My plants are dying, please help.

I'm not a fan of Miracle Gro, I have never used it. But to suggest that it is full of chemicals that will be absorbed by the body and cause harm when smoked is utter crap. You are just repeating shit you have read on the internet as if it were fact.

Miracle Gro is just the same as any other mass produced salt based fertiliser. As you know so much, can you please explain what is wrong with this...

My opinion doesn't mean much around here, but I agree with you. My parents have been growing with MG for probably 60 years. There is a reason for that. Of course it's not pot, but still. Actually, I put 2 pot plants on their back porch last summer to see how they did compared to 2 of the same on my porch. It was fun having my 79 and 80 year old parents growing cannabis lol. One turned out ok, the other was a bit slower and I forgot about it. Probably still there.

I'd love to see pics of one of your coco grows :)
Wow! Quite the competitive nature instead of helping.
I'd rather you sit there and fester. ;)
Ignored. Have a great life.

@MisterBlack - if you insist on pics yourself personally, I'd be glad to share via pm. I won't post pics publicly. FWIW judging by your previous successful grows, like your outdoor season, I'm of the opinion you already have a good idea. And that you're already moving things in the right direction.
All my advice has been toward potting mixes and soil in containers. Not coco coir.

Moving on from this thread, I had already said what I needed to say.
Again, good luck.

I think I will just water it for a bit and see what I see. If something looks like an improvement, I can always add some fert later. I am going to start with new soil on the rest when I get it but for now I will see what it does.
Ok I'll try one more time to save you. You have a burnt and starved plant you have now moved to an inert medium. Think plastic, if you put your plant in a pot of ground up plastic could it take up any nutrients from the plastic? No the only nutrients would be from the water you gave it and what is included in your water.

Your plant is now larger and needs more nutrients than what most tap water provides. So how will you know if your plant improves? You see once a leaf is damaged it will not repair itself. The only improvement you will see is at the growth tip(s). But if she's literally getting 200 PPM or less (seedling stage food) you won't see any growth, she'll just continue dying.

Your plant burnt because of the retained salts from previous grows. Those salts dried, then burnt your plant at the same time it locked out the nutrients you were trying to feed at even the lowest amount.

If you aren't going to feed her put her back in new soil tomorrow and then add your MG back just don't reuse the soil.

Any of his grows frankly. bongsmilie
Frankly after reading this I decided to try one more time to get the kid to listen. Ah well I shall take my 'trolling ways' elsewhere :roll:
@xtsho @Roger A. Shrubber

Thanks for your responses.
I'll emphasise correctly the question I'm asking.

I've been informed by someone who knows their chemistry, that Si maybe able to form chains in the plant tissue, which might adversely affect a smokers health.

My logic says 1mL/10L of solution isn't enough to really worry about. But I want to be sure.
Won't be using it up until harvest if it's potentially harmful.

Yes, I think that must be it. I hope so anyway. I completely understand about the coco, I just thought it was better than leaving it in the old soil. It doesn't look any worse today after the transplant, maybe even a little better - but yes I know it has no nutrients. I am going to try to get some new soil tomorrow and will repot all the other photos, but I might just leave the one in coco and fertilize it to see what happens. I don't really want to traumatize it again anyway. I'm not sure about the autos, maybe I will transplant the young ones. It will probably stunt them but oh well, live and learn. Thank you for the suggestions.

In the UK there is a fertiliser called Tomorite. It is a general purpose plant food. Most gardening TV shows suggest it's use, for anything. If you go on the UK groups it is sneered at for Cannabis, same argument as Mr. MiracleGro up there. Yet I have been growing weed with it for years, when you call them out on it, they all fuck off, because, as with that idiot up there, they are just repeating shit they have read on the internet. I notice he hasn't been back with his expert chemical analysis.

You're expecting to see movement far too quickly even for hydro. As for transplanting I've not noticed any setback from that. Usually they droop for the afternoon after transplant but pick up the next day. However I've only been growing since 1996 so I may not have seen it yet :) I'll keep observing.

If you do choose to keep the one in coco use liquid fertilizer. Also when you start with any other inert substrate use liquid fertilizer (even if you need to dissolve dry ferts in liquid prior to watering). Measure both the EC/TDS and pH of the solution prior to use and make sure it's within the right parameters or it will be unavailable to your plants as you don't have a microbiome set up yet.

The problem you have with soilless vs soil is that they have two different watering processes. You can't treat soilless like soil and vice versa. That's why so many amended coco grows fail. It's like trying to graft the head of a dog onto a fish. It's a fraught amalgamation of diametrically opposed needs.

As I mentioned previously I have a friend with a Ph.D. in Biochemistry who can grow pot in anything (after his lifetime focus on plant physiology I'm not surprised). He's successfully used MG because he had it laying around. Cannabis is just a plant and not a particularly picky one. So use what works for you.

My mate is a Chemist. He found the concept of pre-mixed calmag hilarious. He considers a way of maintaining a healthy balance between the rich, stupid and/or lazy. He showed me how to mix my own using Epsom salt and calcium chloride. Then we worked out a schedule/ratio we could give it at, based on the PPM of my tap water. For about £12 ($10) I have enough CalMag to last for years. My plants are better for it too, we are encouraged to give way too much CalMag. I use Plant Magic Oldtimers Organic and they sell "Organic Magnesium" (aka Epsom Salt) at a silly price, they want you to give at the rate of 1g per litre with every feeding, it is no wonder people get salt build up.
