The leaves aside from the pinholes look fine. Everything else looks fine also which is what makes me question what exactly is happening. No leaves are yellowing or showing any other sorts of deficiencies. You'd think the fastest growing plants would be the first to show but they all seem to look fine. Between this issue and the GSA, I'm kind of at a loss. The only logical thing to do is make sure I don't do anything drastic, and don't expect results very quickly. I'll switch over to dry ferts on Sunday which is the start of the dosing week and see how any new leaves look as they grow in. Temp and CO2 have both been stable so I can rule them out right away. I raised the light fixture and cut the peak cycle back one hour so it'll probably be a couple weeks before I notice anything from just doing that. I really wish they made a freshwater potassium test kit. They did at one time years ago, but I haven't been able to track one down recently.Don't be mislead by pinhole info related to low K. Many deficiences look similar for a variety of reasons. If your dosing those levels with KNO3 and KH2P04 I doubt you have a K deficiency. Granted every tank is different, but I don't even dose K separately and have a ton of BUCE with no deficiency. Are the leaves on the Buce normal looking other than the pinholes?
