Yellowing leaves on tomato plants
« on: May 18, 2018, 14:35 »

My 7 inch high Crimson crush and Gardener's Delight plants grown from seed are ready to go out, but their leaves are yellowing from the tips inwards. A very pale yellow.

I had put put it down to unnaturally cold weather weeks back, but now I'm not so sure.

Any suggestions please, and would tomato feed be any help with young plants?

Are they still in smallish pots? The plants have probably used up all the feed that was in the compost - they only add enough for 4-6 weeks nowadays  ::) Try a half strength liquid feed or seaweed feed is very good for plants that need a pick-me-up.

As mum said a seaweed or liquid feed with a balanced npk 10-10-10 etc donít use tomato feed at the moment you could also add some Epsom salt which will help and water if you also mist the plants with a mix of seaweed and Epsom the leaves will take it up quicker

If itís the older leaves then itís most likely nitrogen deficiency, a feed wouldnít harm them

Another one to recommend a feed. For the plants that tend to stay in pots for a long time (ie Toms, Peppers) I tend to chuck a few manure pellets into the compost mix as the MPC runs out of fuel in a month or so.

I've planted out all my Crimson Crush and Mountain Magic tomato plants this morning.  It was that or pot them on again, because even with feeding, the pots were so full of roots I couldn't keep them watered enough. The next 10-12 days weather doesn't look too bad, so hopefully they will have established and acclimatised by then.

Fear not, crimson crush are determined beasts, Mine went outdoors over a week ago, and I still have a few in small pots, not knowing where to put them. They'll all yellow when short of nutrients, but my outed plants are now showing plush new green growth. Seaweed, a bit of Epsom salts, even some diluted comfrey tea, theyll like it all now as some are beginning to show some flowers.

Seems a consensus of opinion on this one. Sound advice which I'm acting on.

Thanks to all who replied.
