RE: Hydroponic greenhouse - some problems
I have had similar issues before with growing tomatoes. I can suggest watering every other day than daily. For the dark spots on the bottom, read then from Bonnie Plants. It states that the soil may be calcium deficient: https://bonnieplants.com/library/conquer-blossom-end-rot/
Thanks!
I'm growing hydroponically in expanded clay pebbles, so there's very little water retention in them; I did set my system up so there's 1-2 inches of water at the bottom of the buckets at all times but still I would not be able to get away with watering every other day.
I have looked at the calcium or nutrient deficiency but my plants seem pretty healthy; if the recent watering schedule changes won't do anything I will have to find a way to measure calcium levels reliably and see how I can address that.
Ah gotcha, my apology in missing the hydroponic method. I hope you are able to figure this out.
