Original Sour Diesel - coco grow

Light power consumption: 102 watt Hello fellow growers! The biggest challenge this week was fertigating the plants enough times per day. The girls started to drink significantly more and after 24 hours without fertigating, the pots felt really light. Hence, I needed to fertigate at least twice a day, preferably three times a day. I tried to do it twice a day, but unfortunately, between day 20 and 21, I failed to do this and there was about 30 hours between the fertigation events. Immediately a magnesium deficiency became manifest, with interveinal chlorosis in the older leaves as a telltale sign. To be honest, earlier in the week I already noticed - ever so slightly - the same symptoms, but it seemed under control. Missing that second fertigation late in the week just escalated it to a real deficiency. Ulrika en Vivian (the ones in the smaller pots) are struggling even more with my failure to fertigate frequently enough. They grew slower than the others and became droopy. No problem, as I planned to flower only the three best plants and those are in the bigger pots. To temporarily mitigate the magnesium problems, I fertigated with just CalMag and Terra Aquatica Silicate, which also contains magnesium, at EC 1,1 mS/cm and pH 6,2 on day 18 and off course again on day 21. However, the real solution is to fertigate more often per day and/or transfer to bigger pots and today, day 22, I did both and hooked the girls up to my automated fertigation system. This will be covered in the following update. Besides trying to fertigate often enough, I also pruned the shoots from the first and second nodes on day 18, as I’m going to manifold/main-line. Next week, shortly after transplant, the girls will be topped. And last: the girls are starting to smell a lot, especially for their young age. That’s promising! Thanks for visiting and happy growing!
