Phrag Kovachii drooping

[Jaxx10]

Hey guys,



I have a Kovachii for 2 months still in original media of rock wool. I noticed the last couple of days that its leaves (it has about 5-6 leaves) starting to droop/limping sideways especially its most upper leaves like if the base cant hold the leaf. I keep it in a cool, bright place place, sitting in a little water and flush every week. fert monthly and add kelp too. I did water it last time with epsom salt instead of fert.

I am waiting on lava rocks to go S/H as well.

NOTE: my other phrags are doing ok... its just the Kovachii

as always ...THANK for all your advice and comments
