The immune system of Cannabis

[ISM2]

I was listening to an interview on CannaInsider with expert grower Nick Hice of Denver Relief. He stated, ""Cannabis is a seasonal plant...Once the plant gets about a month into flower the immune system completely shuts down."

Is there any science behind his statement?

Plants have an Innate immune system (so say the plants gets ill, it will not spend the time or effort to repair the infected part(where as we need to keep our parts) but would sooner just discard it (Hypersensitive response), hence they don't generate antibodies like we do), so as to what shuts down I don't know but if it did I'd wonder how do they reveg healthy? surely it would just die....

One way to find out would be to see if a plant is still producing Methyl jasmonate after the time given by him as that is the plants main compound used for defense against insects and pathogens, or maybe the fact that a plant near the end of it's flowering cycle can still produce the late "nanners" tells us it is still getting signals and responding if it had shut down I'd of thought this was not possible.

I don't know Nick Hice, but that statement is simply untrue.

If anything, the plant's natural defenses ramp up during flowering.

What do you think all those glandular trichomes producing anti-fungal, anti-bacterial, and semio-chemical compounds are present in such quantities for?

Is it just a coincidence that these compounds are all produced in the highest concentration surrounding where the next generation is to be nurtured and matured ie- the bract/calyxs? I think not.

Just like a woman's womb is full of defenses to protect developing future generations, such is true for cannabis.

I'm with chimera,
Dude has some plant nutrition issues if his plants immune system is "shutting down". Sounds like he's a real plant expert.
Maybe want to look at the amount of phosphorous and calcium being used.....
