Lemon Shining Silver Haze coco 80x80x180

stuffyloir :) Days 10-16 October -Day 1 10/10/25 9:40 all 3 jiffys have been placed in pots of about 1-1.5l [70% canna coco professional plus (pre-buffered) + 30% perlite], leaving them about 1cm above the soil to let the roots breathe; PPFD about 250-300 (in the shade); watered with pH: 5.9 and EC: 0.15 (supermarket H2O); Every now and then I'm turning the pots 90° to help the stem develop well. -Day 2 11/10/25 Today I moved them under the light and took off the cup for a few hours, so they can start getting used to the environment. PPFD: 250/270 H2O: about 30ml per plant -Day 3 12/10/25 About 30-40 ml of water at pH: 6 On the leaves when the plant is under the cup, droplets of water form on the tips of the leaves, probably due to guttation, the plant can't handle all the water, and it expels it from the tips. This caused a small burn on one Cherry leaf (see photo), maybe due to lens effect. -Day 4 13/10/25 About 50ml water at pH: 5.9 -Day 5 14/10/25 This morning I watered the plants with about 50ml of water and NUTRIENTS at 70% of the recommended values from Terra Aquatica (0.3ml/l micro, grow, bloom), final EC 0.45 and pH: 5.9. Alesha seems to have stalled for a few days, maybe some issue with the transplant (next time I'll put the root directly in coco and perlite), let's see if the fertilizers improve the situation. I'm currently waiting to cut the other plants in flowering to set the VPD properly inside the growbox, for now I'm using cut and perforated bottles to keep the humidity high. Bobby and Cherry have started to develop the second set of leaves after the cotyledons. -Day 6 15/10/25 Today I gave about 25ml of H2O with nutrients (70%), I stopped moistening the bottles that act as a dome for the plants. Slowly they are getting used to a higher VPD. The first leaves of Alisha are growing, even though they have a strange color. -Day 7 16/10/25 About 25-40ml of H2O with nutrients, still the same concentration. The color of the plants is a nice green, they look healthy, a bit of stress from high VPD (there are still OG Kush autos in flowering in the growbox).

stuffyloir :) Days 17-23 October -Day 8 17/10/25 During the 1st week, B and C have grown a lot, especially B. The third set of serrated leaves is on the way. While A got stuck for a few days (maybe too much humidity?), it's now growing, has some curling on the leaves, probably due to the VPD fluctuation between the growbox and under the bottle. There are still the two OG Kush autos, I hope they are ready next week so I can set up the growbox and transplant the Trio into 20L fabric pots. -Day 9 18/10/25 I gave about 50ml of water with nutrients, 0.6ml/l (micro, grow, bloom). -Day 10 19/10/25 I soaked the 3 pots in water with nutrients 0.6ml/l for about 20 minutes to ensure the bottom of the pots got well-moistened to stimulate the roots. -Day 11 20/10/25 I added coco and perlite to the pots to cover the jiffy well. Roots were coming out on the surface. I didn't water because it was still moist; yesterday I let the pots soak, and today the moisture was well distributed throughout the coco, even to the surface. It seems like a great thing. -Day 12 21/10/25 This morning I lowered the light power to 75% because the humidity was dropping too much (the radiators are on and drying the air, in the growbox it was dropping to 40%). Now I've created a box with two plastic containers, one on top of the other but separated, with a fan pointed so that there is air circulation. This way, the internal humidity has stabilized at 60%, and the temperature around 22°C (leaf temp: -1.5°C), so VPD ≃ 0.8kPa. -Day 13 22/10/25 Nothing particular to add, they are growing and look healthy. As soon as possible, I'll transplant into 20L fabric pots. -Day 14 23/10/25 Since the humidity in the growbox is still too low, and with the lid on top, it creates air stagnation. I opted to create a temporary solution to increase the humidity around the seedlings using an ultrasonic diffuser and a bottle.

stuffyloir :) Days 24-30 October -Day 15 24/10/25 I gave about 20ml of water each. Tomorrow I'll water properly. I raised the lamp by about 10cm. -Day 16 25/10/25 First signs of "hunger," cotyledons a bit faded. Today I watered 300ml per plant with a concentration of 1/1/1 ml/l of micro-grow-bloom pH in: 5.9 EC in: 1.17 Alesha pH out: 5.9 EC out: 0.78 runoff: 100ml Bobby pH out: 5.9 EC out: 0.83 runoff: 100ml Cherry pH out: 5.9 EC out: 0.80 runoff: 100ml All three seedlings have reached the bottom of the pot with their roots (see photo), tomorrow or in the next few days I'll transplant them into 20l fabric pots. They have some signs of stress, likely high VPD, light a bit too strong (tight internodes), and irregular watering these days (I gave too much water last week and it took a while for the coco to dry out). Advice for the future: don't put flowering (auto) plants and seedlings in the same growbox, they require completely different temperature and humidity, so unnecessary stress for the plants. -Day 17 26/10/25 Today I closed one air intake near the seedlings and opened another one further away. There was too much air moving nearby, and the leaves were transpiring too much. Now they are all back to horizontal and perfect. No photos today, I forgot :) -Day 18 27/10/25 The plants are doing well, Bobby has some signs of deficiency from the past few days, but is growing like the others. The temperature remains between 19 and 22 degrees, maybe a bit low at this early stage, but if I turn on the heating the air gets too dry. Question: does soil with temperatures around 20 dry more slowly compared to 24-27, so less watering = fewer nutrients? -Day 19 28/10/25 The plants are growing, tonight the soil is almost dry enough to water, but I’ll wait until tomorrow so I can take advantage and transplant all 3 into 20l fabric pots. Today I used a spray bottle to mist the leaves with a solution of 300ml distilled H2O and 0.5ml of T.A. micro. I diluted until I reached the recommended EC of 0.6mS. pH: 6.0 Morning-afternoon-evening. -Day 20 29/10/25 Today I finally cleared the growbox, so a thorough cleaning (fans, dust filter, extractor, growbox, lamp). I transplanted the seedlings into their final 20l fabric pots, I waited for the coco to dry a bit more so the roots stay compact. All three have a beautiful root system (see photo). After filling the 20l pot, I dug a hole in the center and checked that the pot they are in now fit. Then I watered the hole with 500ml of tap H2O with fertilizers (1.8ml/l grow, 1.2ml/l micro, 0.6ml/l bloom), placed the seedling in the hole, and covered it with more coco and perlite. After leveling the soil in the pot, I watered around the plant with about 150ml of the same H2O with the previous fertilizers. PPFD: about 280 Temperature: 20° (low, extractor too powerful) Humidity: 57-60% (great) Currently, my only concern is the temperature: The extractor, even at minimum speed, pulls away a lot of air, which doesn’t allow the air to warm up enough from the light. To solve this, I should buy a socket with a dimmer that regulates the voltage and thus the speed. -Day 21 30/10/25 No photos today, I forgot. The plants are doing well, they seem not to have suffered from the transplant.

stuffyloir :) Days 31-6 November -Day 22 31/10/25 The plants are doing well, they've slowed down a bit in growth after the transplant, probably using energy to fill the pot with roots. -Day 23 01/11/25 I lowered the PPFD to 200. After the transplant and probably due to a slightly low temperature, the leaves were a bit droopy. Let's see how they react. -Day 24 02/11/25 Today the pot was dry enough to do LST. The goal is to give the new branches time to grow all to the same height, then arrange them with a SCROG net. I used safety pins to anchor the thin wire (used as "rope") to the pot and the rubber-coated wire (used as a ring attached to the plant). First, I decided which way to bend the plant, then I anchored the base of the plant so that it pulled in the opposite direction of where I wanted to bend it. Then I placed the safety pin on the side where the plant will be directed, tied the wire, and slowly with my fingers bent the main branch at the height of the 3rd node, going step by step, bending the plant more and more until the tip was at the same height as the 3rd node. (see photo) This procedure is best done just before watering, so the plant is as flexible as possible and doesn't break. After finishing LST, I watered with T.A. Tripart: Micro: 1.2 ml/l Grow: 1.8 ml/l Bloom: 0.6 ml/l pH: 5.8 EC: 1.36 H2O: 1l/plant, total 3l (next week when the roots are nicely grown, I will increase the water volume until runoff, to wash away excess salts) -Day 25-27 03/11/25 - 05/11/25 During these days the plants have grown, they're a bit slow I imagine due to the low temperature (19-21°C). But despite the speed, they seem healthy, the leaves are a nice green and the first results of the LST are starting to show. Every two days I check and adjust leaves and branches so as not to cover the lower parts of the plant. 06/11/25 I brought it to about 260-280 PPFD by raising the lamp a bit and moving it from 25% to 50%. I noticed that the plants grew faster during the period when the pot was drying out. When the first 2 cm dried, I watered with about 3L of water per plant. It's the first substantial watering in the 20L pots, pH at 5.7-5.9 (I had to create two solutions and the second had a slightly lower pH) EC in: 1.44 Cherry Run off: 400ml pH out: 5.9 EC: 0.86 Bobby Run off: 1l (too much, initially nothing came out, then all of a sudden) pH out: 5.7 EC out: 0.73 Alesha Run off: 450ml pH out: 5.8 EC out: 0.93

stuffyloir :) Days 07-13 November -Day 25 07/11/25 The temperature issue hasn't been resolved yet, and it's really showing in the slightly slowed growth. No photos today. -Day 26 08/11/25 The side branches are stretching out, the temperature stays low below 22 degrees when the heating comes on, I need to find a solution, I was thinking of an electric blanket laid under the pots. -Day 27 09/11/25 Today I'm adjusting the plants by lowering the top and uncovering the covered branches. I've raised it to 290 PPFD and brought the light closer, dimming it to 25% to keep the leaf temperature higher. Let's see if it works. -Day 30 12/11/25 It seems that 290 PPFD is too much, I've noticed some burn on the tips (it could be a magnesium deficiency, so the plant can't use the light energy). Today I adjusted the branches and leaves. For now, I'm bending them over each other without cutting them.

stuffyloir :) Days 14-20 November Day 33 15/11/25 I've been busy these days and I let the coco dry out a bit too much. Today I watered with: 1.2ml/l micro 1.2ml/l grow (I lowered it because there were starting to be signs of toxicity) 0.6ml/l bloom pH in: 5.8 EC in: 1.36 Bobby: 4.5l in runoff: 800ml pH out: 5.3 --- the result of letting the coco dry out too much EC out: 1.16 Alesha 4.5l in runoff: 700ml pH out: 5.5 --- same EC out: 1.30 --- almost like in (possible blockage/salt buildup?) Cherry 4.3l in runoff: 120ml -- little pH out: 5.8 EC out: 1.03 -Day 34 16/11/25 Since yesterday the pH was too low because I let it dry out too much, I want to start keeping the coco always moist, today I watered again to try to fix the pH 1.2ml/l micro 1.2ml/l grow 0.6ml/l bloom pH in: 5.8 EC in: 1.32 Bobby 1.8l in runoff: 700ml pH out: 6.15 -- ? EC out: 1.23 Alesha 1.8l in runoff: 900ml pH out: 6.1 EC out: 1.23 Cherry 1.5l in runoff 200ml pH out: 6.4 -- need to keep an eye on this EC out: 1.32 -- same as EC in -Day 38 20/11/25 I increased the PPFD from 290 to 340 I did LST by bending the branches to open up the center well and allow light to reach the smaller and lower new nodes. In the meantime, I also cleaned up a bit by removing some leaves. Today I watered with: -1.2 micro ml/l -1.2 grow ml/l -0.6 bloom ml/l EC in: 1.41 pH in: 5.8 Bobby: 2.5l runoff 1l EC out: 1.00 pH out: 5.9 Alesha 2.5l runoff: 1l EC out: 1.12 pH out: 5.9 Cherry 2.5l runoff 1l EC out: 1.19 pH out: 5.9

stuffyloir -Day 40 22/11/25 Today I watered with the same doses as last time ec in: 1.53 ph in: 5.8 Bobby 2.5l runoff: 800 ml ec out: 1.14 ph out: 6.0 Cherry 2.5l runoff: 1l ec out: 1.30 ph out: 6.1 Alesha 2.5l runoff: 900ml ec out: 1.20 ph out: 5.9 Today while I was adjusting the main branch of Cherry and Alesha, they broke but stayed attached. I put some tape to keep them straight; I'm sure they'll fix themselves, and in the meantime, the lower branches have time to catch up. I also found some light spots with a brown center (see photo) on one leaf; I still haven't figured out the reason. In general, the plants are healthy, growing quite a bit; there are now about 15 branches, almost all at the same height. Soon I'll put up the SCROG net to cover the entire surface of the grow box 80x80cm. In hindsight, I should have put it up earlier.
