto ultimate). Climate: 77 deg. Light on 64 deg. Light off 67% humidity Fert: -Autopot 4 Gallon -Easy2grow liquid fertilizer (1 component) -850 EC -6.0 PH -Coco coir Light: -445 ppfd -600W HLG Diablo -34" hanging distance
Change to canna coco a+b and sensi calmag has crossed my mind. I used my current fertiliser in my previous grow (same strain) and it made some serious buds without any major issues, so i kind of stuck to it because of that and it's conveniency.
I don't notice either magnesium or sulfur in the ingredients. You may want to add some epsom salts to the solution since this is magnesium sulfate salts.
