How do i fix this?

Can you guys tell me what's wrong here!
Im growing in ffof and im using Alaska fish fertilizer. My ph is right on 7 but when I add Alaska fish fertilizer it brings it down so I bring it right back up! Im adding one gallon of fertilizer at a time and I recently changed it to 2 gallons and the rest with plain water. I water every two days since she's always droopy the third day.
Is it too much fertilizer? Some of the leafs sides seem to curl under! I don't know how to fix this?

Your tips show nutrient burn , but sounds like your over watering which could be the cause , I would lay off slightly on watering as much and get your ph down to 6.4.

Regardless plants look good and healthy!

Overwatering causes droop. FFOF is already PH buffered between 6.3 to 6.8. You don't have to fertilize so much. Spread out the watering.

Your plants look good regardless ( tip burn means you are at the border of typical burning ) . So not too bad. Just space it out a little. My fish fertilizer is 5-5-5 , so I cut it in half if I use other soils than FFOF because it already loaded with amendments.
