The Blueberry Kush autos may be in pots too large and also have 12/12 from seed, so have not performed as well as my GSC on 16/8 in less soil, the air temperature in Ireland is about 8 degrees celcius, and indoor it is 14, so they are battling the elements, Today I will introduce a 1.3kw blow heater and feed them warm water with there Bio Grow.
my soil is homemade, a blend of Irish peat moss and worm compost with blood, fish and bone meal, dried seaweed, chicken manure and epsom salt. Perlite is less than 5%
The week of plain water last week had no real impact, they are still very dark green, I like to lose a bit of nitrogen in flower, I may use half a dose of bio grow next feed.
