First try Kannabia seeds - Colombian Jack

Hello mates, third week week of vegetation. Colombian Jack reacted well a week after topping (10/10), she had a good growth in all branches that increased thier dimension but they didn't stretch a lot despite i had pruned the two lower two day before. She has a structure that remind me more an indica strain than a sativa, as you can see she has big fan leaves with few tips and for now a bushy structure. Badly in the 11/10 i noticed the tipical sings of Ca defiency in the lower fan leaves most on Colombian than on the other plants in the tent so this meant i did something wrong with my Ca/Mg rate in the base water. I checked again how much grams of Epsom salts i must put in the base water and there finally i found my fucking mistake, i was 10x wrong about the unit of measurement. I always put 0.2 g/L of tap water and this was the mistake because i should have put 0.02 g/L, I completely reversed the problem of the tap watear that normally have more Ca than Mg. Anyway Colombian had a good condition and a good growth in fact the last day of the week i did a defoliation and pruning in the lower part of the plant.
