I'm desperate can't take this shit anymore!
![Confused :?](./images/smilies/icon_e_confused.gif)
This is my 4th round and every single time when I reach 4th week of flowering shit starts to go downhill.
Everything seems on point.
I have no clue what happens.
![Embarrassed :oops:](./images/smilies/icon_redface.gif)
Check the pics, the bulge begins to halt and leafs necrose and die.
This is sad.
Nute is only 1.3ec, PH 6.0 on point, temperatures always ok.
Last round the room was 100% sealed with CO2 and I read about sealed room phantom issues, so I decided to vent every hour even though it increased my CO2 expense. Thought it would be ok, but nah, same outcome.
Substrate is Sphagnum/Perlite 50/50.
Watering once a day until runoff, containers 7L.
Lighitng is 2x Fusion Boards for a total of 150w only. So can't be light stress.
CO2 was running at 900ppm, but at first sign of issues I left at ambient (350 to 400) to no avail.
runoff = 5,3ph 1,0ec
feed regime:
Jacks 321
RO Water.
Only known issues:
Some bugs on the soil, looks like gnats, they're so small I cant catch them or photograph them. Not huge infestation, maybe some kind of bath fly. Can't be sure, however what I know is last round they were not present but the issues were the same, so can't blame these bugs for the current outcome.
I'm out of ideas. Need help!
