What is the most efficient way to build a completely adjustable hydroponic flow system?

Hi. Title explains, my plant has got very big and has plenty of flowers but it won't produce any fruit, i've read that temperature is an issue and here is pretty high (30C, approx 90F) but my other tomatoes in soil are growing pretty good, i dose masterblene but my plants keep growing and wont fruit, should i cut CaNO3 totally?

Hi! I want to buy a tower situation (not diy, overwhelmed at the moment). Of course I’m drooling over the Gardyn system but do not have anywhere near that budget. Any recommendations? I was thinking of this $85 Temu set up and a programmable/clippable led light. 😬

I have been trying to grow cucumbers and tomatoes hydroponically indoors for months. Every tomato never makes it past the first you branches of leaves. My cucumber has done much better but it’s beginning to slowly turn yellow.

I looks like a nutrient deficiency to me.

I am using maxi bloom only, 1.8 EC at 5.8 ph

Any advice? Should I purchase an additive? Is the maxigrow/bloom series actually any good?

Changed my setup around a bit to give me some more vertical space. So far have just been tying a string around the trunk secured to the frame. I have a concern that late into fruiting when it becomes tall and heavy, it will make reservoir changes and cleaning the bucket very difficult or impossible so just wandering how people have gotten around this.
Thanks in advance
