They’re small and idk 3 weeks old, no signs of deficiency aside from blossom end rot.

Was set up with Manutec 1L Hydroponic NK Plus For Fruit And Veg. Water is about half depleted, has been hot so possibly nutrients are concentrated?

pH had risen to about 7 from 6.5. I readjusted it to about 6.5. In dirt this range would be fine for calcium transport.

Oh hydroponic wisdom people, enlighten me. Should I just remix new solution? Add a supplement? Is pH for transport different in hydro?

    Seems like you’ve got fungal infections (mildew and maybe butrytis).

    I’ve heard that stuff like melons, cucumbers and so on aren’t very attractive to pollinators, so they can really benefit from hand pollination. I think virginity will be its cause if death :(

    The pH range is fine I guess. It being a bit off won’t harm the plant catastrophically, it will only make absorption of some nutrients a bit harder.

    I wish I could say something more uplifting, but I think it’s over. The fungal infection is too advanced, and the blossoms are dead, you can only take that as a lesson and try it again next year.

      I’ve been able to keep courgette alive quite far into a powdery mildew infection. I think if they start manually pollinating and then remove the flowers after fertilization, they’ll be able to get some fruit off this.

    And powdery mildew. But they always get powdery mildew.

    Solution to blossom end rot is to hand pollinate to ensure fruit set, wait till pollination takes, and then remove the blossoms by hand. You leave the blossoms on, and you increase the chances of end rot substantially. Not sure it being hydroponics or nah is relevant.

    Additionally, these plants are monoecious, so you have to learn to ID the male and female flowers. The males are on long stem and have the anthers. Rip the petals off and it makes for a decent pollination wand.
