Muyoso I think your confused. A good soil grow does not use a soilless mix. I grow in soil and use a organic blend of FF ocean forest and a local orgo soil. Unlike a grow in a soilless mix you do not need to fert regularly. I am currently in 1st week flower an have not added anything to soil but PH'd water and they are going great.
I dont disagree with the fact that people burn seedlings, seeds have a food supply and dont need nutes for some time, Clones consume stored energy in their remaining fan leaves. Plants grown in soilless mix however require ferts soon after planting, like salty said it has one feeding in it but then ferting should commence. Hell, on the bag it says you should start a nute regimin after 7 days.
Oh and the HTG is the guy at the counter at high tech garden supply, where half the guys here in the US get their lights. Im not saying he was giving me anything other then quick advice, but I wanted to start seeds in soilless media and he said I would have to start ferting early, like hydro, if I went the soiless rout.
Sorry to offer some corrections but you make me sound like an idiot that wants ppl to use MG, not that there is anything wrong with that, however when you tell a dude not to follow the instruction printed on the bail of pro-mix I feel like you need to provide a little more information of why that is so.
PRO-MIX 'HP'is a "High Porosity" professional growing medium designed for the cultivation of horticultural greenhouse plants. During the course of crop production, it is necessary to initiate a fertilizer program. The fertilizer program selected should consider water nutrient content, crop type and stage of plant development. It is essential to begin fertilization within 7 days after planting and maintain fertilizer applications throughout the course of crop production. To insure plants receive proper nutrition, it is advisable to periodically analyze fertilizer solution, nutrient content of growing media and plant tissue throughout the production cycle
Your right...that sounds so much like "drop in the seed and water" not like hydro at all
