Hydroponic virgin, yellowing and curling. Ph balanced, all plants aresame age

Thanks guys for so many great messages! I think I've got it nipped. I did not have a gap between my basket and the surface. I happened to buy myself a nice little Christmas present and I'm learning the light as well. Okay I might be a little bit strong now that I've turned it down all is good on the homefront! And again, thank you friends! in a matter of hours The girls were perking up and seemed to be almost catching up in front of my eyes

I would check the ph and solution temps. Make sure your air stones are supplying enough oxygen. Lastly make sure buckets solution isn't touching your net pots. Let the roots grow down into the solution.

Actually feeding the grow formula (picked the wrong one). I do not have a gap though will try that. I did soak the rock wool and drop the pH.

According to your diary your feeding bloom nutes. I would still be using grow nutes at this stage. Also you have no mention of ph which should be about 5.8. If you didn't pre soak your hydroton in ph 5.5 1st that could cause a problem. Make sure you have a gap between the basket and the water.
