Hope someone can help. I woke up checked my plants and 1 looks like this. They're beginning 4th week veg in 5 gal fabric pots and 50/50 of ocean forest and happy frog. Using a SF2000 in a 4x2x6. Light is at 50% distance of 28in 20/4. I've only use cal mag when watering 3ml per gallon. Temp is 80% RH 65-70%. I'm open to any and all suggestions.

I just realized the ro water I assumed was atleast neutral has a ph of 8.5 before adding cal mag. My tap is 7.5 and 104ppm so I'll switch to that until I get some ph down

Don't overdo it on cal/mag. While cannabis is a calcium hog, calcium can lock out almost any other nutrient, if too much is present.
BTW, my experience with FFOF is that it used to be hot. In more recent years, the mix has been milder. This could be a regional thing, as I believe it is mixed in different parts of the US. When I lived in the Carolinas, I used to have to cut it with soils that had no nutes. In Michigan, I've planted seedlings in it with no ill effects.
