Is there any way you can use ro or distilled for now? For sure has a nutrient imbalance since there are no root issues and light is ample. Ill tell you this, I use flora trio with
calmag and RO. I start at 7ppm ro, I add
calmag to 100pmm. Then you can add your normal ratios on top of that. For where your at, id just use .5ml per gal off all 3 bottles and lower your ec to like .3 or 300ppm.
Id go to walmart and get like 20 gallons of distilled for 20 bucks for now and do what i suggested. Easy fix in my opinion.
I dont go over 400ppm for veg. . ever, using flora trio. Now if you have a bunch of other things your adding let me know. Since your using peroxide I doubt it lol. .
For the first 3 weeks my plants basically get equal ratios of
calmag, micro, grow and bloom, prolly not the fastest growth ratio, but i get no issues.
