Dwc sweet spot
GrowingGrannieanswered grow question 2y ago
The sweet spot is when both your EC and pH stay the same... VERY hard to achieve! There is a good chart to follow to figure out what's happening with those fluctuations and what to do about them.... look up EC and PH Fluctuations in Hydroponics - it's on a site called Percy's Grow Room... there are TWO charts - one for when your plant is drinking water and one for when your plant is NOT drinking/taking up water.... (I'd give you the link but GD has gotten a bit touchy about that and generally it results in being banned from commenting/texting... stupid)
Good luck!

LED Kelvin Temp 3000k-6500kIs there a massive difference in colour temperature/kelvin of LED's if the lumens, PAR, watts, intensity and every other aspect you can think of is the same but its temp/kelvin is lower? I use a 6500k LEDs, may mix in or switch to 3000K for better flowers if its proven to work.

Popcorn budsThis is my OG Kush outdoor grow. It's kind of a side project. Fed regularly with fox farms liquid nutes. The summer was pretty warm and humid. Will these fatten up or am I stuck with popcorn buds?

Possible runt?How old do ya'll think this plant is? Reason I ask is because it's an autoflower and it already has pistils growing. I think it may be yet another runt. I'm starting to get really pissed off.. I haven't done anything to stress it.
