Hello growers,

Id like to ask you for help with my "office grow" once again. Form first:

What Strain is it? Chronic
How Many Plants? 4 ladies
Is it in Vegetative or Flowering Stage? Growth
If in Flowering Stage... How Long? 14 days
Indoor or Outdoor? IN
Soil or Hydro? HYDRO DWC
If Hydro, Reservoir size? 8 litres of water
If Hydro, Reservoir Temperature? 24 celsius
If Hydro, what type of Medium? Hydroton
If Hydro, what type of Setup? DWC with dual 3.6W air pump (1 stone on 2 outs)
Size (Wattage) of Light? How Many? 1x 150W HPS
Is it Air Cooled? Yes IN + OUT
Temperature of Room/Cabinet? up to 30 Celsius
RH of Room/Cabinet? 25 to 30 %
PH of Medium or Reservoir? 6
Any Pests? NO
How Often are you Watering? Full dosage, then pure water to maintain level, once a week or 2 complete change with full dosage
Type and Strength of Fertilizers used? Advanced Hydroponics - full dosage, for growth phase
Size or Square Footage of Room? 0,6 x 0,6 metres
Roots Nice white healthy no smell

I don't remember this problem with my previous growths. Plants usually look good in the morning but in the evening plants look droppy.
I also have to mention that clones were put into DWC in rockwool blocks.

Should I keep water level in DWC lower to have rockwool cubes dried in pot or can it stay wet? Previous growth I put clones straight to hydroton without any rockwool so I don't have a clue if this can have a influence.

You can also see stains on some leafs. This was probably caused by too high PH and calcium deficiency. After correction this is not spreading anymore

What also came into my mind was the low humidity could cause this

Thanks for you help

Just made an emergency
- removed portion of hydroton from the pot the let rockwool cubes dry out a little
- lowered water level as much as possible
- added second air stone

cos this looks to me like "overwater"
