2. Runtz seed did not pop up after a week, So I decided to soak another Runtz seed, that germinated after 3 days. So I transferred it today to its location at the top right.
I saw that I used the wrong fertilizer Hakaphos Blue (15-10-15), which is for hard water. Next time I will use Hakaphos Ultra Soft (18-12-18) for soft water, or I mix them because my water is 3 parts tap water and only 2 parts RO water. Maybe this is why the leaves look somehow light green.
Since I put too much PH-Down I had to correct it with Kaisernatron (Sodium bicarbonate).
PH is between 5,5-6,5
EC is now @ 1,1mS
Edit: End of the Week I added Silic Boost from ATAMI 1ml/50l and 2g Hakaphos Soft Ultra.
