FastBuds Galeto Auto - New training try

First of all, sorry if my English is not perfect. I will do my best Secondly, I am in no way a PRO grower, I have done some growths, but I never put much time in it, and the result is usually good (with room for improvements), but the yield defiantly suffers in my opinion, and now I want to learn, and explorer different methods to improve the yields, and perhaps the quality. I have improved my soil, by adding about 20% perlite and 10% coco coir. In my previously growths, I used BioTabs ONLY (nothing more then the tabs you put into the soil), and I still have quite a few left, so I bought the starter pack from BioTabs with everything they recommend by their manual, to use for my current/future growths (At least the auto strains) and will properly look into other nutrients when I have used up my BioTabs For this grow, I am also going to try some new techniques. The plan is: Whenever they are about 2 levels high (Around start of week 3) I plan to replant them all into 20L pots and top them. After a week or so I will try for the first time to do Main-Lining (Fingers crossed I succeed). Slowly after that I will do some LST (Also for the first time), and at some point, I also plan to do some Defoliation. There are many new techniques I have never tried before, and I hope to learn them by running this grow. The soil I use for this grow is properly not the ideal, but it have worked for me serval times. The soil is 70% sphagnum and 30% wood fibre. PH = 5.8 - 6.6. Degree of humification: h5-h6. EC: 25-45 mS/m It contains the following minerals and nutrients each cubic meter: Nitrate-N 52g, Ammonium-N 88g, phosphorus (P) 70g, potassium (K) 149g, magnesium (Mg) 5g, Boron 0.3g, molybdenum 2g, copper 1.2g, manganese 1.6g, zinc 0.4g, iron 0.9g. Any advice on picking the right soil is very appreciated! The germination method I used was paper-towel, and it went surprisingly fast. Around 36 hours later they where sprung out, and I planted them in small pots, maybe under 1L (Day 1 picture) Now the plant has begun to show it self :) (Day 4 pictures) Day 7: All plants looks good and healthy, yeah! Good start. They tend to be a little high, so I have placed the light a little closer :)
