Pepper plant with blisters on underside of leaf

AJ87 says:


I have noticed that my pepper plants (and now seems to be tomato plants) have blister like lumps and the leaves curl upwards.

They are in a conservatory.

Any ideas as so what it is and how to deal with it would be greatly appreciated.

    Looking at the small pots I think it's the plants reacting to water stress so would re-pot them into larger pots.  Another possibility is spider mite.  You will need to use a magnifying glass to see if you have those on the underside of the leaves as they are too small to see with the naked eye.

    A trowel in the hand is worth a thousand lost under a bush.
