Whats wrong here?

Hiya
20 day old Strawberry Cough having issues. Temps/Humidity normal. Keeping pH in 5.8 - 6 range. She was on a very low 200ppm its stable at 650 now.
Distinct wrinking of leaves.
Any ideas whats the problem?
Thanks!

Ppm needs to be like 350

lower your ppm like ariwalker said.

and if it's just the bottom set of leaves (first real set), mine always get to looking like that. as long as all the new stuff is fine, you should be OK

Sorry, tap water is 200 so she's at 450 now dropping slightly.
Yeah I expect the lower leaves to die off but this seems very early.
Cheers!

I'm heavy in flower, with my RDWC, and my TDS is around 530. I usually stay below 600ppm.

Even 450 at this time is too high. You should be around 250-300 ppm. You shouldn't be expecting anything to drop off until the later stages of flowering. However, damaged leaves won't repair themselves, so at some point, well after you've gotten on track, and you are trimming in veg, you can ship them.n I'd just leave them for now. Look at your new growth to see if problems are persisting.

Cheers, she was up to 520 and its dropped steadily but she's looking a whole lot better! Whatever it was with those leaves didnt get worse.

Ok right. that seems pretty low i was up to about 1200 last grow.
I generally work on the 'if it goes down, bump it up, if it goes up lower it' is that not what you do?

1200 is far too much in DWC. Roots are floating in that water 24/7. They can uptake constantly. It's much different than soil that once dries out, slows/stops uptake.

I like to bring it up to what the plants can take, up to a tiny bit of burn on the tips of the fans. Then I just add water for around a week. The TDS stays constant for quite a while, with a large water supply. When it has dropped down a couple hundred PPMs, I'll pour a 1/4 cup to 1/2 cup, depending on how far in veg, or flower they're in. Basically bring it back into the 500s. That's "500" on top of my tap water ppm.
