Info about your grow please?
Medium, nutes, feeding schedule, pH, etc.
Hydro/coco 60/40
Dutch pro a&b 2ml of each per liter
Dutch pro cal mag 0.5ml per liter
Dutch pro explode 1ml per liter
Ec 1.4
Ph 5.8-6.0
I have just checked my run off and it was 1.8 so i have ran a few jugs off feed through it and got the run off down to 1.4
EC is too high by the looks of the beginnings of the cupping on the leaves. See how they are beginning to claw down.
I would back off EC to around 1.0 and watch what’s happening coming out in the runoff until it subsides.
How often are you feeding?
Are you feeding to substantial run off?
Get rid of the runoff , your medium will get toxic, probably nute lockout.Every day i water between 1-2 liters till i see a bit run off rhen i leave the run off in tray to be soaked back up by plant.....
Grow shop guy told me to this when i says am wasting loads feed with run off

Better give them a good feed with plenty of runoff
That's why they call it drain to waste hydroponics.Every day i water between 1-2 liters till i see a bit run off rhen i leave the run off in tray to be soaked back up by plant.....

Yes im going to flush my 12 plants with 1.0 today when i get home.... then il be back to doing what i was before with the run off
any picsNo need to flush.
just adjust to 5.8pH EC 1.0 and keep at that for now.
In 5 weeks veg and some amounts of 12/12(not really tracking flowering time) and mild training and I haven’t exceeded 1.1EC with 0.2 source water.
Currently feeding every other day.
3x11L pots
2x5L pots
25L of mix is doing 3 feedings with about 10-15% runoff at currently 0.9EC
0.2 water
0.2 calmag
0.5 A/B
0.5ml per litre explode
my plants if left untrained would be around 2-2.5ft tall.

Dutch pro is not great in hard water areas and its also super concentrated so go for half strength, you have phosphorous/potassium burn and the clay balls on top of your pots will heat up under the lights and when you water they will heat the water up so maybe cover em up with a little coco.
additional cal mag isn't required unless you see yellow veins and red stems also with dutch pro i always used a silicone supplement
No need to flush.
