Leaf curling up after feed

One out of six plants after feeding ,the leaf started curling the rest of the plants just had a shiny dark green look to them. I assume this is over feeding i gave about 700 ppm using GH flora series + cal-mag for the R.O water and PH is 6.2. This is my second grow but first time using coco I gave each plant about a half a liter each of nute soulution. I was thinking to flush with plain water but will that hurt them even more? should i wait another day then flush? also if anyone has experience in this strain please advise me on a good feeding schedule for these ladies!

any comments or advice is really appreciated thanks!

Looks like your plants are hot.

Curl down-overwater or overfert
curl up- heat stress
Twisted leaves- ph problem

My temps stay 77F and 80F max if its a hot day. I have a 400 wat MH cooltube and 3 cfl 23w I keep both about 1-1/2 ft away from the tops is this too close?
thanks for the reply by the way!

Maybe a lil close for the 400w.
How does the new growth look?
A flush is never a problem when you think something is wrong.

new growth looks fine its just the leaf in the picture ,ill try raising the lights too. Also i noticed that the one plant that has the most curls is the only one close to the fan, could that be the problem? defitnitly going to flush as soon as the lights come on! thanks again!

The fan shouldnt make the leaves curl, but a fan can cause leaf damage if the fan is too high. The leaves will acually cut other leaves with the sharp edges.
IDK man...you probably overferted just a lil bit. As long as the new growth looks good, that tells you the current health of your plant. Good luck and happy growing!
