Yellowing leaves

Not sure what's going on here. I have some yellowing leaves on some growth around the top of my plant and have been getting some yellowing leaves at the bottom. I have two super lemon haze going and one is growing a lot faster than the other. The one with the leaves yellowing around the top is growing fast. Whereas the one with the leaves yellowing at the bottom seems to be creeping. Can anyone point me in the right direction?

Set up and feed type, schedule info plus any other relevant data like PH, EC/PPM/TDS, when did this start and why do you think it is happening, please.

Setup, 5 gallon smart pot in fox farm ocean forest under Mars hydro led lights.
Schedule, 18/6 being fed every 4 days or so with r/o water that has been pHed to 6.5 with a tsp of Cal/mag per gallon of water. Fox farm nutrient trio every two feeds at half strength.
Upper leaves started probably 2 wks ago. Maybe a little more. Bottom, just within the past couple days
My guess to why this is happening is either, needs nutes more often than every two feeds.

Ph issue

My pH is 6.5 and even the run off pH is good. At first I thought the same thing. But after double checking the pH I can't agree. I have two different pH testers that I use to be certain. Or should I power the pH? Or maybe raise it?

Top coat with a little dolemite lime and see if it doesn't correct, worse case scenario you prevent gnats, best case it helps buffer the ph levels and she can uptake the phosphorus in the nute solution better, 6.5 is the high end of the spectrum I believe

OK. I have some dolomite lime laying around so I will do that. For future reference, how do I prevent this from happening? Maybe lower the pH to 6?

If the dm works and you have it around just always amend your soil with it at the start and it won't ever be an issue again:peace:
