Nitrogen starts yellowing at the bottom, if you have abnormal growth or yellowing on new growth it would be calmag.

I can't see it clear on the photo. Make sure the PH pen is calibrated, also take a look at the new growth after you added the Calmag

Most likely nitrogen deficiency. I know nothing about hydro though, feed needs increasing if it's draining the leaves. It's basically eating itself to survive

Younger leafs are discolering. What to do?This week my WW started getting pale? I tried to look on examples on the net of discoloring leafs. Is this a Zinc defecienty? She seems to be struggeling a bit because of the colder nights. Could this also be due to that? Looking forwards to your answer, dear question replier!

Soft hanging yellow leaves, some with brown spots in the middle. Deficiency, Nutrient Burn or what could cause this ?Hey guys, I got a problem with two of my 4 plants. They started to develop yellow droopy and soft leaves that start to fall off on their own. I’m not sure if it’s a nutrient deficiency or blockout from ph or something else. I watered them only with water ph 6.5.
