Best for yellowing leaves

[Gilberd]

Hi

I seem to frequently get yellowing leaves on tomatoes and cucumbers etc when they are young and before being transplanted to their final position.

I have read that it could be magnesium deficiency. I just wondered how to rectify this. I have various feeds but wondered if I need a specific magnesium feed.

(I have grown from seed in compost)

epsom salts in the watering can I believe.

It could also be over watering, so easy to do with young seedlings. Doubt it would be magnesium deficiency if your using new compost.

This sounds like they need nitrogen? It leaches out of compost quite quickly. I usually get yellowing leaves at the bottom of the plant. Fed mine about 7 weeks after I potted on (sowed 2nd feb) Then fed again a month later. Im really happy with their condition at the moment,greener than usual

Magnesium deficiency usually shows as a yellowing in the leaf around the veins - Nitrogen deficiency poor growth with yellowing leaves.

Plants do lose lower leaves and they do go yellow unless it is on new growth and the compost is old then it maybe just the plants growing.

Nitrogen issues try a lawn fertiliser

Magnesium = epsom salts
