Fusionanswered grow question 4 years ago Agree with made in Canada, but we're both in same country.
With me I start on the 3rd week ruffly. When the "true" leaves develop (7 points) . Start with half recommend dose the first time, next week just a bit weaker than the recommendation, by then can see how she responds.. if any yellow tips, purple stems on shades , ect.. I watch the stems and aim for small purple line on under side when I increase/decrease. 5-7th week of bud I hot dose, then I flush 8-9.
