Leaves Yellowing

[Midnightfarmer]

The plants getting older but not ready to harvest. Some of the leaves started to yellow last week and now more of them are. When I feed (Flora,. Raw Sweet, Cal-Mag and other) I check the PH which I keep between 6-7. Today I checked water coming out which is between 4-5. Should I raise PH going in to above 7. I really don't want the plant to prematurely dry out. Suggestions please

As the plant matures, all the energy will be used from the lower fan leaves and they will be the first to yellow and die. Just another indication your plant is ripening just fine. Maybe its time to start the flush?

Problem is they are the top leaves and buds are not full yet. What concerns me is water coming out at 4-5 PH

Using Happy frog and COCO Water and nuts going in between 6.0-7.0 Water coming out at 4.0-5.0 Should I just raise PH going in?

No..keep ph going in at 6-6.5
