So a lot of you were right when it came to what was going on with my plants. I am low on potassium. I'm at about 10 parts per million for potassium. I'm aiming for something from from what my test shows I need to aim somewhere between 15 and 30. Right now I'm using aquarium co-op, easy green, all-in-one fertilizer. I'm dosing about 4 milligrams but as I've checked the bottle it doesn't look like they have any potassium in here. So I'm guessing that this is where my problem might be coming from. I'm also a beginner so I definitely can use some guidance in this project.

Fertilizing aquarium co-ops easy green, 4 ml Wednesdays and Sundays as suggested by another redditor

Reminalizing RO water previously with equilibrium but converting over to be shrimp mineral GH by salty shrimp Aiming for a TDS of 150 to 160

Any suggestions on how I can up my potassium in my tank? Good fertilizer suggestions. Knowing though I do have bamboo shrimp and a mono shrimp and looking to carry caradinas in the future so definitely needs to be shrimp safe.

Thanks all again for your amazing help in suggestions on my last post.

Additional note, I was able to get my CO2 become stable. As far as using a drop checker, I'm looking to do another method for reading my CO2. I decided to place it on a different timer so it wasn't turning on when the lights went on. It's turning on an hour before The lights turn on and turning off an hour before the lights turn off. Thanks again for a lot of help on that one I appreciate all your knowledge.
