Hello,

Planted some "Tomato Tumbler" plug plants last week each one in a large
pot using stuff from a grow bag and some water crystals.

Noticed today that the young plants are going a bit yellow.

Is this too much sun, as they are out all day or nothing to cause concern ?

Thanks.

Mike

Yellowing is not good.

AFAIK you can't give tomatoes too much sun (certainly not in the UK).

Could be too much water - ISTR that cold/draughts can turn the plant
purplish but not yellow.

Is there reasonable drainage?

Once established and growing strongly it is hard to overwater tomatoes (but
it can be done if you try really hard), but when they are little they need
more care.

All a uniform yellow? Or perhaps some older leaves are yellowing between
the veins? that is common an is probably magnesium deficiency. Spray
with a very dilute solution of Epsom Salts.

Mine did the same last year.
It was magnesium deficiency.
After using some tomato feed they picked up quickly.

Check the bottle carefully.
We found that some of the discount shed own-brand stuff didn't contain
magnesium, whereas the branded stuff like Tomorite did.
After careful ingredient label checking we started useing Homebase and it
seemed fine.

Bearing in mind that this is a plug plant newly potted up (one week ISTR) it
hasn't really had time to develope magnesium deficiency, surely?

More likely a more serious problem in the potting up.

Still a little early for tomatoes outdoors (depending on where you are)
although I have chucked some Garden Pearl out to sink or swim.

It can happen very early. I had it on seedlings indoors sown in
multipurpose compost. Probably at a similar age to the OP's plants. If
the OP confirms that the detailed symptoms are as I suggested, what else
could it be exactly?

My guess is the compost is too wet, because of the water cystals which have
been added.
