Wrinkly Leaves?

To me some of the leaves look a little weird. Is it because I sprayed them with azatrol when the lights were on?? Also tips are curling down, is that because they were over fed? ph seems to ride around 6.1 and ppm just under 700. medium is bcuzz coco. What do you think? Im trying to get these to veg as fast as i can.

Leaves that droop around the edges usually means there not getting enough light wrinkles usually means you singed em wih the light being to close or your Ph is off i had some master kush leaves wrinkling on me 6.5 ph in soil was to high then i dropped it down to 6.2 and 6.3 wrinkles fixed them selves there was also weird uneven growth try fucken with your ph

yea thats normally what i do to fix this but since its in a flood and drain table, the nutes recycle and the ph of the reservoir is pretty much the same as the run off of the coco. i check the ph before every watering and it seems normal (around 6.0). I flood once a day. Im thinking its because of me spraying them with azatrol and not turning the lights out for them to dry. edges of leaves are not drooping just the tips are curling down. idk what do u think?
