Plants yellowing in Coco Coir

ANC · May 3, 2017

comparing coco grow to soil, I notice the soil plants tend to be darker, pointing to more nitrogen... I would start looking there. Aquarium water, especially from the filter is a good source, already broken down by nitrifying bacteria from ammonia.

No one knows what the problem is. Everyone is giving their best guess.

You need more mg. That's your problem.

Maybe you should read the previous posts more carefully. :dunce:

I've been feeding them 3 tablespoons of fox farm big bloom per gallon of water since flower ever other watering using regular water.

You are not feeding them base nutrients? No part and b? Every plant needs these, you are only giving them the extras to make your buds bigger, plants need their food!

I did.

The best answer I saw was to add Cal mag. That will certainly fix his problem but he has posted a picture of the plant with the leaf yellow and brown dead spots on it. That is what happens when the plant is out of mg. If it was low on N the leaf would go a healthy yellow and no dead spots in the middle...

The reasons were stated correctly. Coco has a high cec not a low cec, so you need to charge the coco with some Cal mag before use.

You never use just water in coco - everyday is feeding time.

Make sure it's not a pest problem i.e. fungus gnats and root aphids. When I ran coco I always thought I had some kind of cal/mag issue, turns out I had root aphids. Had to shut down the rooms for a bit after root aphids.

Cal mag won't compensate for a complete lack of NPK.
Derp. :dunce:

Pretend your coco is 100% hydro---cause it is. Flush the shit out and make that root zone 6.0ph and feed a cal mag up until week four and switch to a mag/sulpher the last half. Speaking from experience with coco. the benefit to coco is quick fixes. If your plant takes more than two days to pull out of stress, then I would assume the root of the problem is more in the plants environment. BUT PH is certainly the most important in FLOWER. COCo is the bees knees. ran every system under the sun hydro and never going back to anything else

Can i randomly add that i found it hard to overwater seedlings in coco even flooding them once a day and that even seedlings need feeding. Every water should be ferts too.

Just wanted to pop that in :-)

If I said it, quote it. I never said it. So why are you saying I said something I never?

It is very difficult to overwater in coco but it has happened to me when the coco is very very fine. Good quality coco you won't beable to overwater. However I have had coco that was almost like powder... That stopped a pot from draining! Just make sure your coco is high quality then you are good.

Would you like me to requote it and bold the part where you said cal mag was the solution???
Nobody is this dumb. Are you a troll?

Chill guys, no need to fall out...

I changed to canna a few weeks ago, watering seedlings everyday and they loved it. I was mucho supprised after reading all the threads where people had overwatered seedlings. Love this coco now and dropped soil for good as am a total convert. It would appear that seedlings germinate best at 0.7ec and above but ive just had the police and landlord in my face about growing weed so i had to start everything again after a quick clean out.

Possibly im coco for life an i am freaking amazed, when i pulled the plants out i literally couldnt believe how stunning the roots were. Churchaze madfe a lot of sense with that 1.0ec to 1.4ec for starts hmmmmmmm.... :-)

What did you use before? Just curious. I'm using the bio bizz stuff and it's pretty fine.
