X4 dark devil auto

What a change in pace this week! These girls are fast. Between day 19 and 20, the first pistils have come through at the internodes. Day 20 and 21. All 4 have now started their pre flower stretch. I will be adding big bud into the nutes mix from now until flush. Added a 12 inch oscillating fan to the mix. Girls have reacted really well to the added turbidity. The Humidifier has been removed. No need for it any more, plants are transpiring enough to generate their own humidity. And the eagle eyed of you will notice the addition of cfl's. I've read that addition of cfl's can increase trichrome production (nothing ventured nothing gained, it will add another 105w of lighting slap bang in the middle of all 4). I noticed slight tip burn on some new growth on the 19th. I added 2 litres of tap water to each of the pots to dilute and rinse any salts out.
