Hello R2R peeps!

[RudeDawg]

I bought a frag of UC Amazeballs back in February of this year and it has never opened up for me. I do have two other gonis that are doing great. One is a glitter bomb that I grew from a tiny frag that almost didn't make it. The other is a Hollywood nights that's growing and has great extension. I'll include images for reference.

I started dosing a drop of manganese 3 times a week because I read on r2r that it helps gonis recover? I must confess that I'm doing it blindly with no icp testing or knowledge of how much should be dosed. So far, I have not seen any improvement.

Looking for advice on what I can do to help the goni open up. Thanks.

I do a 2-3 gal water change weekly and dose afr.
