WTF!!! I got the pH down this morning at around 2AM when the lights were off, I wanted to see what the temp of the water was w/o the lights. (74*) Today, at 1:00PM the temp of the air was still 84*, the humidity was 50%. The water was 82* and the pH was BACK UP TO 8.3!!! The water has bubbles on the top, I assume from the nylon. The water also has a milky, yellowish tint to it. Don't know wtf that is from. I still have not added any nutes since the first day when I added ROOT66 and thats it.
I have no idea if you are in VEG or BLOOM or how old your plants are.
I do not understand why they are not being fed some nutrients. You water temp is way too high.
Questions:
1-Should I flush the water out and add fresh water? Yes, Once a week.
2-If I do flush the water, should I clean the reservoir out completely?
I clean mine about 80 to 90% , but not 100%.
3-Can I use baking soda and vinegar for pH up and down?
YES, it is not the3 best for all the time, but will work.
4-Should I adjust the new water in the reservoir with all the pumps and stones in it?
YES
I've been reading both of Rosemans tutorials, the one he started in August and the one he started back in 2007.
Please help.
