Yellowing leaves

I'm on day 55. My plants have been doing great. PH is at 6.8 they are on a 12 12 light cycle and smell amazing, however, the leaves are really starting to yellow... I know that eventually happens, but I'm thinking it might be something I need to fix. Nutrients or something? Humidity is generally between 59%and 65% heat is between 77 and 81. Here are a few pics. This is our first time growing autoflowers and the first time I've ever gotten this far... I'm just paranoid I guess. I am just trying to do everything right.

Hey bro so day 55 OK so your approaching the near end can I ask why your ph is so high the sweet spot you need to be aiming for is between 5.8-6.2 for the optimal growth to occur, a safe line is between 5.5 and 6.5 but like I said aim for that sweet spot I always try stick to bang on 6 nice even number, having your pH at 6.8 is quiet high and I have been at 6.9-7.1 and have had nutrient lock out occur and ruined my entire grow

The ph has been between 6.8 and 7.0 the entire time. I don't know if it's the water here or too many nutrients or what but the ph has been that high since day 1. And for probably 3 days it was all the way up to 7.1. We are on day 63 now I believe. And I actually think we are ready to start drying some of them. Would you agree or am I rushing it?

Looks like you are doing great to me! Hang in there! Everything looks normal.

Yeah that's the standard ph for your water but you can adjust it to 5.8-6.2 with a bottle of pH up and ph down but like mandocat said looks good this far so keep with it and adjust for your next run fair play some very juicy colas there bro :bigjoint:

2-4 weeks to go, that's a respectable tap water pH mine is around 8.4 I'm hydro so I drop mine.

If they are in soil that's too low. My understanding is in soil the microbes handle your pH and most soil guys, if they pH, take it to about 6.5-7.

Thanks everyone for the advice. You'd think for a female I'd have a better green thumb but I'm clueless haha. I really appreciate the support and tips!

I'm a female and I have a black thumb. I starting growing in homemade NFT rails because I can kill anything in soil. But give me lab glass, lab tech and parameters to hit (which only applied to tomatoes when I began) and I managed to get them to harvest. You're doing much better than I did. Keep up the good work.

They look pretty. Could be a rootzone pH imbalance or possibly lack of nutrients for those particular plants showing issues. Either way it doesn't look detrimental. I would baby them until harvest and you will get a good crop.
