What could this be?

Not sure what is causing this, everything has been smooth sailing up until the past two weeks or so. Pretty sure the problem I'm least worried about is a phosphorus deficiency, only with the few bottom leaves on both plants which as far as I know is usually some what normal to on the first few sets of fan leaves later in the flowering stage.

But I have no idea what's causing the deformed and holy leaves?
Maybe the start of a pH problem/lockout? The deformation is starting at the new growth so it has me a bit concerned.

Both are Bloody Skunk Autos from sweet seeds, they are on day 51 and 4 weeks into flower.

One is in a 2gal pot n coco and the other is in a 3gal pot in happy frog soil.

Nutrients I'm using is MegaCrop and that's it, I did just order GLN Bud Explosion for a PK boost so I will be adding that in the mix in the next few feedings.

I pH my feedings to roughly 6.2 at the lowest and 6.5 at highest, feeding every 2 days or so. I just recently started doing 2 small 16oz feedings a day with the coco, still sticking to 2 days or until it drys out with the soil.

I think I may have been feeding them a little too much MC and may need to cut back a bit? But at the same time it doesn't look like I have nute burn? What do y'all think?

I'm experiencing this too. Bump for information.

do u hear crickets at night? lol
looks like somethings munchin on your plant

Im thinking thrips... pretty easy kill on a young plant like that. Do some more research but if u come to agree its thrips some natural pyretherin and theyll be gone...

Well this same exact thing happened on my very first grow but it was bad, looked up, down and side to side for any types of bugs, nothing. I think it was a pH problem with my first plant, which is leading me to think the same about these two? But my feedings are always on point as well as pH. I looked at these plants a few times the past week, nothing. No signs of bugs. It’s happening to both plants, but it’s only on a leaf here or there.

I’ll keep, keeping an eye open and checking them daily. I also put a good lair of that stuff that acts as glass cutting anything that walks on the top surface of the soil. I forgot what it’s called exactly but I think it’s deomaceous earth or whatever. So that should help if it is a bug problem as far as killing what’s on/in the top soil of my pots.

I'm going to stay posted. If I figure it out I'll let you know. I checked for bugs too and I see no trace. PH fluctuation is my suspicion.

I get it, when i had that i seen nothing bug wise, but those lil brown dots at first, thats what i had. But i never seen one...
