Brown Spots Stunted Growth. HELP!

It's better to start your babies in a small planter with nutramix hp. It is a peat based medium that requires you feed your babies from the first 3 days after sprout. The first feed after the first 3 days with no feed you start feeding at 400 ppm 0.8 ec. After the first week of growth the planters will be full with roots and will be much more prepared for the transplant into soil. Babies almost always take way to long to adjust to the heavy nutes the soil has in it to begin with, then people make the mistake of feeding on top of that, which just stresses the plant to the max. When nutes are to high plants cant take the food up. If you start the way I explained your plant will thrive from the start and the 4 to 5 weeks people spend trying to get their plants started, you will already be at a good size to switch to flower mode.

To me it looks like damage from the leaf rubbing on the soil, most probably when the fan is blowing on the plant. The brown blotches are typical of leaves that have been in contact with wet soil, especially the lower ones, when during the night, the leaves droop down around the plant. Unless there is similar damage on higher up leaves, I personally wouldn't be too concerned by this. If it is REALLY bothering you, you could always trim the leaf damage off. Hope this helps...

Could be overwatering when tbey are young the roots arent has develloped. So if yiu water all the grow medium it can cause this. Reduce watering amount next watering and add 10-20 ml of hydrogenous peoxyde to help oxygenate the soil around the root and to clean the roots. . The overwagering ciuld have been done before and you are seing these results now.. it will regrow. Its just that some of the roots have been damage they are healing that why its stunt. Stuning when neither nutes or ph are related usually means root probleme. Like gnats, root rot or other thing like that. Adding peroxyde to watering help greatly for anything root related
