This Lemon Haze is growing extremely well, had no problems at all with PH swings or even nutrient burn. It's definitely a heavy feeder. As soon as the temperatures dropped to about 24C/75F it started showing beautiful shades of purple, something that I personally have never seen a Lemon Haze do. I have to mention I am using LED's and leaf surface temperature with these lights is slightly colder, different than HPS lamps, that's why you can afford to run your grow room at higher temperatures with LED's, which in some cases can be even more beneficial.
By now it also started yellowing it's fan leaves, without any specific nutrient manipulation, no need to cut nitrogen. This plant is just working as a well tuned machine, beautifuly self-regulates its PH in the rootzone and knows exactly what she needs and when, making the grower's life much easier and giving me more time to just sit there in awe hypnotically admiring it.
Have a look at how great it looks:
