Nice res change today for the 5 gallon. Running at 650ppm-50ppm. Started to add slight amount of flowering nutes too. Not sure how to drain the tub, algae is forming and it needs to get cleaned out. Looks light brown and almost powdery.
So the 5 gallon delahaze dwc looks good as always. Still at 450 ppm. I'm thinking a rez change tomorrow and moving to around 550. Internodes are really devloping well too. Not sure if I want to top though.
Day 23:
As for the 22 gallon 9-site DWC, all the plants in it seem to be showing a...
The issue that everyone is having is the fish choice. In a true aquaponic setup, they are using a large fish that they plan on harvesting for sale, such as tilapia or catfish NOT guppies or goldfish. A few guppies arent gonig to produce the 2500ppms or so that mature plant is going to require.
Well at first you should leave the water level nice and high to prevent the seedling from drying out, but once the plant starts to develop a nice root structure, you should let the water lower and have some of the roots not submerged. They'll intake air and will stay moist due to the humidity.
Day 21, for three weeks the hydro doesn't look bad. It has completley healed from the N deficiency. I didn't realize that I had to subtract the ppm of my tap water from my ppm res readings. Right now the res is at 500ppm - 50 from my tap water= about 450 ppm. Looking great. Going to veg for...
Wait you said 680EC, I think you mean 680ppm which is just under 1.0 EC. In that case, you are running way too many nutes. I just moved to about 400ppm for this 2 1/2 week old seedling
The hydro setup is looking the best. The growth started to look a little yellow, so i bumped the ppm from 120ppm to 180ppm, and now the new growth is the color I want. As for the 2 Purple Kush, and 2 Pineapple Express autos, they look healthy, but growth is incredibly slow. I blame my soil...
Most definetley is the MG. Also make sure you are watering properly, wait till it is dry and then drench it, don't just spray around the base of the seedling.
