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).

Grow Questions
ElLoco week 1 started grow question 2 months ago
The stem is pretty long (4-5 cm).

Is it normal for this strain?

Thanks,

Move her closer to the light a bit. When you transplant you can bury her to your liking.:+1:
ElLoco week 4 started grow question 2 months ago
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

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.
