I have 3 bladed leafs growing out of my buds. Also, the buds are starting there 5th week of flower. They seem to be behind by a week or more. i'm using 2 Boss Led 3360 watt lights covering each 4'x8' flood table. I'm growing in coco. Reverse osmosis water with a PH of 5.3 to 5.8. CO2 burner set at 1600 ppm to go on 1 hour before lights out and off 3 hours after lights out. Daytime temps at 80 degrees and nighttime temps at 72 degrees. All general Hydroponics nutrients are being used. I added 15 more plants 2 weeks ago and they are starting to grow 3 bladed leafs as well. The strain is White Russian. Ive grown this strain before and they are diffidently slow to bud. I'm no expert here so please be kind. Any ideas? Pictures attached.
