I've got beautiful buds forming. Even with the exhaust fan the tent stinks .
But I'm getting lots of yellow and yellowing leaves. All my plants and fed GH Maxibloom, Calmag, and Beastie Bloomz. Each watering and feeding is pHed to 6.5. I'm in day 54 of autos. Is this a natural occurrence as the plant reaches maturity, or a deficiency?

Any thoughts.

What media are you in? What kind of water? What ec or ppm? Pretty sure you don't need any bloom additives with maxibloom. I am guessing they are locked out.

Soil? You should probably be giving them some.water in-between feedings.

Coco? You should probably get the pH down to around 5.8-6 or so.

Soil is FFOF amended with perlite and myco.
Water is tap. Light is 1000w HPS, exhaust vented, tent temp is 67-74*.

Again, the buds are thriving.

How close is the light? Is it bleaching the leaves? I definitely would not be feeding soil every time. Maybe once every 3 or 4 waterings. I'm guessing with tap water, you probably don't need the calmag. Also, after adding just the maxibloom to your water, what is the ph?

Light is about 20" above the tallest cola.

I pH my water right from the tap, after I mix in the Maxibloom, and again to adjust. My tap pH usually runs about 7.1-7.5. After I mix in Maxibloom it drops down to 5.2-5.5. I'll add pH up, and bring it up to 6.5 before feeding.
