Nutes

Just an opinion and I know you know that😉. Just echoing what others have mentioned as well. I see a Nitrogen toxicity that's causing the lock out of magnesium and calcium ( copper spots-calcium, yellow streaking outwards from center of blade vein-magnesium). The dark green hue is why I feel there's a toxicity with nitrogen but it can also look like a nitro deficiency. Confusing. I can only suggest a lite flush of balanced distilled or tap to remove excess but throw in a dose of Cal/mag and probably some phosphorus too boot. This may all be incorrect and if not seeing something, please hit me up in PM and we can go further with your tent environment, ppm and pH readings. This all being said, I hope this helped somewhat and I trust everything will be ok 👌
