can someone tell me wat this is

atleast one of my plants always does this but i dont km\no wat it could be

What nutrients are you using and what are you growing in? It looks like some sort of nutrient problem but it's pretty hard to say from those pictures. Is this only affecting new growth, old leaves, or both? If I had to guess, I'd say either nutrient burn, a manganese deficiency, or a calcium deficiency, but from the pictures it doesn't really look like any of those to me...

I don't think its nute burn I thought it might b lack of nute like not enough so today I have it nute Ima c if tht helps

I use super nova. I'm in the flower stage right now. Table spoon per gallon

maybe its this stuff calld aza max for mites tht u put in the soil wen feeding...will it burn the plant.. i put a teaspoon in a gallon...
