Black spot on the bottom of my tomatos

[KreegDaddy]

Hello everyone!

Has anyone ever seen this type of tomato problem? Im running an ebb and flow hydro system, do you think this means too much water?

Any help is appreciated!

That is blossom end rot (BER). There are lots of threads here about that, what causes it, etc.

Horrible, isn't it? So disappointing to pick up a pretty tomato and find that.

From what I understand, it's a calcium deficiency, in which case people suggest to add calcium nitrate "snacks". It can also be caused by inconsistent watering (which apparently makes it harder for the tomatoes to uptake minerals).

At least so I've read. I didn't fix my plant with BER, I yanked it out and composted it!

Thanks for the replys. Yes it is a horrible thing. Now that I know what it is I can try to address it.
My plants are watered every 4 hours on a timed cycle, so the watering is very consistant. Ill look into some organic calcium nitrate.

THANKS AGAIN!!!

I know some of us have had plants that start out with BER on the first several tomatoes and then seemed to grow out of it. My Juanne Flammes and Green Zebras were terrible for that last year.

So a little touch of calcium probably wouldn't hurt, (if you haven't done that already) and it sounds like you have the water supply thing under control. Now just give them a little time to work it all out!

You may be watering too much.

I agree it may be too much. Watering several times a day is great when you want seed to germinate, but for established plants, I water deeply three times a week, to force the roots to go deeper and look for moisture.

it might be watering issues but also make sure your supplying calcium. if not look into some cal-mag
