Sour Diesel Time-Lapse

Exactly a week ago these five Sour Diesels were planted. The sixth plant you see in the pictures is a CousKush Auto that is being nursed for 2 weeks to then be taken care of by family. They germinated quickly, after less than 72 hours most cotyledons were fully open and the roots grew through the root cubes. At this point they were transplanted into 0.12L seedling bags filled with pre-buffered coco and perlite (saturated with PH'd RO water). They will stay in those to develop a good root structure for around a week before moving to 1L pots. They reacted decently to the transplant although the cotyledons curled down on some of the seedlings. I attribute that to the coco being too moist when they were transplanted. I waited to give them more water until day 5 to dry the coco out a bit. Day 5 is when I first watered them, using a 0.3 EC nutrient solution. They all get 8-10 ml every 24 hours now and seem to be doing great.

This week did not go too well. The plants started being more and more droopy and barely grew, which you can clearly see in the time-lapse. I initially thought they were sitting in coco that was too wet, but drying it out did not help their case. I had already wanted to transplant them at this stage, but didn't have the right pot size available yet due to a late delivery. Then, at day 13 from planting the seeds, I received the pots and immediately went on to transplant them into wet buffered coco in 1 liter pots. They instantly recovered and have been doing great ever since as you can see in the last picture. Starting from the transplant, I have been feeding them with 0.5-0.7 EC water, a bit more than half of that made up of calmag, the rest coco A+B and rhizotonic. One is showing a slight calcium deficiency, weirdly enough. Especially as the coco was buffered in a 1.2 EC calmag solution for several days before use. Will keep an eye on this and might give some extra calcium as a mono nutrient. For now, next week looks promising. This update is a little late, so I can tell you that by next week's update they will look much better.

This week went a lot better than last, although still not optimal. After last week's transplant they all did well, as you can see in the time lapse. They do all have one or more deformed leaves and a slight calcium deficiency but look otherwise healthy. Increased base water (RO+calmag) EC from 0.3 to 0.4, feeding 0.7EC in total. At the end of the week, the root systems looked very well developed and I transplanted them into their final 5L pots. Decent so far.

They didn't show any transplant shock after the transplant to their final pots. They do all show increasingly bad signs of calcium deficiency though. I'm going to give them a feed consisting of at least 0.5 ec of calmag in the next week. At the end of the week, I moved them to the flower tent in preparation of flipping them. They are now on a 18/6 light schedule. First days didn't look too great, seems like the humidity in the room was off.

The calmag issue went on, so I kept adding a bit more every time. All the new growth is looking strong. This week was also time for their first LST. First at the start of the week and then again at the end of this week. They seem to do well.

This week they are all booming after continuous LST. The calmag issues went away after staying at 0.4 ec for a while. All new growth is looking good. Starting adding Cannazym to get rid of any dead roots that have been formed around the edges now. The time-lapse for this week is only for the last few days as I had some technical difficulties. Still feeding at around 0.7 ec total. Also added more fans this week to circulate the air better. Three run every 30 minutes for 3 minutes to blow out 100% of the dead air from the canopy. Another fan is blowing continuously. They start to increasingly smell now. Very strong yet subtle right now. Oh and in case anyone noticed: One of them was a mutant (very weirdly placed growing nodes and other unusual behaviour) so I had to throw her pre-emptively. The rest of the girls look ready to for the ride though!

Another week of LST. They all look slightly hungry so I've upped the EC to 0.8 this week. Some plants are starting to get ahead of the others now. One is especially looking kind of weak, but in my humble experience it will probably turn that around and produce some great bud :) Slowly decreasing the light hours to prepare for 12/12. Bringing humidity to 60% levels. At the end of the week they looked in great shape. No time lapse this week, lost the file somehow :(

Decided to flip to flower this week. Ramped up to 1.1 ec before flipping. Probably a tad too slow since they look hungry. Will slowly increase. Did some more LST to widen them up a more during the stretch. .

Ramping up the EC continued. 1.2 for this week. It is increasingly hungry though so I need to find the balance for how much to ramp. I'd rather go a bit too low than too high though so taking it slow. Flowers have appeared and are slowly starting to develop. A subtle and very delicious smell is starting to develop. Also since last week they've been drinking a lot more obviously. Been giving around a liter a day each. Once a week a lot less to dry them out. Did some LST again as I wanted them to cover more surface. Lets see how next week goes.

Gone to 1.3 EC. Flowers developing in length. Got some issues with heat during the week. The weather here is increasingly hot and I don't have active cooling in my home. Tried to keep temps down but with the temps outside the tent at 25+ celsius is hard. They don't seem to like it much. Looks like they have trouble taking up nutrition.
