Jack 47, UK grow

This is the first time I use seeds from Sweet Seeds, and so far are the best seeds I ever used. I soaked 2 seeds in water, then I put the seeds inside a paper towel and after 2 days I put the seeds in the soil. I'm using a mixture of coco and perlite, around 55% coco, 45% perlite. I only have one light turn on at the moment, at this stage is more than enough, in the future when the plants are big enough I will add the other light. When I put the seeds in the soil, I sprayed tap water on the top layer of soil, the first couple of days I didn't open the vents on the tent, and my exhaust fan was turned off as well. On day 4, with the vents open and the exhaust fan turned on I gave the first feeding. Around this time, I also turned on the oscillating fan slightly about the plants, to have some air movement around the plant, the fan is not pointing directly to the plants because at this time they are too fragile to withstand the power of the wind. DAY 4 - Nutes PH-5.89 Solution Temp-19.6 Watering Volume - 0.6L DAY 6 - Water PH - 6.08 Solution Temp - 18.8 Watering Volume - 1.5L At the moment Plant A is slightly bigger than Plant B. Plant A is about 7cm height, while plant B is about 6cm height. The leaves on Plant A are slightly more developed than Plant B as well. On the germination of the seeds is was clearly visible than one seed developed faster than the other one, I let the seeds stay one extra day on the paper towel because one of the seeds was not developed enough to be put in the soil.

This was the second week of the grow. I consider the first 2 weeks, seedling stage, the next week I will start the "true" week 1. During this week I didn't found any major problems, just a few curiosities. Plant A got a bit of a calcium deficiency, it's visible on the photos, it's very little damage, just on the first set of true leaves, not a concern at the moment. Plant B is growing a bit strange, the last set of leaves only one leaf as grown, the other leaf didn't fully grow. DAY 9 - Nutes PH - 6.00 Solution Temp - 19.5 Watering Volume - 5L DAY 13 - Water PH - 6 Solution Temp - 19 Watering Volume - 3.5L Things that need to improve: I wanted to find out what is the correct amount of water to give to each plant, I usually water until I see a bit of water coming from the bottom of the pots, I found out that 3.5L per plant at this stage is definitely too much water for this stage, in the past I've been doing manual watering, but I can already see that for this one I will need to set up some kind of drip system. My TDS meter broke, that's why I don't have TDS numbers yet. I think that the calcium deficiency was caused by me, I don't have a reservoir big enough to mix all the nutes, so I need to mix the nutes in batches, that causes slight differences between the batches, and that may cause problems between plants, I need to get a bigger reservoir. All of these problems will be solved next week. At the moment Plant A is slightly bigger than Plant B. Plant A is about 11cm height, while plant B is about 10cm height

No problems this week, plants growing extremely well. I got a new TDS meter, but unfortunately, I was not able to set up a drip system yet. The only training I did was to defoliate the first true leaves and everything below that. DAY 17 - Nutes PH - 6.1 Solution Temp - 19.5 PPM-1340 Watering Volume per plant - 2L DAY 20 - Water PH - 6.04 Solution Temp - 19.2 PPM-570 Watering Volume per plant - 2.5L Plant B is about 14cm Height and Plant A is about 17 cm Height. One interesting thing that I'm seeing is the fact that Plant B continues to show signs of deformity. On the video, you can see that the right side is missing a node, this missing node corresponds to the deform leaf. Maybe they are related, Plant A was slightly bigger from the beginning, but the node development is bigger in Plant B.

No problems this week, plants growing extremely well. Unfortunately, I was not able to set up a drip system yet. The only training I did was to tuck the fan leaves a bit, next week I will start LST. I used a foliar spray this week in the days that I feed the plant. DAY 22 - Nutes PH - 6.04 Solution Temp - 20 PPM-1500 Watering Volume per plant - 3L DAY 25 - Water PH - 5.92 Solution Temp - 20 PPM-570 Watering Volume per plant - 4L Plant B is about 20cm Height and Plant A is about 22 cm Height.

Plants growing extremely well, the only problem I think I'm having is too many nutrients. Plant A is showing some strange signs. a few big fan leaves are becoming "crispy" I can see a bit of nutrient burn, but a minimal amount I finally set up the drip system this week. I started LST this week, I bent both plants pretty hard, they are almost parallel to the soil. On plant A I did super cropping by mistake, I was tieing a branch and I put too much force on the bend, but palnt didn't seem afected at all by this. DAY 29 - Nutes PH - 5.96 Solution Temp - 21.5 PPM-1600 Watering Volume per plant - 4L DAY 32 - Water PH - 6 Solution Temp - 21.2 PPM-560 Watering Volume per plant - 4L Next week I will add the second ligh to the tent

This week I was a bit busy, so I don't have as many photos and videos as I would like to have No major problems this week, plants growing extremely well, just a tiny bit of nutrient burn on both plants. The drip system is working great. LST and defoliation this week, this will be a weekly occurrence from now on. I used a foliar spray this week in the days that I feed the plant, I used Mycorrgizae in combination with the nutes DAY 36 - Nutes PH - 6.06 Solution Temp - 22 PPM-1240 Watering Volume per plant - 4L DAY 40 - Water PH - 6 Solution Temp - 18.8 PPM-525 Watering Volume per plant - 5L This week I reduced the amount of nutes, because I was seeing a bit of nutrient burn on the fan leaves.

No major problems this week, plants growing extremely well, the nutrient burning problem that I was seeing in the previous weeks disappear, reducing the concentration of nutrients worked great LST and defoliation this week. On day 49 the extraction fan was off for around 10 hours, fortunately no major problems came out of this. DAY 46 - Nutes PH - 6.08 Solution Temp - 19 PPM-1380 Watering Volume per plant - 4L DAY 49 - Water PH - 6.07 Solution Temp - 18 PPM-574 Watering Volume per plant - 4L

No major problems this week, plants growing extremely well Used foliar spray this week DAY 51 - Nutes PH - 6.02 Solution Temp - 19 PPM-1430 Watering Volume per plant - 4L I only feed the plants with nutes one time, the rest of the time the plant was receiving water from the drip system. I will go on vacation next week, lets see if the drip system really works.

After one week vacation, with no supervision, I can say that I had no major problems, and the plants grew very tall this last week. The plants grew so much that I had to put my trellis net. Used Mycorrhizae this week DAY 63 - Nutes PH - 6.02 Solution Temp - 18 PPM-1500 Watering Volume per plant - 4L I only feed the plants with nutes one time, on the first day, the rest of the days the plants were only receiving water via the drip system and I had no problems.

Small problem with ph this week. I found out that one of the branches was showing problems, I found out that the ph of the water on the drip reservoir was around 6.3, I don't know what happen for the ph to change,, when I fill up the reservoir the ph was around 6. I turn off the drip system, empty the reservoir and gave ph correct water by hand and that solved the problem. This was my last week in veg, next week I will switch the lighting to 12-12. This week I used Kyle Kushman's "Chiropractic" Plant Training Method, and I'm very happy with the result. This is the tutorial for anyone interested https://www.youtube.com/watch?v=XdfW2p-lHN0&list=WL&index=29&t=1235s Used Foliar spray this week DAY 64 - Nutes PH - 5.97 Solution Temp - 19 PPM-1520 Watering Volume per plant - 4L DAY 66 - Water PH - 5.95 Solution Temp - 18 PPM-603 Watering Volume per plant - 4L DAY 69 - Water PH - 5.79 Solution Temp - 18 PPM-575 Watering Volume per plant - 4L

No problems to report this week. the only thing I did different this week was giving an extra litre of water when feeding the plants DAY 71 - Nutes PH - 5.92 Solution Temp - 18.5 PPM-1760 Watering Volume per plant - 5L DAY 76 - Water PH - 6.05 Solution Temp - 17 PPM-571 Watering Volume per plant - 5L

No problems to report this week. Healthy growing plants. DAY 78 PH - 5.9 Solution Temp - 16.5 PPM-1800 Watering Volume per plant - 5L DAY 82 - Water PH - 5.95 Solution Temp - 15.5 PPM-603 Watering Volume per plant - 5L

I starting to see a bit of light bleaching this week. This week I did a bit of defoliation but nothing too crazy, next week I will do the last defoliation. DAY 87 PH - 5.95 Solution Temp - 15 PPM-1900 Watering Volume per plant - 5L DAY 90 - Water PH - 5.95 Solution Temp - 15 PPM-560 Watering Volume per plant - 5L

Light bleaching got a bit worse, but nothing too serious This week I did a big session of defoliation, you can see on day 92 that the plants were a bit "naked". I noticed that the humidity was a bit high this week, around 60%, to mitigate that I decided to give only 4L when watering instead of 5L, I also bought another fan that I will install next week. One of the major mistakes that I did this week was giving the wrong nutrients when feeding. Instead of giving week 4 nutrients, I gave week 5 nutrients, no visible problems but I think the size of the buds could be a bit bigger, I don't know if the correct nutrients would have change the size, I would never know. Another mistake that I did this week was the fact that the temperature of the water was too low, 14 degrees is very low and can cause problems, I didn't see any visible problems, but I think the size of the buds may have been affected. DAY 92 PH - 5.94 Solution Temp - 14 PPM-1925 Watering Volume per plant - 4L DAY 96 - Water PH - 6 Solution Temp - 14 PPM-640 Watering Volume per plant - 4L

I still have problems with high levels of humidity, usually around 65% during the night and 55% during the day, I ended up removing more leaves to try to reduce the amount of humidity in the air. I can see that the buds grew since last week, I was expecting the buds to be a bit bigger this week, but I'm happy with the current size, but I'm happy with the amount of trichomes present. DAY 96 PH - 5.93 Solution Temp - 19 PPM-2000 Watering Volume per plant - 4L DAY 103 - Water PH - 6 Solution Temp - 18 PPM-690 Watering Volume per plant - 4L

I still have problems with high levels of humidity, but I discovered that if I open the window of the room to let fresh air in I can reduce the humidity in the air. This week I introduced molasses in the water, I used 1 tablespoon for every 4L of water. From now on I will only use nutes and molasses. The buds are not huge, but they are full of trichomes. I saw a bit of nutrient burn on a few leaves, nothing to worry about, I guess PPM around 2000 is a bit too much for this strain. DAY 108 PH - 6.01 Solution Temp - 17.3 PPM-2150 Watering Volume per plant - 4L DAY 112 - Molasses PH - 6 Solution Temp - 19 PPM-610 Watering Volume per plant - 4L

I'm starting to see top leaves starting to change colour on the plant to the right, I hope the progression of this problem does not kill the plant. DAY 116 PH - 6 Solution Temp - 17.5 PPM-1705 Watering Volume per plant - 4L DAY 119 - Molasses PH - 6.08 Solution Temp - 19.7 PPM-573 Watering Volume per plant - 4L

Change in colour on the plant to the right is getting worse. DAY 121 PH - 6.05 Solution Temp - 18.5 PPM-1740 Watering Volume per plant - 4L DAY 124 - Molasses PH - 5.96 Solution Temp - 17 PPM-587 Watering Volume per plant - 4L

Change in colour on the plant to the right is getting worse, I only have one week left until the end of the grow, hopefully the plant will survive until the end. From now until the end of the grow I will remove one hour of light every day, until the last 3 days of full darkness. DAY 128 PH - 6.05 Solution Temp - 17 PPM-1900 Watering Volume per plant - 4L DAY 131 - Molasses PH - 5.95 Solution Temp - 16.1 PPM-475 Watering Volume per plant - 4L

Last week of flower, I flushed during the last 4 days, I didn't do big flushes I simply water the plants with plain water, last 3 days of complete darkness. I think that next time I will complete the flush and then give 3 days of complete darkness, the fact that the plant is not receiving light makes flushing harder because the plant drinks less water. During the last 3 days, the humidity was always greater than 50% but the plants didn't seem affected. Before I started the flush the pant was only receiving 8h of light. I'm currently drying the plants, the temperature fluctuates between 17 and 19 degrees, I start with 65% humidity and I reduce 1% of humidity every day. I Do a 14 day dry DAY 134 PH - 6.02 Solution Temp - 16.9 PPM-1955 Watering Volume per plant - 4L DAY 136 - Molasses PH - 5.92 Solution Temp - 15.2 PPM-300 Watering Volume per plant - 4L

I used different techniques during this harvest, from LST to supper cropping, and the plants reacted like it was nothing. The only thing I would do differently next time is the flushing and the time of harvest, instead of chopping down the plants at day 70 and flushing from day 66 to day 70, next time I will chop the plants down on day 75 and flush from day 70 to 75
