Sensi #741 by TOTEM

Welcome back everybody! I’ve got some good news. I’m so excited because Sensi Seeds asked me to test their new strains. The project is called Sensi Seeds Research, and they basically breeded some of their best strains with other ones, both new and old, and planned to release some of them in the future. They still don’t have a name, and they come just with a number and their lineage description. Our mission is to test them, and then find a suitable and interesting name for each. So, there are many autos, some high CBD feminized strains, and 4 high THC ones. In the end I asked to send me these 4, which are: Sensi #11: Blueberry x Afghani x Silver Haze Sensi #32: Silver Haze x Fire OG (OMGGGGGGG) Sensi #140: Chocolope x Hindu Kush Sensi #741: Sour Diesel x Afghani Sooooo, I planned a 4 plants grow in 9L Air Pots. I’ll mainline them in Nebula style in order to get 8 big colas each, and I think we’re gonna laugh here because some of them are more sativa than others, so just think about their stretch when flowering starts. As you may know the Silver Haze is favorite strain, so my hype for the Silver Haze x Fire OG is endless!!! SETTING It will be a soil grow. I’ll start with 1L Air Pots, then transplant to 3L ones, and finally to the 9L ones. Biobizz Light Mix for the germination and Canna Bio Terra Plus for the rest of the grow. For the germination I added a layer of Xtreme Gardening Mykos 1cm under the seeds, and but will use Mykos in every transplant too. I’ll be using Biomagno nutrients line, starting from 1/4 of strength from day 14 to day 28 (from sprout), increasing to 1/3 after day 28, and possibly 1/2 on very hungry plants. But I’ll go very soft because I don’t strains. Less is better, so I’ll always be able to add more if needed. I’ll try to water with osmotic water or rainwater only in order to avoid killing mycorrhizae and other organisms. I still have to figure out if I’ll use a pH meter and correct pH each time. I’d like to try without. I’ll grow in both veg and flower with my 600W Cree CXB3590 COB panel. I’ll use the same tent I’ve always used: Mammoth Pro 100, 1x1x2m (3.3x3.3x6.6ft). LET’S GO!!!!! Day 1 (April 10, 2019): Planted the seed directly into the soil. Day 6 (April 15, 2019): Sprout day! It’s been a little cold inside the grow box. Day 7 (April 16, 2019): Switched on the COB panel. Double-sun power!!

Not much to say for the moment! At the end of the week I discovered the timer was keeping the light 24/7 on! 😱

Sensi #741 is the most developed in terms of leaves and nodes, but for the moment she’s quite short compared to #32 and #140. Day 15 (April 24, 2019): I decreased light distance from 130 to 100cm. Some leaves are curled up because RH is low (around 40%) while temps are quite high (around 30C). Day 18 (April 27, 2019): First feed @ 0.5ml/L.

This is a very interesting week! After mainlining, I transplanted the lady into a 3L AirPot, adding 3 spoons of Mykos by Xtreme Gardening, 45g of BioMagno Algae and 5g of BioMagno Neem Flour. I uploaded a time-lapse video that shows the process. Then I fed her with the nutes you see above this comment, in 1L of water (actually, 750ml would be better). I hope you liked this week content! Day 28 (May 7, 2019): 0.5L of tap water with Activator @ 0.5ml/L and Rizostimo @ 1ml/L.

Oh shit! I think she's slowly fixing this calcium deficiency since I'm now always using tap water, but many leaves are affected and the look of the plant is terrible. By the way she's got the fastest growth rate: maybe a little too fast compared to her sisters. Since I'm aiming to have the same shape and final height for everyone, this could be a problem in the next weeks. By the way, next week I'll top to the new 2nd node and over the 3rd, in order to get the final 8 colas structure, and will integrate with some Biomassa (CalMag) @ 0.4 EC for 1/2 times. Day 34 (May 13, 2019): 0,5ml/L of Crescita, 1ml/L of Activator and Rizostimo in 750ml of tap water.

Whoa. What a fast growth pace for this strain. she definitely loved mainlining and I think that may be Sour D genes! I think I need to give more nutrients because she looks like too much light green. In the meantime, with some Biomassa (CalMag) @ 1ml/L, now she feels so much better and I can’t see CalMag deficiencies anymore. And she was the one with more CalMag problems. But even if she’s the biggest and most developed, I can barely see roots coming out from the bottom. She’s the opposite of the #11. I don’t know why! And that’s probably why she takes so long to suck all the water, compared to the others (#32 especially). Unfortunately this week I was busy and had to take the photos with my phone. Day 36 (May 15, 2019): Decreased light distance from 100cm to 70cm. Then 2nd node removed and topped over the 3rd one. Day 41 (May 20, 2019): Feed with Crescita and Activator: 0.5ml/L, Rizostimo and BioMassa: 1ml/L. ~750ml of water each.

This is the last (hard) training week! Next week I’ll transplant her into her final 9L pot, then wait a little, and then switch to 12/12. Day 43 (May 22, 2019): I bent down every branch because her growth rate is impressively fast compared to her sisters. Day 43 (May 22, 2019): Feed following the linked schedule. I added more roots stimulator because I’d like to create a better root base before the final transplant into the 9L AirPot. Day 49 (May 28, 2019): Heavy defoliation keeping only the last nodes, then fed following the same previous schedule.

Earlier this week I transplanted her into the 9L AirPot. Now that I don't have to train her anymore, I just need to wait until she's 40-50cm tall, and then I can switch to 12/12. In this project I'm aiming at 8 long colas for each plant.

She's quite short! Do you remember her in the first weeks? She was the ones running faster with long branches too. Now yes, she's got long horizontal branches, but she's growing slowly. She's the shortest of the group, and I have to be careful giving her nutes because she may not tolerate them. If you remember, some weeks ago, giving the same quantity of nutes of the others, I overfed her and all the tips of the leaves got yellow and white. Next will I'll try with a low dosage of base veg nutes. I'll switch to 12/12 as soon as Sensi #11 reaches 50cm, and I'm a little worried this #741 could not reach even 40cm by that day (which is the minimum height in order to get big long colas with mainlining). Fingers crossed!!!

Slooooow growth like always this week. Her leaves are soon small, but it's fun because they're basically very sativish leaves in a very small plant. Not something you see everyday. I think now she can handle nutes more easily too. I only had to wait for some more leaves development before adding nutes some weeks ago. I'm still forwarding by a constant trial and error with all of them by the way. This week I added nutes back, but just once, even because she doesn't tolerate them so much. Last week I had a big gnats infestation, but Mosquito Dunks worked like a charm. No one left! Niiiice!

This is her last veg week. Just a heavy defoliation before the switch to 12/12 that I'll make on the first day of week 12. At the beginning of the week applied some foliar B-52 and Nirvana @ 0.5ml/L, then some more after the big defoliation I did at the end of the week, this time inside the watering solution, @ 2ml/L. She finally grew up a little bit, and I'm not saying she reached her sister Sensi #11, but she definitely gained some real height. I called her "Sensi Zapdos" haha!

Flowering has started! How can't you love this plant (and pheno)? She's short, but has sativa leaves always pointing to the sky. This means she's always happy! I hope she will gift me with a wonderful smoke. I'm even thinking about taking some clones on around week 3, when I'll do the last big defoliation. She's quite compact, but develops many lower colas that come out from literally anywhere. This is amazing because I'm sure she will be FULL of flowers very soon. Wow I can't wait to see what happens on her! She also started showing the first primitive form of flowers at the end of this first week. What a satisfaction!!! This week I watered twice: the first time with flowering nutes by BioMagno @ 1ml/L, the second time with just B-52 and Nirvana from Advanced Nutrients. Just some experiments, so I can see how they react alternating different (but always good) food. I can tell you every one of them reacts to that B-52 + Nirvana cocktail by raising their leaves to the sky like they are praying, so yes, it's actually a very powerful cocktail!!

Took a while for this update because last week I lost my camera's battery charger. Finally we can see the first flowers! Everything good. I love how she's always praying to the sky, which is sign she's always happy. I called her "Zapdos", like the legendary Pokémon, because she has the same pattern with her leaves. She suffered in the first weeks because she apparently didn't need many nutes, but now she's loving them. Basically I'm alternating one time feed and one time just water. Always correcting pH to 6.5 before pouring the solution into the pot. I also spotted some trichomes around the flowers already. She seems to be so fast! I'll do a big defoliation by the end of this week.

There we go! I love weeks 3. They always remind me of the ScrOGs I did in the past... the first flowers, the end of the stretch period... plants finally pushing all the energy to their flowers: yeah baby!!!! Let's see what I can tell about "Zapdos". At the beginning of this week I did the last big defoliation. Many lower flowers were covered by fan leaves, so I removed them. I also got rid of some lower bud sites that would have never received enough light if I kept them. As you can see, everything is clearer now. Since last week she's gained 1cm only: this means her stretch has come to an end, and she can now put all her energies into flowers development. I'm alternating Biomassa and Florastimo, one week each. Biomassa has CalMag inside, Florastimo has some other good stuff like vitamins, amino acids and algae. Have you seen how many fungus gnats I've trapped? Fucking fuckers. Mosquito Dunks didn't work properly: it's better to use it by spraying it on every AirPot's hole, instead of using it inside the water solution.

Oops. Burned tips. Her leaves have been darker than her sisters' for long now, so I knew she didn’t need much food. But I definitely didn't expect her tips to get burned so easily. This is the reason why this week I gave only water. I started this journey with a personal favorite: Sensi #32. But this soon changed when I saw Sensi #741's "Zapdos structure". I literally fell in love for her. Her flowers smell like..... Peach! Red fruits! Tropical! Passion fruit! OH MY GOD. The only unknown is the effect. The point is that I can't lose this pheno. This is why, though we are on week 4, this week I took 3 clones from her. It's the second time I try doing this, and the first time I failed because they developed bud rot. It's true that clones are usually taken in veg, but I read this can be made in flowering too. If it works, new branches should come out from the flower, and will be horrible looking at first. But let's try this!! She's developing 8 big and dense colas. I expect them to be really big in the end, but I expect the same for the lower and smaller ones. As you can see those ones are frosty too. Wow, how can't you love this girl?

Oh my. Last week I was talking about N deficiency, but in reality she was perfect! The real big problem was my pH pen, that was broken, and when I thought I was giving a pH 6.5 solution to my plants, in reality the pH was a lot lower than that (maybe pH 4). That's why her leaves all started getting yellow! Runoff PPMs right now, after the feed, are 3100 lol. I decided not to flush her, but I'll give just water until that value decreases a little. Her flowers are bigger, and smell more and more, day after day, of fruit. I LOVE HER. But what a pity for those burned tips! I also have some updates on the clones. One of them created 1 single root, haha, but YAY, I'm so happy about it. That clone was fast! The other two are still there, but my fingers are crossed. There's a video of the clone after all the photos.

Week 7, big flowers and another big defoliation in order to get even bigger colas. You know how long it takes to clean up all those lower popcorn buds, right? Because I do, and this month I’ll not have any time to do that. So... I removed them. All of them. And kept just the bigger ones. As you can see, this lady is almost totally naked right now. Aw yeah! Her 8 main colas are already quite big, and this defoliation should make her focus only on them. One week left? Maybe two? I don’t think a lot more. I’ll be start checking trichomes very soon, and you too with the high quality photos I’m uploading. Stay tuned!

Argh... I hate those very light green leaves. Almost yellow. No, I don't like how she came to the final phase of this cycle. Yes, I had problems with my pH meter some weeks ago, but I've been giving everything right after that. It seems like she has some Fe deficiency, which causes the yellowing of leaves. Maybe she just needed more nutes... I don't know, but fuck. At the beginning of this week I fed for the last time after a water-only week, then on last day of the week I started flushing. I flushed with 30L of tap water (pH corrected to 6.5), that is around 3x times the capacity of the pot (9L). I got a runoff consisting in pH 7 and 525PPMs. I think this deficiency made her buds not to grow properly, and in fact at the moment they're not that big. Maybe they will fatten a little in the next two weeks, but I'm not that sure these leaves color will allow that. I also posted the clones photos. Two of them have rooted and they're looking good. They're kept under a 24/0 cheap light bulb (I think it's a 9W one). I'm alternating a foliar rooting solution with just water, being careful to never allow leaves to get too dry. I'll transplant them into soil as soon as they root a little more. See you next week!

FLUSH FLUSH FLUSH! I still can't figure out what happened here. N deficiency? Light burn? Wanted more nutes? It was too hot? That leaves are really embarrassing, and it seems like her buds are not growing anymore because she's lacking some food. At this time she's almost done, and her trichomes are all milky with some already amber. Almost time to harvest. Sneak peek time! Some days ago I tried a small sample. What can I say? Taking those clones was one of the best decisions of my life. Amazing high, like 70% on the head and 30% on the body. Will describe it better in my final review of course!

Thank you Sensi Seeds for this strain. The best of the best like always. Can't wait to grow all your other strains!
