Hello.....well this is very heartbreaking for me. I planted 6 plants into 20 litre airpots using a mix of 60% plant magic soil supreme and 40% biobizz all mix. I made sure the soil was put into the pots nice and loose so there was air and no big hard lumps etc. I then gave each of the pots a good watering untill the was some runoff as i reckoned i probly still needed to flush some of the nutes out of the biobizz all mix and thought it would help bring the soil "to life".
After this i placed my root riot cubes where i started the seeds into the soil. The soil didn't seem hard it was really easy to make the hole. Now these were left unattended at another location with insstructions to give a little water when they were starting to dry out. Well i suspected they were being over watered because the few times i checked the soil was pretty wet and it wasnt just around the plant it was all the soil and this was like a week later. The plants grew fine for a week then all progress seemed to stop.........and the leafs started to get yellow patches on them and curl down a bit. Well almost 3 weeks later and they looked the same size and even worse condition then something in my mind clicked.....the soil looked pretty compressed compared to the plant im growing at home wich used the same soil mix and had been treated the same way.

The ONLY difference between the 2 is that i realised i made the airpot upside down and repoted my plant to fix it. I remember still having a couple of handfulls of soil still left over after i repotted it but it wasnt a huge amount and the soil was still nice and fluffy. Something in my mind clicked.....was like a flashback image of the 6 plants sitting there.......the soil looked like it had sunk down below the original level it was at when potted. So i went round and checked it and i could hardly even poke my finger into the soil......i unwrapped the airpots and exposed the soil and started to break it up,it was really stuck together it was almost like a sponge. We repotted all the plants and we had a tonne of soil left over even though they were fillled to the top! And the roots had hardly even grown at all and the ones that did were really really thin.

Where did we go wrong here? And can these plants make a significant recovery to be worth a harvest after this amount of time or is it doomed? I'll show you all some pics of the 6 that are looking bad at week 3.

For comparison here is my plant wich was started at the same time same soil etc.

Heres one more pic of the compressed soil situation before i repotted them all. This was 12 days ago aswell.......they haven't grown much at all......

Being over watered and then transplanted are two of the worst tthings you can do to autos.You could try and get some mychorizae and mix some in your intake water that has been ph'd and hopefully it wll kick start your root system.Other than that only time will tell if they will come back but it will be slow.

Well im keeping positive since you at least say time will tell and not that "its all over and start over again" because i can't start it again they need to be finished by the begining of March thats the time limit i have for the tent grow. I've seen alot of you mention that mycorrhiza stuff and im going to give it a go!

Soil is too hot for them.

Yeah i noticed that when i was growing my personal one in the closet it has a bit of the nitrogen claw thing going on. I should have mixed in more of the plant magic stuff into the biobizz to dilute it more. It seems that because the soil was so compacted the roots were having to try really hard to get through the soil and weren't managing to penetrate it wich kept the plants small and also held in more moisture and then more water being added.......not good. So the plants are still tiny and because of this the hot soil had started to cause burning of the leafs. On the other hand the plant i have in the closet is in exactly the same mix of soil but because the roots had access to air and could easily grow through it it got big quick and ended up being able to withstand the hotness of the soil......no burning on those leafs at all. Guess this was the straw the broke the camels back so to speak. Just hope they can pull through!

Over watering will compact the soil and cut off needed oxygen to the roots. While the All Mix is too hot for autos, I would think the 60/40 mixture you did should be enough. What I would suggest for your next grow is mixing in some perlite. I know the Plant Magic contains Fytocell foam but it doesn't look like near enough. That foam serves the same function as perlite, keeping the soil loose and allowing for more air to reach the roots. Without enough the soil will compact a lot easier. Perlite should comprise about 20 - 25% of the total volume of your soil mix.

Also, when posting pictures please turn the LEDs off and use either flash or natural light. That way we can see the true color of the leaves which is very important when trying to diagnose plant issues.
 
Sorry about the pics i'll try and get it in a better light from now on! Do you think these plants can come back to health and be a decent size or will they be forever stunted midgets?
 
Have they started to pre flower yet? If not, you might get a little more veg growth but usually if they are stunted that badly they won't get very much bigger.

I don't think they have pre-flowered yet but im going to go and take close-up pics A.S.A.P in natural light and see if they are or not and if they have improved any. Im hoping for a miracle recovery in like a week lol.This wouldn't be a big deal as i have tonnes of seeds but the place im growing it cant be used for any longer than the start of march aparently....i'll see if maybe i can get them to extend that a little and start from scratch and this time add the pearlite in! Thanks again man!
