Hi everyone, im having an issue with my leaves turning a rust-like brown almost over night! im afraid it might be fungus or something.
if it is has anyone seen this type? and know a cure for it? below are pictures to help.
The rust starts from the middle of the leaf and works it way outward
Some parts curl up or down where affected
The affected parts are soft and NOT crispy
Half of the plants are seeing this now
My Grow
where: 14X14 green house
Strain: White shark
Medium: coco peat bricks. from vietnam. very sandy and high EC. Washed myself and added nothing to combat low cal-mag problem
Container: 7 gallon felt bag
Light source: Yellow ball in the sky
My Climate
Rh% 60-70
Temp avg: 35-40 C at afternoon, 26-35 C at evening, 20-25 C at morning
Ventilation: two sliding doors open at both ends with fans on the other end for exhaust + two rotating fans
My Nutes
Botanicare product line for coco + following their calculated guide and going half strength
I understand fungus loves high Rh% and now i have this problem, Probably due to that fact alone. however, due to complications of lowing the Rh in a greenhouse i cannot do so readily; does anyone know of other ways to combat this?
