I now know for when I upgrade so at least I am further ahead than I was! The light I have does have a decent spectrum slightly less "blurple" than your average Amazon light) so it does alright for 1 or 2 plants, but once I want to grow any more I will need to upgrade for sure. Knowledge is key in all aspects of growing haha.Probably 110w at the wall.
Marketing is the enemy of cheap LEDs.
But it will work.
The LED lights on the high end of the market surely are as advertised, I mainly am talking about your average beginner blurple off Amazon that tend to all advertise as 1000w but are definitely not and use it as a marketing tactic to sell more lights to new growers.
Can't raise, but yes I have added a dimmer and I'm pretty sure the plants will stop foxtailing... thanks!
It might be time to turn it up a bit. I'd reduce my humidity right now too, if you're not living in the Mojave
Then I'd get patient because you look like you have awhile to go 
Could be very nice when you get there 
could be... or maybe it's LEDs, could it be?
Chill bruh. Mars is decent at best.
Not bright enough or too close or vpd is outside of spec or environmental issues or bad gentics or soil , or everything, or nothing or spectrum gaps , ...
First company that came to mind, that was why I made sure to emphasize it was an example, I realize they are far from top-end but in all honesty I haven't looked at many lights at the top of the line mainly because they are so beyond my budget right now. Point was, if you buy a cheap light on Amazon, it may not be nearly as powerful as it says, buyer beware, your mileage may vary.
I got the seeds for these plants from a mother I grew outdoors and she didn't foxtail at all, either. Definitely something to do with the indoor setup I'm thinking... too bright/close light is my guess. Maybe I'm overfeeding them, too... I used much bigger pots outdoors.
