[Grapefruitroop]

Since a week this plants from a friend are turnin weird...
The fact that just some of the total are getting sick, and taking in account that hes feeding them all at the same way, makes me think for exclusion that they are affected by some bad fungus or pest...
anyway...any help will be greatly appreciated!

50% peat
20%coco
30% pumice
every 0.8 cft 1 cup of oystershell and gypsum 50/50
1/2 cup azomite
1/2cup ewc
1/2 seabird guano high n high P
1 teaspoon sul po mag

mainly fed with water and compost teas

Looks like russet or broad mites. You said only some were sick though?

Yep....it started with some, but now is expanding...
Also, the soil was recycled from the previous season (where there wasnt any problem)
Thanks so much for our input...
