Live Stoner Chat Struggling with my autos

[Zeke]

It was day 21 on Sept 2nd, I'm growing in Coco coir and perlite, I used 0 nutes for just about the first 2 weeks and they were growing wellish, now they haven't grown at all in the past week or week and a half, I've noticed some yellowing at the tips on all of the plants so I started to give them some nutrients but still no growth. If anyone could please share their wisdom it would be greatly appreciated!

Hey Zeke - Welcome to AFN



Coco is a soiless medium, rather similar to hydro - in respect of, it has no nutes unless you add them.
For the first few days, they'll be feeding off their cotelodeyons anyway, but following that, they'll need some nutrients.

Without knowing your setup and practices (ph management ...meter readings etc) it'll be diffifcult to diagnose any issues.

My best gues would be lack of feed and possible PH problems. It could also be environment, light, watering.

There's some good coco threads here, i'll fish you out a link and come back and edit it in!

All the best

Edit: Here's a link to the coco section (the stickies at the top have some good & varied information from coco users)

Thank you for responding so fast, I figured it would be a nutrient problem since I made the mistake of not using any for 2 weeks, but my pH is on par, around 5.8 -6.4 ish, humidity ranges from 49 to 57 temperature is always above 69 and always below 80

Super, i'd stick at 5.8 throughout the grow if you're new to coco. If not, then you may wanna try a PH swing during flowering to the higher end of the (nutrient uptake) range.
Temps sound good.

If you have an EC meter to measure your feed strength, i'd possibly consider going in at 1.1 EC with the base nutes and see how it responds.
I'd recommend watering to 10% runoff (unless you have an elaborate watering system)

Good luck!

Blues on it, coco is a feed all the time medium, devoid of any nutritional value on it's own. I'd get on it, and if under led, a little cal/mg

You guys are truly awesome thank you very much, and by 20% runoff you mean just water untill roughly 20% of what u water is draining, so should u hit each plant with a gallon? Seems like a little much but I have no fucken clue

I would water slowly, and wait until you have a the small drips coming out of the bottom, then add more until the bottom of the tray has about 1/2 a cm or so collected.

Then get rid of it if you can .. don't let the pot sit in it or it will wick back up.

If you can't get rid of it, put your pot on little feet and don't let the run off reach the pot. If you're in a dry area, this can help with humidity - it should evaporate by the time you next water.

edit: The point of all this is to rid the medium of any salt buildup caused by the medium (and nutes in it) drying .. the salt build up can cause PH problems.
I see it as re-freshing the medium.

Run off tests (PH) are next to useless in coco. With a good watering regime, you can be fairly confident that what you put in ... is what's in there. (if that makes sense lol)

 

[Arthur]

Depends on the size of your pot/bag. I'm running 3 together in coco, 3 gallon bags, and a gallon and a half once a day covers them all a little past 20%. But 1.5 is easier to mix up than 1.something.

 

[Zeke]

Okay, good to know, will my plants recover if I get them on track with nutrient levels and everything

 

[Arthur]

The extra is pushing out the salts left behind when the nutes are taken. Letting the sit in the runoff will draw that back into the medium, over a grow, the salt ppm will build and lock out new nutrients.
