My critical purple and hindu kush have began to flower an really gained some size in just about a week an a half they were only half the size! Sent from my SM-G965U using Grasscity Forum mobile app
Looking good. Careful with the yellow leaf tips. Those, plus dark green leaves means you could be on the verge of over-feeding. Looks like you're in hydro. My DWC autos would want about 300 ppm at this stage (EC=0.6). Autos might need less food, and there's an easy way to know in hydro when plants get big enough to speak for themselves. If ppm rises from day to day, the plants are drinking water and leaving fertilizer behind, so decrease ppm. If ppm falls, the plants are eating fertilizer and leaving water behind, so increase ppm. Eventually you'll find the correct ppm level so that it stays relatively constant.
I haven't stopped I was going to continue with both until they're really starting to flower an the buds start to grow then slowly switch to bloom nutes Sent from my SM-G965U using Grasscity Forum mobile app
I made the mistake of feeding bloom a little to early imo. I got scared of it getting too tall so at 32" I fed bloom. It hasn't grown 1" taller or 1 new leaf since
No biggie. They go through spurts just like photos. You could have kept feeding "grow" or veg nutes one or 2 more times after seeing preflower, but it's also ok to start bloom soon as you see em. Lights can play a part in the strech, but the genetics and phenos within it is gonna do what they do.
