Twisted new growth - reoccuring issue, need help

[eFeNGee]

What's the Common denominators between both grows (soil vs coco), both with the same issue?

Lights
Water
Fans
Nutrients
ec/ph pens
Co2
???

You've pretty much ruled out lights. (with your setup, you should be able to blast them @ 100% if desired, anyways)
Fans should be irrelevant unless blowing directly on plants at hurricane strength
Bad batch of Nutrients could be to blame but unlikely. No burnt tips = not over feeling

That leaves the pens and the water. My bet is on the water and rootzone O2, and or ph levels (even though it's RO water)

What pens are you using and how often do you caliblate them?

Tell us more about your water... You said well water, does it go through a water softener prior to RO? How old is the RO membrane? How do you collect and store it? Does it sit 24hr b4 using? Do you have a circulation pump or air stone in it? Do you ph it b4 or after mixing nutrients? Are you mixing ingredients in the proper order - Silica 1st (if using) then calmag, then micro, then base

You can test water hypothesis by using distilled water to mix for one plant and see what happens

The beauty of hydro/soilless growing, is that if problems arise; you can always dump, flush and reset and it's like starting brand new

With your setup with Co2 and all, they could be outgrowing their root zone O2 levels and getting "soggy feet"



My bet is that it's still something to do with your water.

Just my .02 on the O2, H2O and the CO2... lmao

*I personally would eliminate Co2 supplementation until you get this sorted out

Oh, and welcome to the farm!

Oh thats a lot of questions
The RO membrane is brand new as well as the pH and EC pen.
The RO is Growmax Water Maxquarium 000ppm. I got two ph pens since the old one was getting old. Old one is Milwaukee, the new one is Aqua Master tools p110 pro 2.0. Both calibrated a month ago, both reading the same ph.
I collect the RO into a plastic tank, usually i collect 50 litres, add calmag to 0.3EC (approx 6 ml per 10L) -> canna coco a+b (20ml per 10L each) -> adjust PH. Then the solution sits in the tank overnight being mixed by circulation pump. In the morning i check the ph again, adjust to 5.8 if needed, water with 20L. Next watering is in the evening, again 20L, this time a let the ph drift to 5.9 or 6.0. Then the tank gets refilled to 50L.
No air pump tho.

Edit: water goes from the well right to the RO, no prior softening.

If that fan in the corner is it on? If so going to say the whole grow has too much wind and in a 2.4 that's actually a lot of fans..

Your sucking too much water from leaves why they taco.

Many out thermometer and humidity meter in the lights reads wrong too then they set the environmental based if bad data.

Hope that helps

Wet feet and slimy roots fits. It is also easy to check. Sacrifice the worst plant and examine the roots. It is totally possible to over water coco. I have had a few plants where the root growth was so dense that the water runs down the sides. The bottom of the pot just becomes a soggy mess.

This one is just sitting there doing nothing :D Only two oscillating fans are on and those are way up blowing air at the lights.

I've checked this morning, didnt sacrifice the plant but i saw a lot of clean white tips growing through the bottom of the pot.
Also i've noticed that my environment controller says 65% rH, but the air scrubber and air quality controller says 75-85% rH. If my environment controller is reading false rH value, maybe the VPD is so low that the plants cant transpire properly, fighting the heat with canoe instead of transpiration? That would explain why the pots are always wet. I've dropped the rH to 50%, will let you guys know if it had some effect.
Thanks for all the inputs!
