also you dont neccessarily have to wait to change to your flower formula, i would just make sure the ppms are the same when u switch, the plant in theory should flower better if you change the nutes when u change the light cycle. But at the same time it takes time for the plant to switch to flowering however the flowering nutes should help it convert better i would think. If your plant is starting to flower and you have flowering nutes i would think of it as a catalyst. If you are starting to flower and still using veg nutes, i would think it would retard the plant.
JackdaWack Reviewed by JackdaWack on . are my ppms alright? My plants are now all about 2 feet tall, Still vegging them for 2 more weeks. I raised my ppm level from last week 1240, too 1440. Is that to much? I changed it last night. Rating: 5
