I’m doing it at 2 ml a gallon

you using tap water or ro water,im asking for the reason your tap water has enough cal and mag in it making it probally to much with the 2ml added .
so if your using ro water and adding 2 ml cal mag,id say if def magnesium,from the purple stems and yellow between veins.
i use tap with my coco and use no cal mag,
also not all phenos are created the same,even same strain from same seed source,there can and are often some that are more sensitive

Got you and yes I’m using an ro system ppms are coming out zero and I’m mixing everything 1/3 of power as in the veg base and the root excelerator drip clean multi zen amino treatment nitro boost algen extract

Check for root aphids?

 

[oldskol4evr]

im still thinking 2 ml a gal is to much,try 1tsp of epsome salt in a gal of water and give them a foiler feed,see if it helps,mag and sulfur,if it helps then you know you need a tad more mag for them

I'd also check the roots/ underside I see a bit of algae on the cube tops. Just covering bases.
