Early seedling problem

I used to get bags of HF that were actually a bit hotter than my FFOF oddly enough. And based issues on bat guano. I followed a solution from a grower named KOMA ... by bumping ph to 6.7-6.8 it seemed to temper better. HF also begins petering out after a couple weeks and will need to be fed or ammended.

IMO i would transplant them anyways since the tap root more than likely hit bottom and is starting to circle by now. If using HF as host medium ... dig hole big enough to plant that solo “ plug “ BUT add a small scoop of Recharge or similar Myco ( great white ) into hole first ( or dust roots of solo ) before planting. A little water to temper any shock and you are gold. Myco bump will temper transplant and start to convert elements in soil for your plant to quickly utilize. You are also showing some calmag issues too ( common with led grows ). Keep light at 18” ... to control any stretch.

if they always do the same thing, maybe try something different? Try a different soil, see what happens. I’m using black gold as I did last grow. Only my second and it’s working fantastically. I always hear about this fox farms stuff, too much hype and I hear too many problems so no thanks. Good luck though!

Don't be afraid to water your seedlings. I know there's a fine line between over and under water when the plants are this small, but for sure you don't want to make them beg for a drink. Also, spray your larger girl with some Epsom salt...you need the Mg. Good luck.

Go to walmart and get a humidity dome with the t5 light. It's the sun blaster brand
