Seems like you might need to get back to basics on this. 1st thing I noticed was that you have no clue of your temps, the ph of the liquids you are feeding, or the light requirements to grow your cultivar. If you go to the guides portion of ILGM all of the information you are currently lacking will be found there. A good 12 hrs of reading should handle most of your knowledge shortcoming. Next I noticed the composition of your soil. Looks to be more wood chips then anything, maybe a good soil, I dunno, seems like maybe not though. Lotsa people use lotsa stuff but, when your new, tried and true should be your thoughts so look to Fox Farm or something that has been used by millions, millions of times over so that there are no surprises, IMO. Something that helped me in the begining was the idea that less is more. In the beginning the plant is so small that a thimble of water might drown it, so mist, not water (less v more). You can give it nutes but less is more so no nutes till there is more plant to feed. Lastly I noticed that you kinda jumped in without having your ducks lined up. You said, just a guy tryin to start with what he has. This in itself is not ideal. You are acknowledging off the top, that you do not have what you need. You can try to cut paper, but if you only have your fingers to cut with, then trying isn’t what you are doing, failing is the goal you would be attempting to achieve if you attempt to cut paper with fingers. Now for the good news: this place is full of all the answers you seek, if you cannot save your sprouts with the help of this forum, you will learn why and have a better chance at success next time. Good luck!
