So after replanting my girls into a 50/50 top soil perlite mixture, everything went good for 4 or 5 days. Then this started.
Mg deficiency?

What nutrients are you using? How strong you mixing them? How often do you water/feed. Were they rootbound or stressed before you potted up? Looks like a magnesium problem. I say problem and not deficiency because it might be another reason but whatever the reason its not uptaking enough magnesium. Could be simply not enough magnesium, pH could be out of range or could be from salt build up. I would guess since it started after transplanting its because there's not enough magnesium in your soil. But need more info.

Sorry for the lack of info, I was already
and on my way out the door. Fox farm nutes at regular feeding strength (should try half?) every other watering. Watering ever 3-4 days (pots are small) Just checked my PH and its 8.0. Gots some ph down today and I'm gonna start with that. Plants where a little stressed because I had them in MG before but not root bound. I guess I was looking to make sure I am on the right track. From what I've read, my PH could be locking out the nutes and not necessarily low mg levels?

hellos. I may be wrong but isn't magnesium def supposed to affect new growth? bye

It's not mag anyway, doesn't look like mag, maybe boron or a combo of boron, iron, ... from the 8.0 PH.
Mg def appears on older leaves too. Looks like mg def and perhaps general def from either too little or too much nutes (salt build up). OP would need to compare the amount he feeds with what other FF users feed. I'd recommend watering/feeding for 50% runoff. But, I'm not sure if that should be with milder nutes or stronger.

You are wrong! Dead wrong. Because magnesium is mobile the plant will take it from older growth to give it to the newer growth... exactly whats happening in the photos. Don't spread bad info

IF it's magnesium, a bit of epsom salt will clear it up. Add two grams per gallon to whatever regimen you're feeding with and see what happens. This is a relatively light dose that shouldn't cause any other issues.
Get it at your grocery store, in the pharmacy section. Often, the labels themselves tout the benefits of using it as a fertilizer.
The sulphur is beneficial, too, in the production of terpenes.

Nice chart. Where can one find it? Great reference tool.

I just take a big pinch using all my fingers and it seems to be about the right amount per gallon.

I had a small laugh. I think he might mean a larger copy or a poster. Just a guess. Definitely a handy little reference.

Honestly, if you don't have a gram scale laying around somewhere, I'd say you're in the wrong business. Or do you weigh out your bags using 'a big pinch' method, too?
Getting an eyeball on the correct amount verified by instrumentation is an important step in calibrating one's 'pinch'.

Yeah it helps. I measured the ppm I was looking for actually using this method. Didn't bother weighing it. I just sorta know. Never have issues with it. I measure the first time and then basically go by feel after that. I basically just add water anyway.

Epsom salt is pretty forgiving that way, especially in soil or soilless setups.

A. It worked for me without any trouble. Check your settings.
