Tip - Detect PM Early With Blacklight

@Renfro
Hmm this is pretty random, but if you want a pound of primo only, in a 2*4 would you scrog 1 or 2 plants, or would you do a sog with plants like this? These are in 1 gallon pots I'd probably put 21-28 in thereScreenshot_20191126-230943.pngScreenshot_20191126-231642.png
TBH 28 I'd only have to hit 1 oz each.... still, what say you?

More Plants = Less Veg Time to achieve your goal.

Other than that, more plants is more to water and shit if that makes any difference.
 
FWIW, at the cost of added veg time, I think you get slightly better quality (and possibly bigger buds) from a larger more mature plant.

Just realized that many may not be aware of this little trick. Turn off your lights and use a black light to inspect for the beginnings of PM. Other molds like bud rot will also pop with that greenish / yellow glow.

That is an awesome tip. I just ordered a cheap $10 blue light flashlight on Amazon, but I don't know if I want to check out my girls mouth with it now, lol.
 
Tip to detect early signs of Mg deficiency.
I have used hps lighting to find early signs of Magnesium deficiency.
With hps lights on lay on the floor and look up at the leaves that are being lit by the light while avoiding looking directly into the light.
You can see the slightest change in some leaves at the earliest stage of yellowing between the veins.
Not sure if it would work with other lights.
I wouldn't trying it with LED, might fry your eyes IDK.
