Boron deficiency or not?

Been sick last 2 days, opend tent to find 4 or 5 mid lvl leafs looking like this…

Cali haze auto
Soil, ffof + mycos
Distilled phd water 6.4 - 6.6

This plant did have some bad claw, so i flushd with some hammer. I cant remember if i used just distilled water or nutes+ distilled with last water after flush.

To me that leaf is showing a calcium deficiency

Here is a great post by @Jbum showing pics and deficiency descriptions

Hope this helps


No link my friend :smiley:

I agree. Plant looks good: a little light green but starting flower so I’d let that ride. Cal mag though likely needed.
