So I looked up Plant Magic soils and nutrient lines. They have one product that uses the word soil.. It says it's a mix of peat, fytocell foam, and an organic growth stimulant. That's technically not soil.
It's seems to be listed as a growth medium. I've never grown with fytocell foam.. From what I've read about it, it has a ph range of 5.5-7. It doesn't list any of buffers.. Some sites say it has enough nutrients out of the bag to get through the first 30 days or so... So Im not familiar enough with the product to safely advise you on how to correct the possible issues. I think Plant Magic is popular in the UK area.. Im not sure if it's available here in the USA. You can do a site search for "plant magic" and take a look at any journals from uses that use plant magic. Perhaps they would have better insight. I'll do the same and see if anyone can help.
Thanks for taking the time to help ye it’s a uk company the guy at my local hydro store said it’s similar to the Biobizz range And the fytocell foam is a sustainable substitute to perlite. I will post the description of the soil listed on their website it is quiet long lol sorry in advance
Plant Magic Soil Supreme is a peat based potting soil mix, with a small but significant difference to most other potting mixes currently on the hydroponic market. It contains the usual blend of all-natural ingredients such as black peat, white peat, rich compost and growth stimulants, but it’s key area of difference is with the added phytocell it contains. Fytocell is a 100% biodegradable product that drastically increases the aeration and drainage properties of the potting mix. This means you get all the benefits of a peat based potting mix, but the extra aeration of the phytocell increases root development and performance, meaning a stronger, healthier and an all-round more productive plant.
It is lightly pre-fertilised to an EC of around 1.2. Beginning at this level is ideal for establishing plants in when initially transplanting. Easing plants in with a lightly fertilised substrate is the perfect way to start a plant off, avoiding any potential issues with overfeeding and/or burning leaves. It also gives you the option of adding liquid fertilisers to your irrigation regime earlier, giving you more control over the nutrition your plant receives – leaving nothing to chance!
Suitable for almost any indoor hydroponic grow room, Plant Magic Soil Supreme potting soil is perfectly suitable for establishing younger plants/seedlings to grow on to exceptional organic flowers.
HOW TO USE PLANT MAGIC SOIL SUPREME
You can use Plant Magic Soil Supreme on its own, straight out of the bag. Once you have transplanted into the soil, there is enough nutrition for growing a healthy plant for up to 2 to 3 weeks using nothing but water! It has been produced to work in perfect harmony with the entire Plant Magic range this makes the perfect formula to establish a young plant into a healthy specimen.
Alternatively, it makes for an incredibly useful starting point for creating your own unique potting mix. As it is lightly pre-fertilised, it makes an excellent foundation to add other organic inputs such as Insect frass (
Ecothrive’s Charge) or Bat Guano (
Plagron) for those of you who like to hand craft your own unique organic potting mixes and tailor your mix to your own plants requirements.
While you can use the product straight out of the bag, if you take the time to apply a little more effort in preparing the soil, it will make a significant difference to how well a plant responds after transplanting. Ideally, moisten the media slightly and store in a warm place for around 36 hours before using it. This activates the microbial life in Plant Magic Soil Supreme so they can get to work from the very first moment you plant out into it. Beneficial bacteria and fungi are essential in an organic environment, helping with nutrient cycling, promoting healthy root growth, warding off unwelcome pathogens and diseases and helping the plant with drought stress.
Once the soil is prepared, make sure you fluff up any compacted lumps of media in the bag. During the transportation process, it will become compacted slightly so you need to ensure you break it up as much as possible. When filling the empty pot, do not compact the soil down while transplanting. You want to make sure you have the ideal amount of aeration and drainage throughout the entire pot. Tap and shake the pot while you are filing it to ensure the media settles evenly rather than compacting and forcing it down.
HOW TO FEED
Plant Magic Soil Supreme potting soil has been designed to work in harmony with their full bottled nutrient line, either the old timer organic range, or equally well with their mineral line. It does not contain a lot of nutrient (EC 1.2) so (depending on plant type) you will need to begin to use a fertiliser after the first week or two. During this initial period, Grow or Bloom nutrients aren’t necessary but you will still benefit from the addition of a rooting stimulant from the Plant Magic
range.
The potting mix is also pre-buffered for pH with a liming agent so no need for any expensive pH meters either! The liming agent that is used in the potting mix automatically corrects any pH variations in the substrate back to the ideal level. If you choose to re-use your media, then it may be beneficial to use some dolomite lime each time you re-use it to ensure the pH buffer is still present and correct.
When watering your plant, try to make sure you do it at a slow and steady rate. This will make sure that pot is evenly saturated throughout, and the solution hasn’t just taken the path of least resistant straight back out the bottom of your pot. Feel the weight of your pot after you have irrigated and wait until it feels almost half of that weight until you irrigate again. If you leave it too long between irrigations, the peat may struggle to re-absorb the water, almost becoming water replant. Use a wetting agent in this instance to stop water pooling on the surface.
TIPS WHEN USING
Although there are beneficial bacteria present, you can never have enough of a good thing! Using beneficial bacterial products like
Ecothrive’s Biosys, can help boost performance when using Plant Magic Soil Supreme.
Do not plant out into too big a pot of soil! A large pot will stay wet for too long for a small root system, make sure you go up pin pot size at the appropriate rate.
For best results, always follow the Plant Magic grow guide, but always remember to respond to what the plant is telling you as well.
.....I don't have to adjust my feeds as they're around 6.2-6.5 on their own( currently using synthetic nutes) but every time I swap nute lines I always check just to be safe(even with organic nutes) 
.....see a lot of grows round the place go tits up from not checking ph
.....idk how to lift the inpot ph without having to worry about anything else screwy happening....?....maybe proph does? He's definitely more switched on with this stuff than me
