Your soil is toxic and it will kill your plants if you don't flush her soon. Try coming from the other end of the spectrum nute wise and you'll have better luck.
And follow a more conventional regime nutrient wise. Infact with soil, don't even add nutes. Myco's only. Keep it simple. Wait until you see signs of deficiency before adding nutes again.
As mentioned above, flush with ph balanced water. 3 x pot capacity and leave her alone for a week at least. Limit your variables and unknowns.
..and I hope your 600 watt light is dialed right down. These plant needs about 50w. Good luck, bro. Simplicity is key.
