Stealth I agree with the rest of the group. I had an SNL x NH in a six inch pot for a couple weeks and it turned out to be UNDERFED....not OVERFED and it did better in a larger pot with FFOF soil. I say transplant to new soil.....perhaps some Happy Frog?

And while you can possibly "get them bigger" in your cups it's obviously costing you in plant health. TRANSPLANT UP!!

(worked for me and my babies.....about the same size as yours are now...)
