Ppm To High? ?

[MeanGreen420]

Ok last two weeks been running at around 400 ppm/ph 5.8 but I had heat problems with rez and room 85f for both. With those problems plant still grew. I switched to qb boards now rez 76 and room 77, rh %47. Running at 200w about 12 inch from plant last 2 days. I come in tonight and see fan leaves looking like there drying up. I read cannabis care manual and says ppm to high and that the salt drying it up. I'm flushing now but what you guys think?

Yea a little too high, 150-200 till they really take off. Flush then go in 1/4 ratio for a week then 1/2 for a week and keep doing this to get to “normal” feed ratio.
