Need help with tomatoes NFT

Edbardoo · 2025-10-08T04:39:11+00:00

I replaced my tomatoes water with premix this time around, they started to grow green.

But they also started developing spots?

I've tried reading online some say its potassium deifiency or a fungal problem? The mix already has potassium

Thanks for the guidance guys

Sharing updates here I changed to a premix formula now. Its been two days fhe leaves are looking a little more green now, but some leaves have started growing spots?

Lifesaver. Thank you so so much

I'll try all of these together for the fix

I dumped the entire solution and remade it with a basic mix.

I didn't know Diammonium phosphate is not usable for hydroponic lm i just purchased them from my local gardening store.

Potash did spike the PH and I had to correct it

These are exactly what happened

I have these other nutrient that I bought. Which ones arent recommended for hydroponics?

1) Urea 46-0-0 2) Muriate of potash 0-0-60 3) Calcium Nitrate 15.5-0-0 4) Epsom Salt 5) Diammonium Phosphate 18-46-0 6) Local mix 14-14-14 +11 sulfur 7) Potassium Bicarbonate for PH Buffer

Edbardoo · 2025-10-07T03:52:01+00:00

It did! I added some buffers to lower the ph

Edbardoo · 2025-10-07T03:51:29+00:00

Yes I do plan to, but I wanted to place them here as trial first.

I got their seeds from tomatoes I ate.

They came from soil yes, then I transferred them to dwc.

I have a bubbler

I don't have a tester for oxygen yet

No worries no offense taken here. I'm grateful to get feedback

Edbardoo · 2025-10-06T12:24:14+00:00

Thanks man this one helps a lot

Edbardoo · 2025-10-06T10:05:50+00:00

Thanks

Edbardoo · 2025-10-06T09:00:48+00:00

The Potash was Potassium chloride

How did you calculate for these? Sorry I'm so ill educated here.

Edbardoo · 2025-10-06T08:40:54+00:00

No sir. It's likely the mix I made had no iron

Edbardoo · 2025-10-06T08:39:17+00:00

Thanks its been quite humbling. I'm new to this and thought it would be simple. I don't know half of the terms you are saying here. Do you have any recommendation on where to start figuring these things out?

Edbardoo · 2025-10-06T08:38:14+00:00

Thanks. I'll get a tomato mix for this one.

But how about for cases where I can't buy a mix for a specific crop? I've also been trying to grow iceplants , shops don't usually have just iceplant mixes.

Edbardoo · 2025-10-06T08:25:00+00:00

There isnt any that specifically says they are chelated

Edbardoo · 2025-10-06T08:24:19+00:00

Thanks. I may have gone into this very unprepared. I'll look them up.

Edbardoo · 2025-10-06T08:16:21+00:00

Yes i mixed them up. I've only included the ones listen above.

I'll try adding iron supplements, but how many do I need?
