@Tinman. Personally I’d check ph and tds numbers of runoff to get a better idea of what’s going on.
What are the ph and ppm ‘s going in ?

Haven’t really checked tds , ph is usually right around 6.4 going in, haven’t checked run off yet either, i’ll check runoff next watering

Oldguy is right on track. Those numbers will tell a lot. The other plant in pic far right back has some issues too because leaves look like they are starting to curl down toward soil. Ph is most likely outta wack cause some deficiencies but could also be off because they need nutes.

First questions I would ask too. Also wonder if they are touching soil any when fan blows across them? For whatever reason that makes leaves ugly.

You are right ,The one I pulled was touching the soil, thanks , probably going to give them some food here shortly, switching from fox farm trio to general hydroponics

Imo if you’re going to gh you should look up Lucas formula. I have never used gh, but the members that do and use Lucas formula always seem to have it dialed. If I had known you were looking to switch, I probably would have recommended Jack’s 321. Its powdered but goes a long way and easy to use.

Is that your runoff?
If so, ppms are way too low.

No, its of the food
Is that half dose? Seems quite low for bloom feed ppm.
Yes, half dose
@Tinman
You really need a runoff reading of ph and ppm to see where you are at.
I’ll do it tonight and see where iam at

Cool
Let us know. I usually adjust appropriately right after. My best plants came from when I had the time to pay this close attention and feed appropriately immediately after.

Ok bro… time to at least double your feeds. Heaviest on the bloom nutes.

I agree, unless your runoff numbers are extremely high you should probably be feeding a lot more.
