Hey everyone, hope all is well. Got a couple plants and noticed some yellow leaves at the top about a week ago, looks like K or mag to me. I transplanted them a couple days afterward so hopefully that will resolve it but as of now its getting worse.
Details:
6 weeks from sprout
Temp 80, rh 55-60
Light is at 24", ppf 450-500
Medium is ffof with some ewc and 1 tbs/gallon of soil of dr earth veg dry fertilizer. They've been transplanted into 5 gallon with same mix but 50/50 veg and flower as i planned on flipping in a couple days.
Using tap water, ph is 8 so I mix some filtered water down to 7ish, not sure if that's necessary.

Really just looking for some opinions on what this is and if what I'm doing is the right course before flowering. I usually wait too long to ask for help so figured I'd ask now before it gets out of hand. Thanks for any help.

I wouldnt flip em looking like that. Your mix sounds fine, so maybe watering issues?
Otherwise i would just let them settle into their new pots n soil and see if they get better. 6 weeks from seed are still babies

I usually wait till they show sex before flipping to flower. Most grows it is 8w to 10w from seed, sometimes longer

If you just up potted, then you need to let them adjust to the nutes in the soil. Looks like they are having trouble uptaking your nitrogen. What Ph is your runoff?

FFOF should have plenty already to get you going for couple weeks. You've then added ewc + dr earth fertilizer as well.
Seems like too much to me.
And, what are the directions on your dr earth? Does it suggest mixing the veg and bloom together?
I'd be sticking to the instructions.

I wouldn't be trying to correct a deficiency right now, as you've just transplanted. And, it would seem there's lots of fertilizer already.
Plain water with runoff for now.
Not worth making the switch to flower until under control.

"Light is at 24", ppf 450-500"
Have you tried backing it off just a tad? Dimming or raising it.
I think it's overfert myself.

When you noticed yellowing at the tops about a week ago, had you recently fertilized, lowered the light, etc?
Had anything changed?

I hope they're not overfed, should have stuck to top dressing if that's the case.
Only plain water so far, no other fertilizer. I'll dim the lights some and see what happens.
Thank you for the help
