Water
Is it bad to make my water ahead of time ? I mixed my nutrients (big bud, formulex, bud candy & molasses) in with the water & have let it sit out for over a day. I heard letting it sit out gets the chlorine out (I put a towel over it though so my cat/other stuff would get in it)

Does anyone knows if should I flush the pot ahead of time to reduce nutrients levels?
As you can see from last pic from week 6, I have used pre amended soil with 2.5 % of Nitrogen on dry mass. (sorry for the italian). Should I flush the pot ahead of time in order to reduce nutrients level so to both solve the yellow tips problem and favour the flowering stage?

Canna boost and autopots
HI! I have a question regarding Canna Boost and autopots. Do you use it in a reservoir? The ph is rising faster in res since I added it. The nutrient solution in res also got cloudy and trays became slimy. Since I use airdromes the ph also rised too much.

FOAM in the DWC tank
Hi guys, yesterday I changed the solution in DWC and today I saw some foam in the tank. I had some ph oscillation and used first ph down and after some silica to raise ph. I guess that could cause that foam, what do you think? Some tips?

I flushed with 16L of water for nitrogen toxicity. Going forward I am going to continue using Sensi Bloom nutrients and I am wondering if it would be beneficial to just use Sensi Bloom part B since part A is an NPK 3-0-0.

How dark is too dark?
Are these looking too green? I’m not seeing any N-tox clawing but they are pretty dark, growth is pretty vigorous and steady though so I don’t know. They are in a pretty rich organic medium.

High ppm in drainage
I flushed coco two times with 8-10 litres with CalMag (200 ppm) and it does not help. You can see in my comments to the last weeks of the diary that it doesn't matter how much ppm I water the plant, it is always 2-3 times more ppm in drainage.What should I do?
