From a fellow grower: My Gelato plants are lanky with extremely sparse colas, actually there were no colas on the plants, just small clusters of buds several inches apart from the next cluster. I’m using a Spyder Farmer SP 2000 LED grow light with the rheostat cranked up to max once the buds started forming.
I use Fox Farms Happy Frog soil and Fox Farms Grow Big fertilizer. Water is pH checked between 6.3 to 6.8 each time I water the plants, EC measurement averages 2.5-2.8. I use a Blue Labs pH tester that I keep calibrated properly.
I use Fox Farms Tiger Bloom during flowering.
