While these sorts of things are true, they are a small proportion of the total pie. You will grow weed just fine under a blurple light. The largest factor is providing enough light more so than fretting over spectrum (within scope of normal grow lights that already focus on PAR or red/blue wavelengths). You will not have problems. I grown clones from my first seeds that were intially under less optimal spectrums and then under better diy lights i made... the biggest difference i saw was a saving in watts per sq ft covered. So many other variables at play, and i couldn't see much of a difference in outcome with the clones. Red can make it grow taller. Blue can make it branch out more, but both of those things are relative to any individual plant's genetics which make up 95% of the outcome in this regard. E,g, you can take a lanky plant that doesn't naturally branch out a ton and only give it blue wavelengths.... it won't be much different even if a statistically significant difference does occur... these are small differences that take large samples to discern. worry more about providing as much as the plants can handle per 24 hours. That'll improve results more than fretting about wavelengths. When you buy a new light, that's when you want to get all your ducks in a row on specifications. This is what you got now, and it will work fine as long as it has enough power per sq ft. (power in this context is umol/s of photons produced, not watts) new research shows real benefits from wider than PAR range of wavelengths. Even so, these differences are small even if measurable beyond the static of all the other variables at play.
