What does she want?

+Speed Auto from Sweet seeds on week 5 (33 days) from seed (breeder claims 7 week strain).

Medium is 1,5L of Plagron Batmix in fabric pot.
Water pH is 6.0 - 6.3
Lights are Migro 100 at around 30 cm above the plant.
Feed her once tree days ago with:
BAC Organic Bloom (6-5-6) at 0,5ml/L (¼ of recommended dosage)
Organic PK Booster (3-3-8 ) at 0,25 ml/L (¼ of recommended dosage)
Bloom Stimulator at 0,05 ml/L (½ of recommended dosage)
BioGreen Calgel at 0,5 ml/L (full strength).

Does she lack anything or got burn? What may cause that spot and discoloration?
Thanks for any input!

If you're lacking anything it appears to be a little Mg, otherwise, your girl looks good!

I have no experience with what you are using as your medium, i actually never heard of it No idea about what you are feeding as i never heard on any of those either lol): All i can say, and it may not at all be because it's lacking, but may be too much calcium or potassium causing it, but that, like mentioned above, is related to a lack of magnesium in the plant. I won't say to add more as again, i have no idea what you are feeding, it may be getting locked out from all the other stuff going in, especially since it's a very small auto, it likely doesn't need all the extras, but ya, the symptoms are for sure, plant not getting the magnesium it needs.

Thanks! Will back up on feeding for next couple of watering.

I'm with Blitz35 here; it's hard to make suggestions not knowing fully what you're working with. Epsom salt will give you the Mg you need, but as noted, it may be that your Mg is locked out, not so much lacking per se. I would investigate what you're feeding your plants, along with your soil to see how much Mg is already in your soil and feed. If there isn't any or very little, then adding some via Epsom salt might be a wise move, however, if what you're feeding has a lot of Mg in it...I would research what locks out Mg in cannabis and go from there. Being she's an auto, I would do things in small steps and gingerly; you can't afford to upset her much at this point.

Thanks! I will check what soil bag says. Nutrient bottle doesn’t says anything above N-P-K levels and general “contains all necessary micro and macro elements”. Giving it is organic one can't really know what is in there.

Call the nutrient company you use and ask which micros it contains and how much of each is in it and write it down. If they won't tell you, I'd start looking for a new nutrient line.
