First Grow - Classic F1 Auto White Widow

After a first outdoor attempt last year and failed big time, I build an indoor DWC growsetup. Will post more pics during this grow.

I've put 4 White Widow Classic F1 Auto in Cultilane blocks. Hope to get some help during my first grow! Once the roots start to pop out I'll start the nutrition program.

Hope to get some feedback about nutrition : After 1 plant developed a small brown tip, I started feeding. A total of 116.6 liters of water goes into my system. The feeding schedule says that you should give 4 ml of root juice per liter of water. So: 116.6 x 4 = 466 in total for week 1. So, 466/7 = 66.5 ml per day. Despite this, the differences in root growth per container seem very different. 1 bin was so far behind that I changed them. However, after 1 day a brown mass developed in the roots. The others are still nice and white. Is this already the bereft root rot? I've made some pictures and a video. The first plant in the video was first in the container of the third plant in the video. EC value = 0.6 PH = 6.6 Update 3-5 : After adding more air, problem solved. Need to keep an eye on plant #3. I've put sticks on top of the startblock. 1 stick is plant #1 etc. Plant 3 is behind the rest. Root development also differs from the rest. Instead of a long (about 50 cm) long carrot, they are a few short (10/15 cm). The plant is also significantly smaller than the rest. Can't do much now so, let's hope and see she can catch up.

*ADVISE NEEDED* The day before yesterday I discovered a huge error in my system. I placed filter material in the feed-throughs of the breeding boxes. This is to prevent the roots from growing together over time. However, what I caused with that is very difficult to explain. The bottom line is that the distribution of food and circulation was actually not good at all. This also explained the differences in the water temperature, but also PH and EC values. That is now completely under control because it now runs stably for 2 days. However, you can see that the records have had a bad start. I am thinking about starting over. Week 3. Week 2 was looking for the correct settings for my system. I found out that the temperature in the bins is quite different. When I set the water chiller to 19 degrees, it all flows fine into the first container. There it rises about 0.5 degrees per bin. The margin of the chiller is about 1 degrees, causing too many fluctuations in the system, with tray 1 becoming too cold and the last one too cold. I solved this by shielding the box at the inlet of the tent with heat-protective foil. I also put a fan on the water chiller. If that catches on, the entire loft heats up, whith more fluctiations. However, I have enough space to measure very precisely and I am getting more and more control. I think the brown leaves were the cause of much too hot water. Since I have the water temperature under control, I see that the new leaves are growing nicely. Moreover, since yesterday (13-5) I received the nutrition. 10 days late. I just finish the root scheme I think. That is still 3 days a 70 mm per day combined with BioBizz Heaven. I tried to take some pictures of the roots and some close ups. I hold the lid with my left hand and with my right hand I try to take a picture zoomed in (max). While the wind makes the roots dance past my lens😵 Something different than usual ... Hope you like it. If you see something that needs to be addressed, let us know. It is my first breeding so there will undoubtedly go wrong. This week I also connected the water reservoir with which I can flush the entire system at once. With this I also control the Ph in the system. Will post photos soon.

Week 4 update. It has been very busy lately, so I have been able to spend less time on the plants than I wanted. Nutritions well maintained. It has now become a collection of different types of growth. 1 plant grows up very wide and high and is already in bloom. The other is more elevated and is now also in bloom. The third bumps a bit behind it and only has some signs of pre-flowering but no buds. The smallest does quite well for its size. My idea is to use 3 different techniques now. For the 2 largest a scrognet. The other, second largest, I am not finished yet. Maybe make cuttings? And the smallest, I want to have 1 big top. No idea if this is possible in 1 tent but it seems fun. I keep the light schedule on 6/18. They are doing very well.

I've stopped this grow. To much errors. But what a ride it whas. Learned very much. Next grow here we come.
