Yeah thats what it looks like to me, as well. Either lock-out from wonky ph or a straight up deficiency. It gets out of control quickly and can really mess up yield. I can testify to that.Looks like a potassium deficiency to me

Make sure your pH is good and that it isn't light burn.

Need some help here guys
DWC Hydro setup
Seedling was in solo cup for 8 or 9 days before transfered to DWC.
Layer of pebbles and then the root/stem
Water level is above basket giving lots of hydration with no top feed
Transplanted the plant to DWC 5 days ago. This is what she looked like
5 days later she is no bigger..she is alive and the stem seems strong as she holds herself uo
Under the 1st set of leaves are the original 2 that sprouts. Thry are turning yellow now.
This is the after shot 5 days later
Water is pH 5.9
Thinking I should either add. More water to raise the water level or lower the plant further in the bucket.
Not sure on this one. Thanks!
Hey Nick, i know when i grew dwc the upper growth always seemd slow while the roots were growing and searching out water, however i always used a drip ring to top feed until the tap touched my rez, just to keep the media saturated. I also used like 1/16 strength nutes for tge first week or so until roots in rez also. My cotyledons almost always turned yellow at first until i started using low concentrations of nutrients from the get go. They use up their "starter" food they're born with quickly when they have nothing to draw from the growing media. Hydroton, lava rocks, perlite.. They are barren. She may be showing you shes starting to get hungry.
I would recommend adding light nutes and top feeding just a bit beside the stem to help her grow a taproot faster.
Just what works for me brother. I am no expert but ive had a few nice dwc grows.
Are they a good brand? If I got 1 600W I think I could get away with that for my entire grow and still have a good yelid.
What about height? Is 150cm height ok for LED use? And heat wise I'm presuming they won't kick out more than big 200W my CFL's?
I've got two 900 in my 5x5 as wellI have a 2' x 2' x 5' tall tent with a Viparspectra 600 watt fixture in it. Four weeks in my second grow with the light and tent. The light I believe is rated to cover up to a 3x3 tent maximum. It does a great job in the 2 x 2 tent.
Really appreciate the feedback. I gave her small 1/4 dose of nutes when I started. I will take your advice and do another feeding with a top feed as well. It's my 1st hydro grow and not used to seeing the cotyledons go yellow so fast with very little growth. Cheers!
Ok so in some of my reading material I've found mulch on top of your plant soil will prevent soil compacting.. so a good on for a sandy gorilla grow perhaps?Any other ideas? Id have to put so much in this sand I may as well grow in straight pearlite and go hydro.
I feel like I need some more carbon (browns) in my soil, like wood.
What is this chicks deal? Brown tips twisting leaves. Mostly in older fan leaves.
Well I've been pondering putting a elevated long flat Bin with a hole drilled and hose before it's too late. That way I can flush and remove run off.Hey you have smart pots where do you take your plants or what do you put under them when you flush them?this is my plant
