Did you bring it back? Lotsa times they can rehydrate and take off...

I hate killing these plants, will bend over backwards to revive them. Last grow, the green cracks were a bitch to get thru veg, hated them, then they got their shit together during bloom, became my 2nd fave of the 4 strains...
I sure did brother, that was the plant I donated to Hom3grown that bitch was an easy 3, 3.5 ft tall.

BTW, that looks like sulfur deficiency to me. If you're using tap water, it usually contains enough iron (which is why hydro nutrients usually don't have a lot of Fe). Iron deficiency makes the leaves and shoots look "whiter" - if that makes sense. High pH and high Ca levels (hard water etc) can lock sulfur (and iron) out. IMO, S deficiency is a lot more common than Fe.

Personally, I'd spray with a bit of epsom salts and maybe add a teaspoon for every 10 litres of nutrient solution.

More likely, they just need to harden off and develop their root system with a good alround feed.

It’s iron...yellowing of younger leaves starting at the base, moving out....overall leaf dark green...

Locked out by something else....

Take a bet each way: click

Been thru all of that...it’s classic presentation of iron deficiency, due to lockout...likely other minerals locked out too...

Sulfur is a general lime green moving to chlorosis...this was general dark green with chlorosis....new leaves...starting at petiole...

Roots are branching, so plan is short flush again, this time with ro, foliar feed, and begin dilute veg nutes.

I hate regulars!!!

Done deal, lucille...

Brand spankin new batch of ro water, bubbled for 5 hrs, temp 68F, then pH’d to 5.8, swapped with wednesday’s fill, let plants run with it for an hour or so; then added regular technaflora veg nutes @ 0.4 ec, reset at 5.8pH, then added gff.

Air temp, rh, lights: no change, 75F, 75%, 18:6, ~120 ppfd.

Time to katn..

Ordered a couple versions of these donut humidifiers, to check out usefulness for humidifying seedlings/rooted cuttings in small spaces:

That's pretty fucking wicked dude. I spot shit all the time when we're walking through a store that I could use for something or another haha. I spotted a little mesh-top table the other day and I was like man, that'd be great for a DTW coco grow...lol
