Auto mix

Most soils mixes have organic materials that break down. It’s common to see a bit, but too much can be harmful for your seedling. Keep your soil moist, but not saturated- and I’ve heard hitting the top layer of soil with sine ground cinnamon can help keep the mold from becoming an issue 🌱

You can boost the light to 100%—- just make sure you have enough distance. Seedlings are at least 24-48 inches away from my 660w beast at 100%. For fast growth—- I don’t feed nutrients to my plants until week 3/4— however I do feed them microbes. Microbial life hydro photosynthesis plus—- and mycorrhizae… big boosters! Good luck! ✌️🏻💚🌿💨

I have always used 100% and both the grow and bloom lights switched on from day one until harvest. This works for me and I just vary the distance of the light from the plants. About 60cm is ok for seedlings. If after a few days they look a bit elongated/stretched, move the light closer. If this plant is one week old, it is fine, if as it says in the picture that it is 3 weeks old, it definitely needs more light. Hope this helps, Organoman.

I'm no master grower but the best thing that I have found is to follow the manufactures recommendations. Mine seem to like 30" from the top of the canopy at full blast. Running a 650W full spectrum LED. I personally gave my plants until the first true set of leaves were grown in before upping the light. Keep an eye out for heat/light stress. The leaves will start to twist and get wavy when that occurs.

I'd recommend pulling the water back and making sure it is the proper ph. Seems like over watering/nute burn.

Potrebbe essere un over, prova a dare 2-3 volte acqua con ph 6,3- 6,5 . Buona crescita amico spero di esserti stato utile

Your ph is set at the low end for soil growing. 6.5 may be much better for your girls. If your seeing leaf clawing, then that's a sign of to much nutrients. When growing in amended soils, feed shouldn't be added until you see they need it. A plant that size would not have used up the nutes that were already provided in the soil. Cheers
