Second week.
Around day 7, the color of the leaves is somewhat yellow. I gave a light feed of cal max (0.26 EC)
Day 12, it is both transplant day and TOPing day. The leaves are looking kind of sad and discolored; plant is becoming rootbound.
I gave the plant it’s second feed, much stronger than I would feed on a pre fertilized soil (0.9 EC), lets see how the plants like it. I think I should have started feeding earlier.
@Fast_Buds, I made a mistake when uploading the photos; from week 4 onward I confused the strain with another one. This is now solved and makes sense, since the Crystal Meth is the only one that could have the purplish / black colored buds.
