hey my buddy has 3 plants and they all started to grow great but by the end of week three they all started getting droopy but the leave sets are a nice dark green but the tips are starting to curl and the first leaves that sprouted are now yellow and sagging, he waters once a day 30 ml, 18/6 light schedule, gives nutrients once a week 28-8-16, temps 75-82 degrees. why did it just start happening now?
Watering daily sounds like too much water.
If they need to be watered so often perhaps they are very root bound and need bigger pots.
If you are not watching PH in and PH out they are prolly locked out or soon will be. General Hydroponics has a drops kit and milwaukee has a yellow PH pen for like 20.
ok he moved them to bigger pots he said, they were in peat pots and he checked the ph and it was neutral and he started misting the leaves once a day, how much should he water a 3 week old plant?
Best way is to check the weight of the pots. If they feel heavy and water-logged, don't need to water. If they feel light (like a pot with only soil and no water would feel), then they should be watered.Quote:

Depending on lighting, humidity, temperatures, soil type and composition, he might need to water every 3-4 days, maybe every 5-7 days. Watering everyday is not recommended. Cannabis likes wet/dry cycles.
