I recently came across a science exhibition written by Sam Guss. It explains how wave sounds reflects on plants

@moshmesh what i did was feed the cube every five days, and then i had paper towel under it to suck the extra water out. This also helped the roots to come below the rw faster or if you can get it on a auto feed. I think @tobh said 150 mml which was good in my opinion.

one can calculate the volume of solution that needs to be ran through per grodan's instructions fairly easily. just figure out the volume of the cube in ml, then multiply it by 15% to get what you should be feeding. i forget the exact #s grodan recommends, but they're on their site.

what nutes are you running again? Looks more like a burn.
Burns were from the time that i ran the co2. heat got up to 96f and got some leaf burn, but to answer your question im running mega crop two part. A at 54.6grams which holds all the PK and more and then Part B at 23.40grams which holds nitrogen and calcium. Also, my rez is a 15 gallon but this calculation is on a 13gallon. More water mixture

I think because the x99 tall branches were closer to the light it got the burn during that time.

Basically Jack's.. I'd be surprised if you were K deficient running your part A @ 3.6g per gallon.

What happened with the CO2?

ya, very similar to jacks.

What happened with the CO2?
i'm not to sure, but i have a feeling that due to my return line going back into the rez is causing the deficiency. However, it is very minor.
The heat stress along with the deficiency made it bad. Still have the co2, but i need a fan outlet to make sure that the temps stay consistent when the doors is closed. Sealed room makes the temps go off the roof. I also need to figure how to get AC cold air into the room without having the big AC machine in there.

Kinda have a bit of adjustments to make to the room before i can run the co2
