please help me

I believe you have pests....may be spider mites or thrips. Can you take a closer picture and check the underside of your leaves for little critters.

Toxicity. Clawing leaves, most probably nitrogen. But i see some magnesium too, could be aftermath of first, could be wrong ph and absorbing issues. Could be watering regime wrong or she is in lockout and you spoiled her that way. In soil - plain water , phed to 6.3, dechlorinated, for 3-4 cycles at least. Wet/dry cycle is a must too. If she is in lockout top lair can dry out, but bottom will stay full, only lifting pots will tell you when to water. I saw plants returning from way worse. Just back off !!!! Watch ph and all should go better.
