Dying plant. Please help

leaves and bud sites getting extremely dry. Running dwc temps between 70-75f water temps 68-71f, RH is 30-40%, ph is between 5.5-6. Running a Mars hydro 600w.
Please can any one give us a hand on trying to figure out what's going on.

Some of the bid sites are growing and in good condition while others are wilting and extremely dry. Lights are 24" away from top of canopy and rotating buckets every day.

Yeah sorry about that was taken at 4am this morning before work. I'll post some better photos up tonight.

Some More photos under normal lighting. Anyone got any suggestions?

how close are your lights? Looks like possible light stress.

Lights are about 24" away from top of canopy. The worse effected areas are furthest away from the light as I though it was light stress too. Been 4 days now and doesn't seem to be getting better.

What do the roots look like? White or brown?

Have you looked up "broad mites"? I've never had them myself or any damage like that but from what your saying its worth scoping the damaged areas with something powerful atleast to check.

Roots ant white but not brown more like stained from nutes.Water temps have always been below 72f. It could Possibly be root rot but roots ant slimy or smelly. Nutes get changed our every week

What's your PPM/EC?
It's look to me that you are cooking shit out of them

Root aphids can get to hydro roots. You may want to check carefully for aphids or mites. At this point, it seems the most likely... but there are better growers here for sure, and I'm not a dwc/hydro grower......

Yeah been researching broad mites and it has all the symptoms of them. It is slowing starting to spread to other plants too. Need to resolve asap.
