Ok cool. I'll just keep dumping in nitrogen until then. Once she slows down on N, do they increase consumption of anything else?
No. Slows down on everything. Keep up with P and K also though. You see some of these no till grows adding cover crops to consume excess Nitrogen after week 7-8 ish. Goes to show yea just how much soil /food has to be available to grow big plants.

Yea I've learned that now. I just need to figure out how much food and when. I'd like to not have to water in anything and just let the soil feed the plant.

Need a 30g sip or bigger I think,but still needs something.Grow smaller plants is probably the only way to go water only.

Yea, I'm thinking bigger sip also. I dunno how Jeremy from bas does it with the earthboxes. His plants get pretty big also, and he doesn't feed all that much.

Yea I need the heat.was hoping I won’t need a HPS this winter. I think I still will.
I am also worried about needing more heat this winter. My temps right now with the lights at 20in at 80% are only like 74 degrees and 69 lights out. Everything getting purple this holiday season!!! Haha

It says 1 teaspoon per gallon. Anyone think it's safe to run full strength?

Mostly water soluble so tread lightly. Maybe 3 weeks ago would have been good at full but Is do a test. Give a 1/4 and see.
Lol for sure. I have been watering in 500 ml of 1/4 strength every other day when the res empties. It's not enough apparently though, unless I should do the 16 oz daily maybe?

If you see the green fade then add more. If the green stays the same stay with what your doing. I don’t think you can get them dark green again. That would be too much.

I agree. At this point though I would like the fade to at least slow down. I'm nervous about adding it to the res. I am gonna up the rate from 1/4 tsp to 1/2 tsp and water in 500 ml. That's not too extreme right?
