Nute Burn From Soil In Veg

Hiya everyone, just thought i'd show some pics of nute burn not from adding nutes but simply from the high levels of nutrients that some soil companies add to their soil mixes. I think that this can throw of most new growers in soil and what i see a lot of questions on. I am no pro grower but have done it as a hobby and for fun for few years now. I embrace small scale and natural grow methods prefering low-tech and simple. I use westlands soil with biobizz grow and bloom although you won't find me adding any fertilizer to seedlings (which are always started in a peat cube or jiffy pellet) or plants in the veg room for that matter, the only nutes they need at these two stages can be got from the soil. Now some companies like foxfarm etc might produce more specialised lighter soils that require fertilizing after a mere two to three weeks but for the rest that purchase seedling soil/compost like mine made by westlands, b&q, homebase, most major supermarkets and the worst by a long shot 'MIRACLE GROW' you need to realise that these are companies that really do add enough fertilizer to last at least 5 to 6 weeks and as you see i don't use very big pots for my veg time either. Anyway here are a few pics to hopefully give you a guide of what to look out for and why you sometimes don't need fertilizer when vegging.
Pictures 1-4: Here in pic1 is my grow room, nice and simple with a four bulb t5 2foot long lightwave unit with a small pc fan attached to circulate air and dissapate heat although these t5 lightwaves burn pretty cool and don't really need cooling much. In pics 2-4 you can see my plants doing nicely in the veg period, all grow fast and strong. Notice purple colour to the plant stems and some leaf stems as this is the first sign that the plant is getting just a little stressed from the nutrients present in the soil, if your plants only ever get that bad then don't worry as they will grow out of it as they get older and stronger, more able to deal with the nutrient strength of the soil.
Pictures 5-6: Ok so in pic 5 is what you might think is a nutrient deficiency but you would be very mistaken. The seedling is showing a slight yellow margin to the outer edges of the leaf and especially to the tip. Notice how it is the bottom leaf that is affected and the new growth is ok. The new growth might end up burning and yellowing too but in this case i know the seedling will green up as it was a bit more yellow as a small seedling and was greening up before i took the photo. Most of my seedlings show a small amount of stress from the westlands seedling soil by either purple stems or yellowing of the leaves, please don't think it is lacking in nutes and fertilize, the soil got them nutes in it already and the seedling is just learning to deal with it. Fertilize at this stage in soil and you kill your plant, roots haven't even grown into all parts of the soil yet! On to pic 6, i added a small amount of fertilizer to show what fertilizing at week three of the veg period in a lot of soils will do, the plant has been flushed after the deficiency started and is now growing strong although it took a week for the plant to resume normal vigorous growth and stunted itself a little. This was achived with a very light dose of biobizz grow and even thats organic. Just goes to show that the soil is still providing the plant with everything it needs in week 3 and 4. Notice the big ridges on the leaves, the mega dark green colour and the yellowing of the leaves which turn dry and crisp, over fertilization!! The leaves can also fold up at the edges, turn like a corkscrew and even just go brown and crispy. Really guys you don't need to fertilize a lot of soils thesedays.
Pictures 7-8: Ok i grow short plants that i top after the third or forth set of leaves and train four main branches. The plant in pic 7 and 8 is ready for the flowering room and was transplanted to this bigger pot at about half way through week 5. It has never had a single fertilize or nutes except that which was in the soil when i bought the bag and spent 5 and a half weeks plain tap water in the smaller pot no problems. I prefer to wait till the plant does start to show that it needs a feed before i transplant into new bigger pots, kind of like giving it a feed when you give it new soil so in the new pot which has west compost i will not really need to feed for 5 to 6 weeks again or probably half way through flowering. This plant is happy, healthy colour, rapid growing and bushy with enough nutrients in the soil to last it a while with just plain water. !! Point to note here is that the same scenario might happen again in flowering, the flowering compost which is stronger than the seedling compost might cause the plant to stress a little and the it will probably show signs of over fertilizing again, please don't add nutes but rather flush if this happens. The same that happened in the veg room could happen in the flowering room with new soil and if i fertilize i'll kill the plant. With this size pot and going into flowering i got at least 6 weeks before the roots grow through all the soil and take all the nutes out and then and only then should i fertilize.
Pictures 9-10: A real passion of mine is growing any plant, love it and the same principals go for most the same as the marijuana plant! Marijuana is not some super growing plant that can do anything, it is the same as most plants, give it the right conditions and you'll notice the growth everyday. It dose not need super doses of fertilizer but the same amount as any plant that is a similar size and weight. These here are Jalapeno chilli pepper plants grown the same way as my ganga in the same soil with no fertilizer. These chillis can take upto 20 days to sprout and form a seedling wheras my mj plants take under a week. These chilli peppers stay real small for the first four weeks then grow like crazy wheras my mj grows like crazy after just a few days being a seedling. This jalapeno is probably 7 weeks old now and grown entirely under one 2ft t8 flourescent bulb near a window but never gets direct sunlight.
Honestly be warned in soil it does contain a lot of nutes and for most of the grow if you repot when it needs a feed instead of fertilizing. I know some have very good soil that isn't so strong but most are and especially the comercial ones. Coco coir and perlite will weaken it more for you if you find it is still too strong. Most times i get soil it is on the verge of being almost too strong and i find myself doing a flush at week three of the veg just too correct it. Miracle grow growers are doomed, timed realesed fertilizers are a great idea but not at the strength at which miracle grow add to their soils and rules out being able to flush nutes out because more will get realesed at the same time. If i used miracle grow i would definatly weaken it first with coco coir and probably be the last thing i did if i added fertilizer.
Please realise too that heat stress and overwatering are two more very common problems that will sometimes look like overfertilizing and not to get confused as to wether it is a heat problem/ soil nute problem or watering problem.
Very confusing this marajuana growing but keep it simple as i do and you'll be ok. If your wondering about the tin foil on top of the packs and the little green and white packets on or by the stems well these are to control thrip which i get now and again during summer months so i get in before they first arrive with covering the pots to stop the thrip larvae getting to the soil (this also keeps the soil evenly moist notice roots grow upto and along the surface as well as down from the plant stem/stalk allowing me to plant deeper when repotting and thus reduce height by a few inches) and the packets have little bugs in which populate my plants doing no damage apart from eating the thrips and spider mites if any happen to wander in from outside. Thanks for listening.

This is why people don’t take time to post. People just want a quick fix me till the next problem. The dude past away stop shitting on him.
imagine home much time that took to put together and you’re shitting on it.
What do you do? Learn by the expert "master growers" who put out Youtube videos full of unhealthy plants with misguided and outright incorrect advice?
Some people in the newer generations have devolved as a species if they are incapable of reading a few paragraphs of text for information.
