If so the stomata are on the underside of the leaf try not to spray that unless the method requires you to do so.

They look much better already Prosper !! Never heard anything bad about Great White. The yellowing could be the nutes or root rot. I would say add a bit of great white if you can . Just to be safe . 1/8 or 1/4 strength.
I wouldn't defoliate anything til you have 4 sets of true leaves. Colas come later in bloom. Those are just fan leafs.

Not sure about Sparkys advice. Um . Definetely don't spray any peroxide on them.

So here's today's update. It's been about 24 hours since the nute change and the water level reduction. I have done some research in what causes root rot and it can be lack of oxygen to the roots so I ordered a better air pump. I wasn't sure whether to get a bacteria powder like Great White but I'm gonna bite the bullet. I have noticed more drooping tonight in the new leaves (see image below). Again any feedback is appreciated fam.

Morning Prosper. A quick question. Are the leaves drooping all the time or only near the end of lights on?

Seems to be every time I check , I've gone from 24/7 lights on to 19/5 light schedule to give the plant rest.
How about air and or water temps. Air should be around 70 to 75f, and water around 66 to 68f. Anything to much above or below these parameters will cause them to droop.

Air and water are within those parameters. And the PH is adjusted to 5.5
I think that raising the ph is your answer but time will tell.

Naturally when the plant consumes the nutes the PH goes up and I adjust it back down once a day to 5.5 range. What should I be adjusting it to?

I’m not telling them to spray I asked if she sprayed and she does because I seen it. I said I did experiments. I would like you to point out where I told her to do this please. No reads in these forums and you just end up answering the same stuff over and over again.

Reading comp. I told to stop and identified it was being sprayed by the personwithout being Told. So read read read before commenting. Please.
A ph of 5.5 or 5.6 to start and no need to adjust down each day. Let it swing up to 6.2 or so , takes about a week but that depends on the res. size. Keeping it at 5.5 each day will starve it of nutes that aren't absorbed until a high ph. Plus the less ph down you add the better, less is more.

It was an experiment. That’s how I know what these plants are doing. I do experiments I do not trust the net anymore.
