Hello, I’m new to gardening and started a veggie patch. All was going great, but then I had to go away for around a month. Before I left I noticed some yellowing on older leaves - looked to me like N deficiency as they were consistently pale. Before I left I fertilised them with a mix containing magnesium, calcium, potassium phosphate, nitrogen phosphate (I can’t remember what the ratios etc were…). When I got back, my veggies (particularly tomatoes) are all nearly dead! New growth also now looking dodgy (the pics where I’m holding the leaves are of young leaves).

It has been raining heavily here pretty much every day for weeks, so everything is very very wet and humid.

Looking up nutrient deficiencies online, to me it kinda looks like a mix of most of them! But I’m a total novice with it all. If anyone could help me diagnose the issue it’d be much appreciated!

Thanks in advance.

Whoops I wrote the wrong nutrients sorry, meant to edit before posting but then forgot. The fertiliser mix contained:

Monopotassium phosphate
Potassium nitrate
Magnesium
Calcium nitrate

Greetings, welcome to the Forums.

Many of your Tomato (Solanum lycopersicum) leaves look like they have Septoria Leaf Spot (Septoria lycopersici), a fungal disease. Treatment involves removal of infected leaves and debris. There are also fungicide options that you might consider.

The good news is your Squash (Cucurbita spp) look fairly healthy. The white spotting on the leaves is a normal leaf vein pattern.

I don't see any strong evidence of nutrient deficiency. Of course,do incorporate compost into your beds at the beginning of the season, and also fertilize your crops as recommended.

Ah ok, yes that makes a lot of sense! I couldn’t figure it out as the broccoli looks incredibly healthy, so thought it was strange that the tomato would seem so incredibly malnourished while the broccoli thrived. I suppose all the humidity promoted the fungal growth.

Thanks so much for your help!! Have a great weekend :)
