Leaf Twist?

[Underground Scientist]

I have plants at several ages here. I'm getting leaf twist. I run Sunshine Advanced #4 mix which is a peat, coco, perlite blend with dolomite line and silica. I've had some cal Mag issues, but always use 4ml/gal of Botanicare Cal Mag Plus with my RO, and GH Flora has Cal Mag in it as well. I PH to 5.7-6.0. Should I increase my PH? I've always heard stay a little lower in a soilless mix, but I'm starting to wonder. Temps are usually 70-80 and RH around 40%. Here's the weird part. My plant in flower doesn't have this issue at all. Same soil.

my guess is uneven watering.

Looks pretty good to me. Remember not to over care for it. I would continue doing what you're doing. Just make sure to water thoroughly and make sure to give it plenty of time to take it all In, whether it be a day or a week. Overwatering is a very easy mistake to make at this stage.
Could also possibly be the positioning of your fan. If they get too much constant breeze it could be damaging. Hope this helps.

That doesn't seem too bad. My can doesn't directly blow on plants. The seedlings get a little direct but it's just a muffin fan, nothing strong and it doesn't visibly move them. There could be some truth to uneven watering. Those seedlings were planted in the 1 gallons from day 1. I did carefully resaturate the top when it dried out. It's going to take time for roots to access all the lower soil, and I can't risk drying the new roots out, but I can't over do it with water or...duh, overwatering. I've seemed to have a calcium issue with plants early in life. I add Cal Mag, even precharged soil this time. Some of my plants have almost crimson red stems. I end up scratching my head cuz I add 4ml/g of Cal Mag every watering, and GH nutes has healthy amounts in it as well. I can only imagine a ph lockout being the culprit.
