Hi guys
I have a little problem with my Northern Light plant. Over a week now on middle and top leafs i noticed several rust spots. They appear in the middle hight of plant and the higher i look the more of them. First i thought its cal but leafs are not yellow at all and the problem starts on all leaf not just on the edges.
I have 3 different plants in my room (WW, Skunk#1, ICE) in 3rd week of flowering and water them same water (boiled, standed, pH usually 5,8) under 400W HPS dual spectrum in soil and they are all fine. I add minimum recommended dose of BioBloom, TopMaxx and PK13/14 every 2 waterings.
Last two waterings didn`t add any nutrients, just water and last watering increased pH to 6,4 in case its Ca blocked coz of low pH.
Any idea what that could be?
Thanks in advance
