It's miracle grow top soil. I have a regular garden that's had about a month old soil that i used till I got my ocean forest. But I did use fox farm big bloom at 1/3 percent you thing that done it?
don't feed em till they get a little bigger, those first two leaves (cotyledons) are actually like the seeds yolk, they have all the nutes that were packed into the seed, and the plant will eat them in its first week or two. when they start to look a little faded then its time to start light feeding
Just a suggestion from another new grower, there's a site that has a trouble shooting list. Search for it as it's a fairly good guide IMO. The site is GWE. (Abbreviation)
Still there's nothing wrong with asking here as well. I would too.
I was looking at that and I was tossed up with the hot soil or watering issues. Cause in that troubleshooting guide the pics are almost similar. Preciate it
