Lower leaves weak and dropping

[goldentailwag]

Earlier in the week I had some serious claw or dark leaves curling down, lowered ferts and seemed to have gotten better but still have some wilting on lower leaves, kinda seems to be stunted too.

Current params
RH 62%
Temp 77
PH 5.9 stable
Current EC 975 and slowly
lights currently @ 500w of 1000w
Ferts General Hydroponics with RO water.
Strain OG Kush.

They are definitely stressed

Not 100% sure how dwc works water wise however it looks like they got to dry as well as stressed from the light

They are light stressed you can see the blistering
Haul the lights to about 25-36” away

I won’t get into the ro water thing however unless your tap water is no good I would use that instead as ro water has the goodness removed

Thanks, I actually just lowered the lights a couple days ago so thats probably it. Just jacked them to 36" I have well water with high calcium apparently, my last and first grow had a calcium layer on everything I had to keep up on. The RO solved that and I do add cal-mag.

G Mix is right on.
Also over fed.
E.C ?
I'd skip the R.O and use the well water. Really.

I will skip the RO and go back on well. EC is around 975. They were close to 1300 earlier this week. What EC you recommend at this stage?
