Hello everyone hope all is well.
Have some issues with my girls.
I notice some slight tips claw downwards & Dark fan leafs.
So I figure it was nitrogen toxicity.
I flushed with tap water at 6.5 ph for 2 feeds.
Then I continue the usually feeding schedule but with half strength of nutes. Current will be 2nd day of half nute after flush.
But doesn't seem to be better. Kinda of lime ING out.
Abit worried any advice will be greatly appreciated . Try to provide the most relevant info below hope it helps.

CURRENT WATERING INFO

Currently only running based nutes at half dose(500ppm 6.5ph)
Soil PH 5.8-6.4 based on bluelab PH pen
(It Calibrated I don't know if it acc)
Run off 6.4ph PPM 500ish
water in reservoir does seem a little higher after feed 7.0ph

Some info

4 by 8 Tray grow
2 1700e LED GRAVITAS
Room Temp 80-83F
Humidity 55-65%
19 days of flower
Tap water 8.2ph PPM under 200
After nutes 1000-1100 PPM 6.5 ph -7.0Ph
Medium is soil sunshine pro mix
circulating drip

3 Part GH
Cal mag
BudCandy
Superthrive
5 Ml per gallon For mirco

3 part gh sucks for soil. It's great for hydro. I see youre only using the flora micro and flora bloom. No flora grow?

and thats not even counting in leaf surface temp, you obviously have an n issue, and possibly a p/mg issue with the purple stems. your plants are sucking up water fast and they bring nutes with them, if you have a toxicity in n you can either lower e.c or lower vpd and slow down transpiration

I just looked at some of your past posts. Roger is still right

they look like they're nute burned...badly.
and overwatered....badly.
if the rest of your plants are in the same conditions and look good, check the roots on the ones that look bad, see if they look healthy, see if there's any bad odor

At least this time you're merely burning them not over watering because soilless LOL

Way too much going on in your nutrients. Stick to the flower with a tiny bit of micro and cal mag.
no need for superthive and any other additives, it just creates more problems.

what you have is a lockout going on.

less is more.
