First timer, doing well so far, need feedback and some answers, thanks!

My first plant is an autoflowering afghan kush - day 30.



Questions:
when should i start bloom nutes? how many weeks should i have quarter strength, then half, then full?
what to do with the yellowing leaves at the bottom? cut off i assume? if so do i just cut at the stem?

any advice is welcomed

second plant dinafem grapefruit - day 30.



any opinions on this lil guy, not really my primary concern atm

thanks rep will be given

You don't need to do anything with the yellowing leaves on the bottom. The plant grows and sheds leaves naturally, so you don't need to worry about them. I'll leave the questions on nutes to someone else. I don't grow autos, so I don't want to give you misinformation. Cheers.

PS: Your plants look happy!

Don't cut anything, they will fall off when ready to.

1/4 strength to start is fine if you want to be safe but really it depends on what product(s) you are talking about.

edit: sorry didn't notice you had autos. I never grown autos but I'd think you'd start bloom feed at the first signs of flowering.

The website i brought off says only 17 days of veg, then straight into flowering, thinking of starting at a quarter strength this week, moving to half strength next for 2 weeks, then to full strength.

thanks for the help, rep given!
