I just realised how stupid I am!
Last time I fed my plants, I failed my maths and used twice as strong as recommended on the bottle.
That's what's going on, nute burn. What's strange is my blueberry is the only plant not being affected and it's supposed to be a sensitive strain...
Similar thing is happening to me. Temps, relative humidity, PH are all good, plants have no reason to be struggling. I water twice a week, once with Pure blend pro and liquid karma at maybe 70-80% of recommended strength.
I'm puzzled.
Hi, this is my first setup. I have been doing a lot of reading and learning here lately! I have two 600W lamps with cooltubes in a 8x4x6.5 tent. I installed a division in the middle to make two 4x4 rooms.
I have drawn two figures, I'm not too good with words.
Figure "A" would be less...
Since you got no reply and I'm learning about this stuff too, i'll post an answer.
Air stones work with air pumps. You connect them with 1/4" tubing and the air from the pump gets diffused in the water by the stone.
