Tomato problems

[Ian Foster]

Good afternoon,

I am growing tomatoes for the first time and they are being grown in a greenhouse.

They were looking extremely healthy, however, suddenly, that has changed.

Please see the pictures.

What's the issue and can anything be done about it ?

Thanks

Ian

Could they simply have run out of food? Are they in grobags?
"When tomato plants are nutrient-deficient, they display several symptoms, including leaf discoloration, stunted growth, and blossom end rot. Leaf discoloration, such as yellowing or purpling, can indicate deficiencies in nitrogen, phosphorus, or potassium. Stunted growth and poor flowering can also signal nutrient deficiencies." - Googled, photo from RHS

Another thing I have heard of online is it also could also be scorch, which is why folk peg green mesh over their green houses, but I'd always back Geoff for the correct root of the cause! No pun intended.

I agree with Geoff, looks like depleted nutrients. Give them a few doses of tomorite, a top dressing of worm castings if you cen get hold of some would be good too.

Also, you'll need to remove the lower leaves soon anyway to help air circulate and fruit to ripen.

Hi,

Thanks for the responses.

They are in grow bags but I haven't been doing extra feed - done that now !
