How much water do you reckon my plant ought to get? With pic

[growsomebud]

Hi all, so here it is(don't know the sex, yet), it's 11 weeks into veg. It's been in this soil since day one.

I've been feeding it a gallon of water every 6 days after the top soil dries out, and I don't think it comes close to giving me any runoff. Thanks for reading.

Not sure I follow? You want to know how much water to give her, and right now a gallon doesn't give run off. So...give more water?

I've got mine in a 5 gallon fabric pot, she gets 6L every 6 days right now. Just over 1.5 gallons of water. If you're looking for run off, just give more water lol

You can give measured amounts of water until you get 10% to 20% of that back in runoff.
Keep track of how much you're adding each time and pretty quickly you'll figure out just how much you're likely to need.
An indoor grow shouldn't vary that much since sunlight, rain, and wind don't vary, but you'll probably see some variation when the temperature changes.
When she goes into stretch, that affects things too.
And the pot filling up with roots means it can't hold as much water just when the plant is getting big and needs more.
If you keep a good log book that will help a lot.

Since you're watering to runoff, I strongly suggest getting a PPM meter, a pH pen, and some pH calibration solution and measuring both input and runoff. That will tell you a lot.
