Triple auto first indoor

4 weeks from germination, still on the small side. I turned down the led lights to 25%, they were way too high at 80% and it looks like that contributed to stunted growth. Within 5 days the plants started stretching, I gave them a good watering with a bit of grow nutes and spray the leaves with water and a bit of aloe vera and kelp powder once a day. Temp stays at 22 day and 19 night with humidity between 50 and 70%. Desertclimate here so tougher to keep constant. I hope they somewhat recover so I can still get a few gram of them. I terminated the lemon AK, it was not healthy. For next time I'll put one plant in one pot, lesson learned... Stems hardened already so don't want to risk LST on the main stem, I'll see how it goes. Also, the soil starts to smell a bit sour on and off. I read it up and this indicates, bad soil, bad water drainage and or too thick soil but I used 40% ordinary potting soil, 30% perlite and 30% coco coir so it almost can't be bad drainage. I tested by giving it the good watering and it came out through the bottom in a minute or 2 so it must be bad quality middle Eastern soil. I ordered biobizz all mix for next growth
