Lingering Isuue that must be resolved

Also, the problem starts in the middle of the plant and works its way up

I'm not watering to run off. My water is straight well water and I do not use ph up as it will kill microbes. How do you suggest I up my ph organically and at what rate?

Too much water doesn't Exist.. I grow hydroponically and the reason it grows so fast is because of all the Water.. And air.. Air is important. But overwatering has more to do with a lack of drainage and not paying attention to ones plants.

Your foliage looks awfully dark.. It could be lighting.. It could be the super good smoke I have access to all the time.. Tends to SKEW my point of view but I agree with the other person about watering in Soil.. If your soil is peat moss based it will be Acidic.. If you buffer down your water before you add that.. Then the buffers get left in the soil and drops your ph even lower. The Advice is sound.... Save some money.. Don't buffer down your water. Unless your in Coco. But if your growing in Coco TDS/EC is super important so I am betting you grow in soil.

Ph is way too low in my opinion for soil, should be around 6.3-6.7. Also when I am growing organically I don’t actually water to run off and my water is around a ph of 7.6 and I don’t ph balance it at all. Feel free to check my organic diary.

I am growing in subcools super soil recipe this grow which differs from the 2 previous grows yet I'm having the same issue. Also I just had a fungus gnat issue which I resolved with diatomaceous earth. Had gnat issues with last grow as well. Too much water maybe?
