Have a autoflower 9 weeks from seed, the strain is either critical purple or tangerine dream (seeds were given). Coco coir, 1000watt led, house & garden cocos a&b, temps 72 - 77 humidity 37℅ - 53% watering til run off. Droopy leaves. I lowered the lights to maybe get better light penetration to the lower sites.
(Will post pics if needed)

Skip watering for at least one day. Stick you finger in it two inches down ... still wet? Skip another day.
Put your lights at least 24 inches from canopy or you will burn them.
Make sure you got air moving.
Put your hand at the canopy for 30 seconds ... does it hurt? Then you are burning the plant.
Foliar spray with kelp to concentrations on the label.

If you are in smartpots they'll dry faster. If you're in hard sided pots, they are almost certainly too wet.
For a five gallon pot you should water about a half gallon per day on average. And water with two gallons of ph'd but un-nuted water ONE day a week.

They should look better in about 5 days.

It is impossible to overwater in coco as long as you remove runoff from your drip trays.

ya this is not true at all
Coco can be over watered, its def harder than soil to overwater, but it happens.



Never let coco dry out completely
Use wet/dry cycles along with lift a pot method while they are small and roots are exploring
Always water coco with nutes, coco is inert, it will not hold nutrients like other mediums. You dont feed it, it will start feeding itself

Currently my girls are 24 days from seed, they are in 2g fabric pots and are being watered to runoff every 2 days( takes them this long to start feeling light again), within the next 2 weeks i expect they will begin consuming water/food atleast once a day, maybe twice, by mid to late flower they could be drinking 3-4 times a day depending on strain.


Go check out the hydroponics section, drain to waste...Tons of good info in that section about coco.

Ok bud, as long as you mix in some perlitr, your coco will never drown your plants.

When I first started I was over watering like a madman, 3 times a day constantly moist,, the only side effect of that was wasting water and nutrients.

Now I use Tropf Blumat drip emitters and they are constantly moist with no runoff.

Again you cant over water coco, thats why it works so well for newbies.

I'm still learning coco myself , having only grown 4 crops in it so far, but I have been learning from some of the best around here, guys with 20+ years in the game, they say otherwise. Coco can def be overwatered.

I'm too new to argue either way lol


@Renfro what say you?

You can definitely over water coco. It needs to dry out some but it's important that you don't let it dry as much as soil. If you keep the coco saturated then root rot is going to happen. Seen it happen. Damn near killed a few plants early this round because they were drinking much slower (strain) and I was watering them at the same frequency basically keeping them saturated. Really fucked them up, shoulda just tossed them. I have also seen it happen when a grower keeps watering at the same frequency after the plants slow down on drink around day 50 - 55 of 12/12.

But hey, what do I know.

I raised the light back up a little bit and went without water for a day and she had her leaves pointing up on her own. I know it isn't too hot and I have good air circulation. And the pots drain fine, perlite mixed in with the coco of course. I just didn't know why she was sagging so bad. This is my first auto but I have grown a few photos. So I'm not a complete newb. Thanks for the feed back.

Auto or not ... I don't think its the genetics.
You don't need perlite in coco.

Roots need a reason ... if you deliver water and nutes constantly the roots don't need to seek, or develop.
Don't let em dry ... but, its ok if they get a bit thirsty by skipping a watering once in a while, then when they do 'eat', they take it up with gusto, and put on two inches.

Sounds like it is more a plant/grower problem & not coco..

Yes you do need perlite but whatever man. This thread has potential to just turn into an argument.

Yea, they almost all do here.
People don't realize that there are many ways to achieve the same goal, they get invested in their methods.
It doesn't mean my way is better, or wrong or whatever - just different.
It's good to get different ideas.

But, often, the first ten or twelve posts are useful; after that its just a dog fight.

Cheers, and grow on.
