Tryin to figure out why? Humidity has gottin low a few times like down to 20% but since ive started usin co2 with ppm at like 1100 the humidity has gone up around 45%...will the curl go away?? Could it be sumthin else?
any curling upwards is more than likely heat stress or nute burn
room at night gets low 60's day temp is bout 72-75Low the humidity to around 30,
and how hot is it in your grow room?
Most likely heat stress.
NoB
yea ive gottin humidity back up to 45% -50% yea an im doin hydro ebb n flow buckets 2gallon with hydroton/clay rock.....but will the curl go away????for some reason i thought you said you were in hydro. sorry watching tv and typing..humidity needs to be higher for optimum growth not in the 30% dunno why youre telling him to lower it. and no humidity isnt gonna curl your leaves
