Its my first ever grow. I’m not doing it in a permanent location but I have it setup in a small attic room. I moved the plant from its solo cup into a 5gal planter about a week ago. I caught myself overwatering it so I did not water it today. I added nutes on Monday and now I’m noticing single black spot on 3 leaves and the tips on a couple are yellow. I don’t know if I need to add Manganese. I also know my ph is bad i need to get ph down for it. Thanks for any advice

Being your ph down, calcium may be getting locked out.

You can use Lemon juice to lower ph, Happy Frog soil should not need nutrients for a while(not sure how long). You need to test runoff to determine feedings. PH pen and TDS meter almost required for indoor.
