I am a new cannabis grower. The last time I did grow was 30 years ago. I am a pretty experienced with hydroponics since I have been growing other things that way casually for about 20 years. The grow thus far has been very good. I have gone light on the nutrients to date and I think that is the source of the problem. The details of the grow are:
Method: hydro - autopot (first time using this particular method)
Nutrients: General Hydroponics Flora
Light: HLG 300L V2 RSpec
Tent: 3x3 Secret Jardin Dark Room
Ventilation: AC Infinity 4"
Planted on 7/8 (germinated in 2 days!)
Flowering for roughly 2 weeks. They are roughly 3 ft tall
Now for the pics:
It looks and sounds like a calcium deficiency. Those spots have just started showing up in the past couple of days. Any thoughts would be greatly appreciated including the best method of getting them healthy again.
