Bottom leaves turning yellow!!

So its kind of hard to see exactly what's going on in these photos because these two particular plants are hard to get to to to take pics of. What is going on is that on only a couple plants some of the leaves at the bottom of the plant are turning yellow and a couple have gone completely yellow. I have 43 plants and they all look great except the bottom leaves of those two (so far). I just started the 7th week of flower, I'm using soiless with flora series and keep the ph level at 5.8. I water every other day doing drain to waste, they all get the same nutes. I'm hoping all it is is that the plants don't need those leaves anymore due to them being toward the end of their life cycle, would appreciate some input on this. Thanks

By the way, sorry for the pics being sideways.

Do you want a real response or are you just showing us that you have 40 some plants

Are those two different strains then the rest? My guess is they may need fed more then the others.

Prolly gonna b OK cuz Ur nearing the end of the cycle.

plus one....

They are all the same strain and they get watered individually accordingly.
@Keysareme-of course I want a real answer why would I waste my time just to tell you I have 40 some plants, I put that in there as a reference to how many were doing this compared to how many I have.

Your in the 7th week of actual flower.

Leaves help the girl eat, and they burn out as she nears full potential.

Yes just started week 7 of actual flower. It's a 10 week strain.

You are beyond good brotha.

good info def leafs get yellow or fall off just before harvest..

nice great work, can't wait to see it advance.

Right on good to hear

I'll keep you posted on what ends up happening but at least for now I can put my mind at ease. Thanks

You don't want any yellowing until the last 2 weeks. It will still be ok but it could be better.

If your using chem nutes then I'd start the flush. Don't completely stop nutes just slowly back off.
