Welcome! I am no expert here, but looks similar to when I had a phosphorus deficiency. But before you go trying to treat for any deficiencies, you really should invest in a ph pen. You can get an inexpensive one. You should measure ph of water going in (after adding nutrients) and also do a soil ph slurry test (google it for instructions) first.

Yes that ph pen is very important i found out the hard way a few days ago to check even a working pen and make sure to pick up some ph solution that way if your pen goes down you got a back up method your ph is the key to allowing your plant to use all those pricey nutrients your feeding it

If you get a cheap one, calibrate it often. Mine loser calibration in the middle of mixing nutrients today. Luckily I caught it.
