I am looking at doing auto plants with the 4-4-4 spikes and the 2-7-4 spikes in coco coir in 3 gallon fabric pots. I am thinking about breaking 1 of the 4-4-4 spikes in half and putting it into the pot when I put the coco coir in then break 1 of the 2-7-4 spikes in half and putting it in at the start of flower. Would that work similar to biotabs with it?

Give it a try
Start at a low ppm nd slowly increases till you see slight tip burn then go back to the lowest dose again should be fine
Best way to learn is to just do it
Let us know the results if you do go ahead with this
Good luck all the best

It's my understanding that these "Jobes Fertilizer Spikes" are slow release and might not release fast enough for coco. I could be wrong about that though. Doesn't hurt to try but keep your normal plant food on hand if deficiencies show up.

I'm pretty sure they won't over-feed. I'm not confident they will feed enough. At least this is what I've heard before ... Someone here may have tried them already and might have better input. Those spikes have been around for years.

Yep did a whole grow using the 4-4-4 and Tomato spikes in bloom, it went so smooth my only complaint was how boring it was (you'll have to add calmag regularly though) I'll find the link and post it up when I get a moment

Edit: I wasn't in Coco, don't think I would try it in Coco, but I'll put the link up anyway

Thanks. I also have dr earth dry fertilizer in 4-6-3 and 3-9-4. I may do a mix of 70% dry 4-6-3 and 30% 3-9-4 fertilizer when I put the plants in the pot then put in a 2-7-4 spike when it starts flowering and also top dress with some dry 50 50 mix of the 4-6-3 and 3-9-4 dry fertilizer at like a half strength of it.

Thanks. You did the 4-4-4 spikes and the 2-7-4 spikes? I do plan to put calmag with the silicon in the reservoir that feeds it with the autopots. Did you use coco for it? I have been trying to find out more information on this for a while. Would you mind telling me how big your pots were and how many spikes you used and when?

I don't get involved with Coco it's just not my thing but a lot of people like it so I don't really want to comment on it further, anyway here's the link, if you try it maybe start a journal I'd like to follow along, good luck!

Thanks. I will read your thread. I wonder if a mixture of the spikes and dry fertilizer amendments in top dressings would work better with the coco.

Not sure if you got a clear answer on this but this year I got some Jobes house plant food spikes NPK 13-4-5. My seedling popped up on Mar 23. I waited until the seedling was 3-4 weeks old to add 1 spike not far from from it and 2 weeks later (as I'm using a 5 gallon bucket so the diameter is 12" or bigger) I added the other 5 spikes around the drip line (as the instructed number for my bucket size called for 6 spikes). Today is May 28th and so far my plant has been healthy, green and growing nicely. If you didn't know, these spikes last for 60 days so before June 21st, they should have expended all their nutrients into the soil. Then, as long as my leaves aren't yellowing up or anything like that I'll go to the water solable fertilizer for flowering. I do have a cpl leaves that have one little tip on the blade or one part of the edge of the leaf that turned brown which I know is a sign of over fertilized but this has been minimal and is no threat and as I said, literally 3 leaves had one blade had this happen (which are lower leaves) the rest are fine. So to answer your question, yes I believe the Jobes spikes work just fine for veg!
