Sorry I forgot to respond yesterday man. I occasionally might get a twisted leaf in veg I honestly usually just make sure everything seems normal and ignore it unless the whole plant is freaking out.
Checking/resetting ph is where i would start.
It looks like they are growing good now. I would bet another week and you could flip them to flower.
Usually around now I remove the lowest 2 branches. This encourages upward growth instead of outward. I also do it to keep the plants from wasting energy growing lower branches that won't get good light. Some times I'll do it one time in flower at the end of the stretch too. I never take a lot off though. Just gentle pruning to help direct the growth.

Yes... if the pH is out then the plant isnt taking up nutes properly. The question in which ones arent being taken...lol

Yes... i started there. Like Hydrored i let my pH drift from 5.8 to 6.2 and reset to 5.8 again. I like his logic about the drift. Anyway, ive been checking my pH twice a day. At lights on then shortly before lights out so i know ive been spot on there.
The reason i suspect cal-mag is because i went really light on it last week....
Anyway, the first week i saw a couple abnormalities on a few plant and attributed them to shock and whatnot because of the shit they went through getting to me and how i started out.
But a couple days ago i noticed every single plant had some twisted leaves and some new shoots with completely mismatched leaf sizes, which is why i was concerned.
I did a res change yesterday with a proper mix, according to GH feed chart, with a full dose of cal-mag. Hopefully that will sort things out....
I plan to do some trimming on the stalks, a light lollipopping for lack of a better word. I just wanted the roots woven through the hydroton solidly before i went after them with the clippers, which is right about now as you said. Lol
Would still like to know what i did that caused that odd growth. I suspect cal mag just because it was the one thing that was significantly off. I think i half-dosed it last week...

I dont see Cal/mg being the culprit to the leaf twist issues. I'd guess RH or pH before anything. Seems like you have a very solid grasp on what a good environment is supposed be but just for the sake of asking...whats your RH at while this was going on? Usually when I see issues with pH, I usually see a leaf color change of some sort associated with it as well along with a slowing of growth.

Hmmm.... never thought of RH. It could be a problem. Its been so cold here (-30c) since the day i got my clones that RH has struggled. Highest it has reached is 42% during lights off... during lights on its dropped to as low as 35%... so i have kept ambient temps down around 77/78f tops... usually 75ish.
Never wouldve thought of RH...
Growing in promix, i never had a problem with low RH, even under HPS...

I meant to comment on that. I don't adjust ph more then once every 2-3 days.

I dont adjust pH twice a day. Just check it twice a day to make sure its good and to get a feel for timing on the drift. So far i havent had to adjust between res changes. I pH to 5.7 or 5.8 ish and it drifts upward for a week to 6.2ish. Then i do a res change. I just did my 3rd res change yesterday.
The white top is to keep light off the roots. I dont think it has caused a problem, but i cant know that. This is my very first go at hydro, flood and drain.

I just check twice a day... not adjusting twice a day. Havent had to adjust at all between res changes. I figure thatll change once the plants start going hard.
Also, on a side note... the ppms done really change either. They stay pretty much where they were from res change to res change. I dont think thats right... i would guess they should go down from drinking? I dunno... maybe when they get bigger?

That's good your not having to adjust every day.
I usually only change my res about once a month. Every 2-4 days I check the levels. If it's down a lot I'll check ph and ppm. If the ppm is dropping then I'll top it off with nutrients if the ppm is staying stable I top it off with ph'd water. If the levels in the res haven't changed much I leave it alone for a few more days.
What's your ppm at?

First week was 450. 2nd was 850.
Now im at 1200.
Just following the GH chart. Im on the transition wk 3.
Next week i got to bloom numbers... then i think it stay like that for a few weeks until PK numbers increase.

They were during my first week... drowning in overwatered roockwool, which i stripped off now.

Did you notice this start around the same time you jumped to 1200? They might not like it that hot. Honestly that little twist still doesn't look too scary. If everything else is looking good.

Naw... the twisting and missizing leaves started a couple days before i switched to 1200ppm.
I dunno... maybe its just schock of the transport and rockwool drowning just working itself out... or maybe its just a spazzy weird strain... it was purchased from an LP in ontario, only because i didnt want to wait for my mom to grow out.
Having heard how fast things can go wrong in hydro i just want to stay on top of things before they go too far...
Also, this how to learn right? Lol

TBH I dont see anything too alarming in those pics. I'd just keep running the course youre running. @Thundercat giving some solid advice.

Would PM mold cause funky growth?
I found some on a number of clones while clipping tonight... ffs.
Figures. The LP weed up here is shit. Seems the clones are too..

I dont believe so. It just grows on the existing surface. Get you a small tub of Green Cure and follow the directions. When you foliar spray them be sure to get all the leaf undersides too.
