Early into flowering, yellow leave, but also crispy and curled under?

Hi there, I know this is annoying to ask so in advance thank you for taking the time to look at my post and reply, you are amazing.

So I'm about 2-3 weeks into bloom, everything bud wise looks great. But from the bottom up the leaves are going to a nice pale yellow, with some of them having the tips go brown and crispy. I was worried I was overfertilizing them, but I don't think I'm correct.

I use a standard blooming formula of 15-30-15 and have made the mixes a little weak. I do one on one off. So water, then next time fertlizer, then water, alternating.

It's in a mix of soiless with triple mix and potting soil from the transplants. Any ideas?? I can take pic tomorrow they are in there dark stage at the moment.

I get a little of that at the bottom-doesnt bother me-I just clip em off. Hope Im not doing it all wrong!!

Whats your temps? And do you have any full plant pictures under natural lighting?

Honestly on the smaller clones and one in particular the yellowing is reaching up a a very fast rate. So I'm wondering if I need to adjust the fertlizer asap.

Wish I knew to be sure.

You should continue feeding veg nutrients at least till 3rd week of flowering. Otherwise, you'll have to face losing a lot of green leaves very fast.
