Cut back on the Nutrients for awhile until they start to look better, the PH looks okay, a bit on the hi side of the alkaline, 5.8 to 6.4 would be optimal in that medium, they don't look to far, cut back they should come back in a week or so.

Good luck.

I thought the the mega crop feed chart was wacky when I used it

What is the ppm of the nutes you are feeding every other watering.

That is caused by too much light intensity, I have the same thing going on with mine right now. In what size tent are you running the 600 watt lights in? I have a 3x3 running 600 watts and my leaves are burning just like yours. You could move the light higher up, or dim the ballast if it has that option.

and.....possibly compounded with a lil cal / mag def. Especially possible if that medium has much coco in it and/or using RO/low tds water. Mega Crop is a touch low in mag and cal for hi-perf indoor, many add some epsom, some calimagic.

you could maybe give them a bit 1/4 tsp. or so per gallon of Bio Ag's Cytoplus or TM7, in case it is a micro-nutrien deficiency

youd be better off giving them a full strength spray and make sure you put a big ass fan on them
But at 6.5~ he shouldn't be getting lock outs
