its basic garden soil with ph around 7, it was in sack kept in storage over a year, probably I will get new soil and transfer them there, I have grown in this soil and never had a problem….
this was my first time growing and I don't think I would use the styrofoam cups anymore. I'll be surprised if they make it the roots were bonded to the cup so strong.
repot into new soil dont feed just water till plant shows signs of being hungry lower your ph to 6.5 for better nute uptake as a ph of 7 is not ideal for uptake take a look at this ph guid use the one on right as you can see you just not getting the right nutes id lower to 6.5
