My friend asked me this earlier today and im not to sure so i thought id ask the city. "i had my plants growing 18/6 and then i put them 12/12 the next day i went back 18/6 (his an impatient prick that changes his mind all the time.) Then i put them onto 12/12 a few days later.. they have been 12/12 for 3 days. I want to put them back to 18/6 cos i realised they are still to small. Will i stress them out to much? theres no buds yet?" What ya guys reckon? i think it will be fine to go back to 18/6?
I mean I suppose if it is sensitve it could stress them to herm. But if you have gone back and forth and nothing so far it will probably OK.
since its only been 3 days and the buds havent started yet i dont think it will hurt to much but i would stop going back and forth. i have sexed early by forcing flower and seeing if male female then go back to veg with little shock so you should be fine
