Crystal White Kush on Coco 12/12 from seed Super Sativa Seed Club

So I am planning my next round.... This time my first single strain diary. I received 15 seeds from Super Sativa Seed Club to make this happen. Nice packaging, not my first SSSC strain (currently growing Lava Freeze). Since it is a single strain I am going to try to make it a low maintenance round. 12/12 from seed, single nutrient (allright and a bit of CalMag) and Blumat drip-system. Next Friday I will put them to germinate as soon as I have my newly ordered nutrient. Please give me some tips for the nutrient (locally available The Netherlands), not separate bottles for grow and bloom, must be able to keep fresh for 2/3 weeks in container (with circulation) and preferably no need for boosters or anything. Today I am putting the seeds in the soil after a 24 hour soak in water (bit of peroxide). All seeds opened :) All of them are put in 5.6 litre containers for the first 3 weeks because of lack of space and I want to partially reuse the coco from my current run. Lighting scheme is 20.00 lights on, 08.00 lights off. Starting with 360W of power at 130cm height. As soon as the other round is harvested I will move them to this space and continu growth with 1500W for the rest of the run. Since it is a single strain grow and 12/12 from seedI don't expect any difficulties with nutrients as in my current round. 27/7: Small change in the plans... The pots don’t match the rest, so they’ll stay in a tent for the next three weeks. Hopefully, they won't grow too big. I’ve sorted the seeds. I chose the ones with the longest root tips, although the difference is minimal. The remaining seeds are in the top right. 100% germination... thank you SSSC! Now everything carefully goes into the coco. Nutrients consist of 5ml/L Cocos A+B, 0.8ml/L Calmag. 600ml nutrient solution per 5.6L pot. No idea how long that will last, so just to be safe, I prepared a total of 10L. Measured pH 5.9, EC 1.4. Tonight, I'll just hang the lamp above and install a small fan. During the first three weeks, you won’t smell them, so it’s solely for circulation and heat dissipation. 30/7: 11 out of 12 are showing their heads. As mentioned I have 3 spare seeds, put one of them in the empty pot. So hopefully it comes up. Otherwise... 11 it will be. 31/7: A bit stretching but not sure if it is too much stretch. Will determine tomorrow, I like the current height so if they start developing some leaves without too much stretch I won't lower the fixture but when they do I will just have to. I will count next Saturday as day one (first week vegetation). Since I started on 12 hours I will just call them vegetation weeks as long as there are no signs of flower. 02/8: Totally unexpected the 12th seed came up.. So Monday will be day 1 veg..
