How often do I water marijuana plants?
If you're growing marijuana in soil or another growing medium like coco coir, you will have to hand-water your plants.
But how often do you water?
Well, you will want to water your marijuana whenever the top of the soil or growing medium starts to feel dry. I like to water when the medium feel dry up to my first knuckle, or about an inch.
In the beginning, this probably means you will be watering your marijuana plants every couple of days. By the end, you may be watering them once a day as they will be drinking a lot towards the end of the marijuana flowering cycle.
Bigger pots = water less often
Smaller pots = water more often
You want to ensure that you provide enough water that you get about 20-30% extra run-off out the bottom of the container every time you water your plants.
The reason for this is that coco coir tends to form natural salts if it the fertilizers just sit in there and never get washed out. Making sure you keep adding water until you get run-off is also a great way to make sure that your plants are draining properly.
Plus, this will immediately alert you to any drainage problems, (marijuana likes well-draining soil) because you'll be able to notice if the water takes a long time to come out the bottom, or doesn't come ou at all.
It's generally a good idea to feed your marijuana plants with nutrients every other watering (at most) and provide plain, pH'ed water the rest of the time.
This will greatly help reduce the amount of salt buildup and prevent nutrition problems from occuring.
If your marijuana shows signs of drooping, chances are you are over or under-watering. In order to prevent over or under-watering, make sure you water thoroughly every time, and wait to water again until the top inch of soil feels dry.
Underwatered Marijuana Plants
Wilting is the first sign of underwaterd marijuana plants
Leaves are limp and lifeless, they may seem dry or even "crispy"
Will eventually lead to plant death if not corrected
Overwatered Marijuana Plants
Drooping / Curling is the first sign of overwaterd marijuana plants
Leaves are firm and curled down all the way from the stem to the leaf
Will eventually lead to leaf yellowing and other signs of nutrient problems if not corrected
If your plant is experiencing "the claw" and not just normal drooping (like the ends of leaves are just pointing down like talons, then you may actually have a nitrogen toxicity (too much nitrogen).
