Trying to figure out what this is

[KnowTheGrow]

Newb here, trying to learn how to diagnose these myself. I'm thinking either nitrogen or phosphorus? I really have no clue but I know they're wanting something.
NL
FFOF
transplanted week ago, first heavy feed a few days later. Also, fed 200ppm Cmg in RO water yesterday.

I wanted to start flower next week but then saw this, figured I'd ask before doing anything. Other than that I think they're looking pretty good.

What do the experts around here think?

Ffof is pretty hot soil and if you fed only a week after transplant could just be minor nute burn. Don't go heavy in nutes for the first couple weeks after putting it in that ffof you should be fine. Good looking plants.

Morning KTG, your plants look fine to me, nice color, healthy. Probably just now getting over the transplant.
I've used FFOF, plenty of times, never had it to burn anything, had low ph, like 5.0 an lower, an plenty of bugs ,was always our problem with FFOF.
You got some nice plants KTG, good job.

Ok thanks. I tested soil pH earlier, it was a little above 7. Was thinking maybe that could be it, but transplant with full nutes makes a lot of since. I should've waited longer but wanted to give em a dose of nutes before I flushed for flower, got greedy lol.

Is Coco harder to grow with?

[Chefbjy]

Above 7 is high for soil keep an eye on it. I try and shoot for 6-6.5 . I want to try Coco my next grow don't know if it's any easier.

Yea, honestly I haven't really been paying attention to pH much at all, just ppm. I'll flush em when they dry out and start keeping that lower.

Would y'all flower next week if y'all were me? I think I could squeeze a few more inches in (gigidy) but Idk how much more weight I'd get or if it'd be worth possibly watering daily later in bloom and getting too close to light

How long have you been vegging? How big are they? What size is the pot? How much space do you have?

Seeds sprouted Dec 22, originally I was in a 2x2 under 200w in 2gal pots. Couple weeks ago I moved to a 4x4x7 400w, 5gal pots. From soil to top...little over a foot

Probably a good time.
