Amnesia XXL Dinafem - First Grow

Amnesia XXL: Original Amnesia x Original Amnesia Auto 5 Gallon Pot, about 65% Canna Coco coir medium (rinsed, amended and rinsed before planting seed), approximately 20% Miracle Grow perlite and 15% Wiggle Worm Castings, amended with Gaia Green 4-4-4 and 2-8-4 slow release nutrients. I will be cutting the Gaia Green 4-4-4 nutrients down to 3 tbsp per gallon/ 9 tsp per gallon for my next grow amendment and keep 2-8-4 application the same. I use only vinegar to PH down. My tap water is slightly hard (PH 7.4-7.8) and loaded with calcium carbonate. Plants have had small fan(s) blowing on them since a few days old. It seems important to build strength in stalk. Tent: Vivosun 36x20x62" Light: Phlizon CREE COB 1000w LED / 245 true watts (x2 Cobs) Fan & Filter: Vivosun 4 Inch 190 CFM Inline Duct Fan with 4" Carbon Filter Gro Pro 724815 Premium Nursery Pot Squat, 5 Gallon This Amnesia XXL grow, my first grow, has been under veg and bloom lighting 24/7, since the seed was dropped into a cup of water. My goal is to keep her short, and to hopefully induce larger cola growth on the tops, rather than lots of popcorn buds below.
