It's nutrient lockout due to to nutrient toxicity. Don't feed more than 700 PPM (you are giving them 3 times this strength) just flush and flush and let the plant consume the excess nutes it has

Hi there! From what I can see, your leave's tips are becoming yellow / brown / crispy, this could be a sign of a nutrient-burn, if extra cal-mag doesn't solve your problem you may want to flush her for a couple of days. Also, how far was this leaf from the light? I'll be around, good luck with this beautiful forest!

Brown yellow leaves?Can anyone help me? I had this issue with my last early Miss and thought it was a cal mag deficiency. I tried to adjust it last time during flower but it didn’t help. I really only notice it on one of them so far but I would like to fix the problem sooner than later.
