Yellow leaves and curly leaves

You also mentioned temps are 77F. I'm assuming this is ambient temp? Another possibly tweak is raise your ambient temps to around 83F to get your leaf surface temperature up a bit. Leaf temps are typically a few degrees lower than ambient under LEDs. I'm betting your leaf temps are around 71F give or take. Wouldn't hurt to get them up a few degrees to get your plants transpiring better.

Leaf temps are around 80.
I’ve also dropped the RH and flushed the resevoirs.
No noticable change yet. But I’ll keep you posted.

You say you flushed the reservoirs, did you flush the plants?

Roots are in the resevoir, so they are automatically flushed. You can see the roots a couple posts back.

I’ve run an Ec of 1.8 in dwc without any problems in the past. I have this feeling it also depends on the type of nutes you use.

I run a RDWC with PPM between 1000-1200 (EC =2.0-2.4), with GH Trio + calmag + Si + hydroguard. (I also supplement CO2, that'll support a higher nutes level)

Are they eating?

Ghe soft or hard? How much calmag do you add?

Plants are recovering, dropped in today and they are starting to stretch and turning a little greener. I made some adjustments to rise temps and lower RH further. See how well they usjust to that.

Eh? General Hydroponic FloraMicro, FloraGro, FloraBloom (on the 'aggressive feed' schedule).

I use 2ml/gal CalMag. Same for ArmorSi.

There is two versions of the micro :)

I think he's referring to the micro part of your formula, are you using what's ment for hard water.
Edit: Took me a while to find a picture lol

I had no idea! No, the regular version. Which I use with tap water passed through a chloramine/chlorine filter.

yeh I had no idea that they made Hard Water Micros.....

I won't change anything though cause it's right on as is.

Good news, we have green happy growing plants.

What kind is that do you know?

My stuff looks VERY similar to yours.

Strain? Its peyote critical

I run a ro system and the hard water micro is ment for ppm's above 200.

I switched to the hard water one these last few grows and have noticed no difference.

We are doing great over here :)
