HELP! Twisted mottled leaves

[TRX]

I'm having issues with twisting and brown mottled leaves. I'm in my last week of veg and these plants have never really looked healthy.

DWC hydro grow. Advanced Nutrients Connoisseur. 4x4 LED Ion board.

What's your temp and RH?

[TRX]

Max 75° and 55% RH

How about CalMag? How do the roots look?
That juice looks interesting. It says you don't need to pH. That all sorts of excites me! Seems it could work for coco.

I am using CalMag, roots look normal no musty smell.

My guess is you are not checking the PH of your feed solution, but that looks like PH issues to me. How hot is it in your grow space? Any wind blowing directly on the plant?

[TRX]

Max 75° and 55% RH. I've got two AC Infinity oscillating, one above and one below canopy. Advanced Nutrients claims "perfect PH" so I've never checked on PH.

I would start with a double-check of all the basics,

The levels I state below are "just a guideline" that I use for myself, in DWC only, and I wouldn't expect any adverse symptoms, such as the photos you've shown, if I keep within these ranges.

Environment: light height/intensity, temperature, 24 degrees C - 28 degrees C, humidity, 50%-60%, air intake/exhaust sufficiency, no fans blowing too hard or directly on the plant

Nutrients: pH (5.5-6.2), EC (1.2-1.6 in veg), airstone/pump functioning correctly, airspace between net pot and nutrient level, etc.

root health; colour, slime/pythium, insect larvae within the root ball, etc

One more thing I recently learned the hard way is the compatibility of nutrients. Try not to mix different brands, and try not to use too many additives, as it can make things a bit more complicated,
Stick with the basics.

I'm interested as to what might be causing this myself, so please let us know what you discover.
Cheers.

Pretty sure that "pH perfect" only applies if the water you're starting with is the correct pH.... If the water is out the end mix will be out...

Im with geeza, go back and check the basics … i Think your ph is off. I use advance nutrients and even though most of the time i get very close to the correct ph it can be off sometimes. With advanced nutes you check ph after you add them ,Wayzee, regardless of water type it will balance the ph but you still have to double check. It seems the one thing the OP hasn't done.
