Hindu Kush Automatic

day 36: a new week for the ladies and they are definitely in bloom now. Currently they are still only getting RO water with some calmag (to 0.4 mS) added, and the pre-fertilization from the Plagron royalmix seems to hold up fine.. it's supposed to last 6 weeks and so far so good, but obviously this means i need to keep a closer eye on them, for being able to jump in and start feeding them, once it's been used up. The blumat-tropf system works great. day 37: since the lower leaves start yellowing very lightly, this indicates to me that the prefertilization of the Plagron mix is slowly depleting, so i have changed the water in the blumat-reservoir from RO/calmag only to a proper GHE nutrient solution, with AN additives.. EC i set to 0.8, PH 5.9. They advertise with the mix being pre-fertilized for 6 weeks, so that's pretty much right on point. also the White Widow that had initially shared a box when they were young, and has reunited with them last week in the tent has reached maturity and has started to pre-flower (it was a non-feminized photoperiodic seed) and has shown that she's a female! day 39: i have noticed some brown flakes inside the reservoir, and i believe this might have been due to the sensizym (if not that, then definitely one of the AN additives mixing with the rest, or letting it stand with the air-bubbler for a few days), so i decided to mix a small batch of base-nutrients with the AN additives and manually water them 250ml each (total EC 0.7), and only put the base-nutrients (GHE/calmag) into the reservoir for the blumat-system. (This time with EC 0.8, the next change will be raised a bit). day 41: It seems pretty clear to me that the Plagron nutrients are almost depleted. Given that it's my first grow with Plagron royalmix, I knew that once it'd end i would have to test a bit and see what EC i need to feed them with now. That'll just be trial and error and to slowly raise it up. Also i did some light defoliation.
