Yellowing leaves, time for utes?

My plant has really started to get some yellow fan leaves. Have yet to use nutes for flowering and im about 3 weeks in. Is it time? Anyone suggest a good flowering nute? Foiler feeding is an option too...

If you want to see a ton of yellow leaves, check out my balcony grow. I'm the master at growing yellow leaves. For the most part, it's because I waited too long into the grow before adding nutes. I gave it a lot of bloom nutes, which didn't stop the leaves from yellowing.

More importantly, yes, it is time for you to use nutes. Have you been giving it nutes while it's been vegging? If so, what kind? If you've never used nutes before, then your plant is low on Nitrogen, among others. Bloom nutes are also low in N. I would suggest getting some bloom nutes, AND some fish emulsion. Start with the fish emulsion to get plenty of N into your plant. I would try that first, then switch to the bloom nutes.

Got pics?

Im doing an outdoor grow should I be giving my plants nutes because I see yellow leaves towards the bottom but upper part of the plant its all green and a lil purp on

I was actually thinking of going organic, i would feel alot more safer. Perhaps bat guano? Anyone know if its available at lowes or home depot?
