Hi guys - I transplanted some celery from my mini system to my big system.
the mini system pump pressure had been changed by someone being 'helpful' who didnt realise it was reduced to a drip on purpose. They turned it up full blast and before I knew it i had a mushy mouldy grow bed.
Some of the plants got sick and developed a black spot all over them.
This mustve travlled from the celerly to the plants in my big system which ar all now getting covered in black spots.
Any idea how i can cure it? Or if it even needs to be cured?

my new groth on the celery gets browny black tips and stops growing. sounds like fungus doesn't it. what natural remedies for fungus? deiluted milk?

I only got that kinda reaction in my plants when they got TOOO wet - but if it is spreading then it has to be a fungus or something along those lines

Mine sounds a little different to yours Monya - these are little black spots about the size of a pin head that cover all parts of the plant.

eeeww. Hope you can get it sorted. Stufflike this certainly does complicate matters for us all

Could be scale.

Skim milk at 10% will help with mildew and fungus. Just foliar spray it.

Does it look anything like this. Just pruned off a couple of tomato branches that have it on them

Perhaps rust... Or maybe bacterial spot... I often just remove plants if something goes wrong, rather than trying to treat it..

Hmm, Monya.... my spots arent as prolfic as that photo and perhaps a little more raised off the leaf but if I remove the plants affected I'd have virtually no plants left so I'll try to imnrove the health of the system and see whsat happens. i'll try skim milk as well.

Another one to try is "dust of sulphur", good for mildrew and fungii related diseases.... organic and long lasting.

Sulpher is actually good for plants, excellent for preventing "rots" and is often used to dip cuttings into before transplanting... also applied to grafts and "wounds" on plants.

Haven't used it in an AP system... and would result in a slight increase in acidicity (often used in soils for that very reason), so monitor your system and buffer accordingly.

Photo would help, raised sounds like critters.
