What ph tester should I buy

I'm new to growing and I want to buy a digital ph tester . Which one is good for growing ,? Thanks .

Blue lab imo but honestly do your self a favor by a gh ph drop kit and save your money for other stuff or a ppm pen which would be a better buy imho

Or a combo if the cash isnt a factor but you will need ppm assuming you don't have one

I don't have either , what brand do you recommend ?

Blue lab meters or pen but like i said i personally don't feel the need for expensive ph tester when drops are easy enough and keep loot in my pocket also drops dont need calibration

I've been using the drops to check my ph but I can only check the ph of the water before nutrients , after I add nutrients I have no idea if the ph changed , that's why I was thinking digital .

Test your nute water the same way you should be able to tell i test feed and run off with drops no issues but my nute mixes are weak

Nothing wrong w digital just like to keep things cheap where possible
