Yellow wilting seedling

Hey all,

I am having a problem with one of my seedlings, attached is a photo. It was doing great and took a turn for the worst. The top is still green, but bottom leaves are turning yellow. Medium is 35% Ocean Forest, 35% Happy Frog 30% Perlite. Avg. temp 75 degrees, I water about every 2 to 3 days. 600 watt light. Other plants are doing great in same environment, all same conditions. Thanks in advance for the help.

Exactly what model light & how close?

1 gallon bags?

You might have it too close and/or you may be overwatering.

lights: iPower GLSETX600DHMCT6XL 600 Watt HPS MH Digital Dimmable System Cool Tube Reflector Set XL Wing Grow Light Kits, 600W, White, 18 inches from canopy
5 gallon fabric bags

Your likely overwatering. 2-3 days sounds heavy for a small root zone in a 5 gallon.

pics of your other plants? Are they bigger?

Temps & rh?

You might want to move it to a Solo cup. Then get a couple CFL's. It's a BABY for God Sake!!!

here is more photos of setup, it seems to be a common deficiency if you look at the other seedling which is now growing again despite the yellow drooped initial leaves. I do think I had an issue with the roots not being able to break through the netting of the peat pellets. I ended up removing the netting completely from the two struggler's a few days ago. After that, badPlant2 started developing new leaves. badPlant1 (original img from this post), is still struggling. I also want to note that all 3 were planted at the same time, same environment, same everything.

Temp avgs 75 degrees, just did a PH test of water and is 7.5

Is this a common symptom of to large of a container?
