Boron deficiency?
The8thChevronanswered grow question 4 years ago
Sorry I didn't notice before. You are using micro, which makes boron deficiency almost impossible. You need calmag. Easy peasy. Go buy a calmag supplement for your hydroponic setup or look up how to use Epsom salts in the meantime if you have to wait for delivery.
The8thChevronanswered grow question 4 years ago
I have the same setup as you. I recommend copying my nutrients. You can still use the B-52 if you want.

Looks like nitrogen, but if you're not using a micronutrient mix in DWC, boron, iron, sulfur, etc are all very possible deficiencies.

Should I wait for deficiencies to introduce more nutrients? I haven't given these plants any of the A.N. veg nutrients that I have for them. We are at week four today. Maybe there are deficiencies that someone could point out to me from my photos?Week 4
