Seed germinated after 3 days, the seedling looks a bit stretched but healthy and vigorous. Just a few water to keep the soil moist and plastic bottle+nebulizer to increase HR. Let's see what happens :)

The stem is pretty long (4-5 cm). Is it normal for this strain? Thanks, M.

Move her closer to the light a bit. When you transplant you can bury her to your liking.👍

Transplanted in soil with perlite and half teaspoon of mycorrhizae. I proceeded with irrigation and roots stimulator in day 13. The lady responded well and slowed down the initial stretching. 👌🏼 During the next week I'll give her a bit of stress (breeze) 🌬️😎

After lst the tips of first leaves look slightly burnt and curled, but cotyledons are still green. 🤔 I gave some veg fertilizer and hope she will recover well during the next week. 💪🏼 I'm going to provide more mechanical stress and progressively reduce ambiental humidity...

The burn slowed down and remained limited to the first set of leaves. I moved the lamp closer in order to give the lady more energy, but unfortunately she is still very very small...🤔 D24: given 500ml of water and fertilized. ⚗️ D26: watered, 450 ml of water only.💧 For sure another 1 or 2 weeks of veg are necessary, maybe at 16/8. Pray for me 😁

Hello guys! Overall the plant looks light green/yellowish and pretty small, with short internodes and bottom leaves with burnt and curled up tips. I give water every 3/4 days and commonly suggested fertilzers quantities. How can I let her recover and get bigger? Thanks :)

Hey man, the plant being small is fine, it should explode in the next few days. Just read the comments aswell. Beware of burnt leaf tips. They can be literally anything. Looking at your plant and at your watering / fertilizing schedule, there shouldnt be a problem really. I would suggest watching her grow for a few more days, during that time, try to keep an eye on the yellowing leaves / color of the leaves in general. If they are all lime / pale and the lower ones are starting to curl and turn yellow, you have a Nitrogen Deficiency, so slowly add more fertilizer(and I do mean slowly to avoid an overfertilization - way bigger problem than underfeeding !). And keep in mind that the lower leaves will stay yellow, the not affected ones aswell as the new growth should be a saturated, full and "happy" green. And if you can, keep an eye on watering pH and runoff pH if you do have runoff. Just to make sure no nutrients are locked out over time :) Bless up man

Well, the lady is still very small but overall she looks better and greenish. I watered for 2 times during this week, firstly with nutes and the last one was a flush (small burns are evident in the upper leaves). I'm going with the last vegetative week avoiding any stress. Hope she will get bigger 🙏

The lady is still growing very slowly and is pretty yellowish, not such a big stretch in this phase but at least buds are developing. I watered only one time this week, I'm gonna give some boost the next one. Now the goal is to have a "big" central cola. ☺️

Hi guys. Considering the several problems of this grow, how I can change my setup for the next grows? Now I'm using Plagron Alga fertilizers and the Promix substrate (no fertilized). Do you suggest to set the lamp in bloom mode (more reds) also during the veg phase? Thanks, M

Hi there, Only speaking from experience... 1. More light would be my first suggestion. 90W is kind of low, especially to flower. 2. Looks like the plant needs more Nitrogen to me albeit for the burnt tips. I hit them with a bit of pk at this stage too but I wouldn't with yours because they are not 100% and could mess with it. 3. A bit of calmag may help too? 4. I only flip my plant to flower mode (if there is one) once I see flowers forming. Blue to grow, red to flower.

Not much to say, I gave only water with pH correction and I moved the lamp closer (next time I'll do this from the beginning considering the wattage).

It was a hard growth but finally I had at least a dense apical bud.
