Hello out there
I seem to have run into a issue i can't seem to solve.
I have 2 plants growing in
Our greenhouse.
Plants are 4 feet tall
Soil has been mixed with perlite ,stag manure and dolmite lime.
My issue is most of bottom leaves are dying and bottom half of plant is flowering.
some leaves look bleached.
Any help would be great
I do have spidermites as these plants are outdoor i spray weekly.
