I have 6 blueberry indica clones . They are growing in bat mix .I am feeding them on canna nutrients a+b, pk13/14 and canna boost once a week . I give them water inbetween ph 6 6.5 .
I am using a 2 x marshydro sp3000 on 75 percent power. about 22 inches above canopy.
My grow room is 3x5ft. I have a 4inch exhaust fan and a 16inch ocsilating fan. The temps are 25 to 27 during lights on and between 17 and 19 during lights off. Humidity 60 to 65 ..
They in the 4th week of flower . I have checked the ph on the run off after watering and it' comes back at 6.5.
I have give them calmag once a week since watering (0.5ml per liter)
This week they have developed tiny brown spots on the fan leaves and also on some of the sugar leaves The spots are more to the tips of the fan leaves and some leaves are going yellow . All the 4 plants have the same problem.
I have been trying to find out if it's yellow leave septoria or calmag deficiency. Or any kind of fungus due to high humidity or too much light .
if it is septoria can I use anything to stop the spread which wont hurt the buds .
Also this is my first grow .Do they look ok for 4 week flower .
Thanks in advance
