The little plant seems to stretch a bit. I'm going to slowly lower the light daily. Added a bit more of soil before watering on the second day after sprouting to contain the problem.
Day 5. I lowered the lamp to 20 cm distance from the plant. She stopped stretching, now I will let her grow until she reaches 15 cm distance from the lamp, then I will keep that distance for the vegetative stage.
Day 9, she's working on her third pair of leaves. Everything looks fine for now.
Day 11, the soil is taking a bit longer to dry out, I probably gave her too much water. I will water less next time. Luckily she still looks fine.
Day 15, start of the third week! She is now growing something between 1-2 cm per day. Next watering I'll start to feed her a small amount of organic grow nutrient.
Day 16, the top two pairs of leaves have started to curl in a claw-like shape. I personally don't think is overwatering, because I lowered the amount of water last time and even the previous time she didn't show any symptom. Could be I maybe waited too long to water her this time? The first couple of inches of soil looked still moist this morning, so I did non water her yet, but now that the light has turn off I tried again the "finger test" and noticed is a bit more dry (I'm usually watering twice per week). I will water her tomorrow morning and we'll see. Measuring her distance from the lamp twice a day, so I don't think is light burn (CFL agro 125w at 15cm of distance). Can maybe be wind burn instead? Today I changed the fan speed to a higher level, just to see if it was drying the soil a bit quicker. I re-adjusted the fan speed at the previous level just in case, but is just a small fan hanging in the top of the tent, is not so close to the plant. Again, we'll see. If you have any idea/suggestion, please leave a comment.
Day 17, leaves were back to normal shape before watering. Probably was the wind. First feed today, 0.4 ml/l of Biobizz Grow.
Day 18, first LST! I hope I did a good job, this was my very first time. Let's see how she is going to react.
Night update: the main stem went back up again in a few hours, it seems she's reacting good to the training. I tuck back the fan leaf that was covering the little side stems.
Day 19, the soil looked dry again and I watered with a bit more of nutrient (0.6 ml/l this time) but I probably gave her too much water or maybe too soon, because the new leaves look a bit droopy. I will wait a few more days to water her again. For the rest she is growing as usual. The new growth looks a bit twisted today, I will keep an eye on that.
Day 20, leaves are now back to normal. She is growing as usual.
Day 21, I noticed what it seemed like light stress on the tips of the new growth (yellowing). I put the lamp a bit further away, 20 cm now (was 13 cm this morning), we'll see if this is going to improve the situation. Probably it's because the Cultilite CFL is a lot more powerful than common CFLs.
Day 22, second LST bending of the main stem. She is enveloping nice side branches.
Day 23, feeding day: 0,8 ml/l of bio-grow.
Day 25, third LST bending on the main stem. Side branches are stretching a lot.
Day 26, The yellowing of the tips in the new growth is slowly getting worse, first was only in the very upper growth, now a couple of side branches have started to show the same symptom. I'm not sure anymore is light stress. I put the lamp a bit further away just in case.
Day 27, Thanks guys for your answers. Today I watered with just plain PHed water at 6.5, I had a little runoff and I took the occasion to check it's ph as well, which was 6.0. I'm going to try the suggested water-water-feed schedule, reducing the amount of nutrient for the next feed back to 0.4.
Noticed some little pistils and calyxes as well today. Can't wait to watch her flower.
I'm experiencing some yellowing of the tips in the upper/newer growth. Light stress? Nutrient burn? Deficiency? Ph related issue? Should I do a flush with plain PHed water and check the ph of the runoff? I will do some more pictures tonight with the grow light off.
You have a little nutrient burn. The dark green glossy leaves with the discoloration on the tips says that it is getting a little too much nitrogen. In soil it is best to feed every third watering. So water, water, feed, repeat. This should keep the plant pretty happy. The burn is minor so nothing to really worry about at this point. Good luck with the rest of your grow!
Day 29, LST adjustment day! Fourth bend of the main stem. Some of the side branches seems to have got taller, tomorrow I will adjust them accordingly.
Day 30, some canopy adjustment with LST.
Day 31, watered with just plain PHed water (6.5). Runoff ph 6.0
Day 33, canopy adjustment with LST.
Day 34, another bend of the main stem.
Day 35, watered with just plain PHed water. She is showing some nice pre-flowers.
Day 36, started to run a dehumidifier to keep the rh around 50%.
Day 37, canopy adjustment.
Day 38, she grew 3 cm overnight! I did another bend of the main stem. The soil was really dry, she is starting to drink more than usual. I also noticed some yellowing in the lower leaves and some shades of red on the petioles, so I gave her a bit of nutes again with the watering (1/5 of the recommended dose, let's see if it's enough). No need to ph the water today, it was already at 7.0 after adding nutes.
Day 39, canopy adjustment. And... I supercropped one stem by mistake lol. I'll leave it like this, I want to see if it recovers and if it's going to take much longer than the others which I have just LSTed.
Night update: the supercropped stem made it like the others! Now I think the canopy is pretty fine, I'll try to keep it flat and even until the end of the stretch. She is sturdy and growing like there is no tomorrow.
Day 41, watered with just plain PHed water (between 6.5 and 7.0). Runoff between 6.0 and 6.5.
Day 43, start of the week! Buds are developing, but the lower leaves are still showing a slighlty deficency. PH of the soil is in range, so I'm going to give her a bit more of nutes in the next watering (probably tomorrow, the soil was already a bit dry today).
Day 44, water and feeding.
Day 47, watered with plain phed water (7.0). Runoff 6.5
Day 49, buds are fattening and frosting. It seems she doesn't need nitrogen anymore (and I think I gave too much of it again), so next watering I will not add nutes at all, and the one after that I'm just going to give her bloom nutes.
Day 50, watered with just plain PHed water 7.0, runoff 6.5
Day 53, watered without nutes again. Ph between 6.5 and 7.0, runoff almost the same.
Day 56, watered with just plain PHed water at 6.5, runoff had the same ph.
Day 57, buds are starting to mature, tomorrow I will start to check the trichomes, but probably It's going to take at least 2-3 more weeks.
Day 59, watered with a bit of Bloom nute. Ph around 7, runoff a little more than 6.5
Day 62, watered with just plain PHed water (6.5, runoff almost the same)
Day 64, I spotted a couple of leaf miners' tunnels, but just one adult fly. I can't see any larvae anymore, not even with the jewel loupe. I hope it was just a couple of them and they stopped laying eggs. I'll try to low the humidity a bit more to make the environment less ideal for them.
Day 65, watered with a bit of bloom nutes. Spotted another damaged leaf and another fly, so I hanged a sticky trap as well, hoping those bitches are going to leave my poor plant alone soon.
Day 67, spotted and killed the adult fly. No larvae spotted, I'm not sure anymore that this was a leaf miner, could have been a thrip as well looking closer to the damaged leaves.
I've cleaned the equipment, the box and removed those eaten leaves.
Day 68, watered with plain PHed water 6.5, runoff 6.0
No more damage on the leaves spotted.
I spotted leaf miners' damage on a couple of leaves and an adult fly. What can I do to prevent them to spread and get rid of them at this stage of flowering? For now I'm trying to low the humidity a bit more to make the environment less ideal for them.
Day 71, watered with nutes (ph between 6.5 and 7, runoff around 6.0). She is still packing new flowers and there are still a lot of clear trichomes.
Day 74, watered with plain PHed water.
Day 77, watered again with plain PHed water. I noticed some weird little browinish/beige dots near the veins of some leaves, mostly the upper/center ones, those exposed to the light. I checked for bugs everywhere, even with the jewel loupe, and I haven't see one. What can it be? Maybe heat/light stress? Every week there is something new lol

I would not worry much first :-) your plant looks great, and is already in full bloom production :-) The site can have many factors, but we should all know about the grow
Day 78, the trichomes are mostly cloudy and milky, but the plant is still putting on new flowers almost daily. Two more weeks maybe? I'm not sure about starting the flush yet or wait a bit more.
Day 80, watered with a small amount of nutes. She is still putting new flowers, but she's also foxtailing a bit. I put the lamp 3 cm further away and I'm trying to lower the temperature with ac. From next watering I'll start the flush, probably by the end of next week I'm going to harvest. For now I just took a small sample before watering, I'm letting it dry in a cardboard box to see how is the thc level now.
Day 84, watered with plain phed water. She is starting to drink less water, probably because she is not producing new flowers anymore. I will let them mature some more days and then I'll chop.
I removed the fan leaves the night before the harvest and I left it in the dark for about 14 hours before the chop. I hang the plant whole with the sugar leaves to dry it as slow as possible.
I'm trying to lower the temperatures as much as I can with ac (now they are between 21-25 °C) and humidity around 50%.
I'll update with more info after drying and curing. For now I can tell from the sample I took during week 12 that this smokes lovely, it's totally covered in resin and the high is very strong (balanced mind/body) and lasts for hours. After 7 days of drying it smells really nice, like lemongrass with a bit of mint and pine. Tastes a bit like hashish with some herbal flavour as well.
After 3+ weeks of curing it started to smell strongly nutty (yummy).
Dry weight: 24 grams. Now I'm freezing the trim to make some kief.
