Hi All, been growing for a while and had some fresh air issues so added a CO2 system.
using bio bizz all mix, grow, boom and a bit guankalong guano. growing in a weekly rotation (1 in 1 out) results before CO2 not huge but livable but as always always hunting for the bigger bud! plants that had been in for 3-4 weeks before CO2 loved and went a lot bigger, new plants are getting burnt (see pics) after a couple of weeks in and gradually worsens. had nute burn in the past and guilty of too little not too much now! all plants vegged for about 6 weeks and in at least 15-20 litres of soil.
1.2X1.2 tent
i have raised lights and dropped from 600 to 400W
vents for 15 mins every hour, CO2 released every 4 mins in measured quantity (3.5 seconds, flow rate is 17L a minute) lights on
vents constantly lights out, no CO2
temps are about 33C and humidity 60-70%
i am thinking under nuting as growth goes crazy but what? Phosphorus?
thanks for looking and any help
better pics too follow
Cheers
