I started growing medical cannabis for my son and I spotted some problem (maybe) with one of the blueberries. The problem is on one leaf and also its strange that it has some strange straight lines (like cuttings) on the leaves.
Here are the leaves: please advice if this is ok or its some kind of decease? Thank you all!
Some additional info
Soil grown Terra canna. Lights are 4 cfl 23w philips and 1 led bestva 1200w.
51% humidity and 22-24 Celsius.
Plants are around 3 week old.
This strain is Seedsman Blueberry feminized. I also have planted Girl Scout cookies autoflower, dinamed feminized, candida feminized, and diesel autoflower feminized. There are almost 20 but will reduce the count soon. I have 2-3 rooms where to grow them.
So far no CO2 generator.
Ventilation is good and I have 2 small fans blowing around.
My other equipment is:
2 bestva 1200w led
1 meizhi 600w led
1 meizhi 300w led
1 znet4 300w led
However I plan to buy 400w hps to have additional lights.
The temperature control is currently difficult, because I am for treatment of my son in Germany and we are doing radiotherapy. My cousin is taking care of the babies and winter is comming and the temp control gets harder.
If you need more info, please advice
