best range pH runoff
Ksouth1started grow question 4 years ago
If I water at a pH of 6.5, what would be the best range for the runoff pH to be in? I am curious what everyone else goes by. Thank you for your time and happy growing to everyone!

Runoff Ph should be witihin 0.5 pH of your watering pH. If runoff pH diverges more than 0.5, keep track of it to see if it continues to move away from the input pH. If pH continues to get lower, use less nutrients.

The closer the two measurements are the better. You want the two to be about the same which indicates the feed is balanced. If the runoff gets too out of balance, one way or the other, you adjust the feed water in the opposite direction to bring it back inline. TDS should also be measured in and out to see how much the plant is eating or if it's "full" and can't eat that much. This balance is the key to quality if other conditions are equally met.

Flushing QuestionI likely have 2-4 waterings left depending on when I start to see amber (I'm not afraid to push THC degradation in exchange for CBN, I'm actually for it). Do I use a flushing agent (Flawless Finish) my next watering and then clean there on out - or is it my last watering?Techniques. Other

Outdoor Bonsai: Root Pruning instead of Repotting?? Thoughts??I figured I would start off my first grow question with a bang:
I'm thinking about turning Barry into Bonsai Barry. So basically, put him in the 7Gal pot and root prune where ideally you would repot (I would say 2-3 times knowing that I'm early).. 3..... 2...... 1....... SHOOT4 years ago

Should I start flushing for harvest?I'm thinking about starting to flush in the near future (probably about 3-4 days from now). Based on my photos, does it look like she's ready for flushing, or should I wait a bit longer? I'm using a mixture of coco and perlite.
