Hello wondering what I’m doing wrong here. Help would be appreciated. I thought was micro nutrient issue so I put tm-7 on soil and some earth work casting. Didn’t change.

Ethos multi pass seeds. Used black swallow living soil and promix as a medium.

I then figured out my ph of water was 7.2-7.5. So I lowered to 6.2-6.5ph. It’s been a day since I changed the waters ph and there hasn’t been a Positive change. The leaves are folding at top like a taco. I found aphids two days ago so been using plant therapy at night. I have been weighing the plants and they been using around 1lb of water each day. So been giving them top up daily and bottom feed of just water to replace what’s lost. (1lbs ish water)
Rooms temp is 23-25c. Humidity has been 63-64. Leaf temp has been 23-25c. I have one large fan oscillating constant air.
Lights at 40-50% at 4ft. It’s a 650s optic led next gen. Red uv ir has been set to lowest option of percentage.

It’s living soil I use just water. But I used molasses last week with water to help feed microbial life.

Should I just keep watering no nutes till the new growth is back to normal.

Any help would be great thank you.

If your other parameters are good, a pH problem is a reasonable guess, but it's unrealistic to expect to see a visible change in a day.

Pro mix has buggers that PH balance. As does most soil it is rare to need to PH fresh soil. Those look fine man new growth is ama so lighter green.

Hey bud it’s like yellow and dying and curling and folding like a taco. That’s not normal. Would high ph at 7.5 cause this issue?

Folding leaves like a taco isn’t normal?
Neither is so yellow that it’s curling. I’m confused why you’re trying to turn this into an issue when I already have one?
But thank you

thar isn’t yellow dude that is light green totally normal for new leaf. Also taco it is likely slightly hot but judging a new leaf is alloy man. It can’t be PH soil has a buffer as I explained. Look you be better listening and not arguing when you ask questions. Good luck.

that is t yellow dude that is light green as is all new growth. New growth is light green that is normal. Your brand new leafs need a few days to get green and stop taco. That is why all the issue is the new leafs. Unless you see full size leafs you are totally fine. I don’t even need to PH at all with almost all soil. They have buffers that do it. Maybe if you are reusing long time I have pro mix hp indoor and fox famr
Outdoor and neither PH.

Thanks bud. So basically just water keep ph around 6.2. Don’t do anything else see if it improves?

No idea, I only grow hydro.

In general, it's not a good idea to mix mediums. If you wanna grow in Pro-Mix, grow in Pro-Mix. If you want to grow soil, use soil.
Mixing the two is not the "best of both worlds".
Pro-Mix is acidic by nature and has lime added to raise the pH to reasonable levels. As the lime is depleted, the pH drops.
How to deal with that when it's mixed with soil? Your guess is as good as mine.

As mentioned above, lime green new growth is not a cause for concern.

Hey it’s yellow and going white and dying this isn’t lime green. I know what normal growth looks like. Otherwise I wouldn’t be here.

I have used this mix before and never this issue. But I wasamending and adding stuff on top for dry amendments.
