Is this the signs of a nitrogen deficiency or am I not feeding enough Canna A&B? I'm coming up to end of week 4 of flowering.

Lime Green Growth Tipes
The growth tips on my plants are super lime green compared to the rest of the leaves. Is this a problem? I'm growing in FFOF and I've given very little CalMag and P-T-K so far.

Continuing calmag deficiency
What I think is a calmag deficiency started about 10 days ago. At first I thought it was too low PH (6.0 - 6.1), so I corrected that, but no luck. Then I started adding biobizz calmag, still no luck. It seems that the deficiencies are picking up speed again. Any ideas appreciated

Purp stalks, weak leaves.
Hey guys i noticed that my stalks were all turning purple and my leaves are curling. Is this a nute lock out ? Or is it light burn ? I started them under a pretty powerful Led but still getting new growth through the last 2 days. They look thirsty but medium is still soaked.

Nitrogen Defficiency?
I’m growing with super soil and amendments for this grow. Looking for the Autumn Color Effect. I understand that you need a nitrogen deficiency to get this, and if timed right it shouldn’t affect my yield. I’m on the 5th week and one of my phenos is pretty yellow. Is this okay?
