im using hydro setup, my plants are 6weeks into flower and only one of them is drooping it's leaves....please i really need to fix this problem, its my biggest plant , everything is wilting, including the buds.
These people arent really giving you any answers here. I have the same problem with my plants and i'm trying a nutrient mix higher in phosphate and magnesium as well as i'm increasing my sulfer content like 3% and it SHOULD fix the problem but i cant promise anything. As far as the light as long as you're on a 12 12 system or similar like 11 13 or somthing than you're golden and with a hydro system you have the water you have as long as its not at a lower level then when you were vedge than you should be fine. if you're using soil than only water when the surface gets kinda crusty cracking dry. Also refrain from spraying the leaves with unfiltered water.
If that doesnt work i would say drain the water from your hydro system and put in some filtered stuff cuz a lot of local tap water has nutrients in them that can be harmful to your plant.
