I would really appreciate it if someone could advise me what's wrong wit these cucumber plants. The leaves are going yellow and crispy, one at a time from the ground up. They are watered regularly and the grow bags have been split at the bottom so they're not waterlogged. They've had one feed of tomato feed so far.

Thanks

I'm no cucumber expert but it looks to me as if they need a feed of something or other. Yellowing between the veins of a leaf can indicate a chemical deficiency in the soil.

It might not be the best solution but, without looking it up or getting advice, I would be inclined to give them a slosh of tomato feed and see if this helps.

I think I might also give the leaves a spray of tepid water.

Don't rush at it.... see if someone comes along with a better idea first.

Mine looked exactly like that.

I fed them and a few days later gave them some epsom salts and cut the yellow leaves off, so far so good, no more new yellowing leaves have appeared.

Good advice there

Looks like Magnesium deficiency, give them a dose of epsom salts as Cazzy suggested.

Also water the area around the plants to keep the air moist - cukes do not like dry air. I nearly lost my plants in that way.

Thanks for the help everyone. I'll go give the advice a try.
