Dear all,
I hope your grow is going well. I am a newbie, in my first indoor growth. I will bombard you all with a bunch of questions but before, let me elaborate on the specs of the build: 80x80cm tent with a mars hydro ts 1000, Dospel 100 m3/h fan with a 6 inch carbon filter, 25 cm diameter fan for inside air circulation, small humidifier.
I have germinated the plants using the wet paper towel method and then put them in 200 ml cups filled with Biobizz Lightmix (slightly flushed). They all sprouted up and upon showing the first fan leaves, I transplated them into 5 gallon pots with Biobizz Allmix. I've made sure to keep the rootball and soil from Lightmix in tact. It has been around 11 days after putting the seeds in the wet paper towel. The plants I have are 2 Purple punches and 2 Fat bananas from Royalqueenseeds. One of the flowers(purple punch) is currently showing a second pair of fan leaves. Hence I was thinking about fertilization. I saw a video from Mr Growit where a wrong sequence of fertilizer mixing in the water can result in white residue which messes up the mix and ph levels. Hence, my question is how exactly do I mix the fertilizers? I have Calmag, Fishmix, Biogrow, Biobloom, Topmax, Rootjuice, Algamic and Bioheaven.

Should I give them water in a daily basis or in 3-4 days? I feel like it's good to dry the soil out before the next watering to prevent any mold and enhace better root development. Also is there a technique of watering them? I've seen a lot of people go around the plant in a circular motion.
In addition, what about the light schedule? I know that autos are ruderalis, which enables them to flower without having much light. But the ruderalis percentage in my strains are relatively low, hence I was thinking of giving them a hybrid lighting schedule(20 on 4 off in veg, 18 on 6 off in flower). Maybe even give them 2 days without light at the end of flower. What do you think?
Also what about CO2 bags? I've read so many mixed reviews about them, some claiming it is useless due to how the air circulates around the tent. But I was thinking about getting one, since I sometimes turn the fan inside off to increase humidity levels(the Dospel fan), and this could also result in the CO2 particles falling on the plants' soil and leaves.

Thank you in advance and happy growing))
Thank you for the help)) they are doing fine at the moment. Gave them 2 ml of rootjuice and 1 ml of calmag with distilled water. Turns out ph of water in my region was 8.
But i have a different problem now. One of the fat bananas started to show signs of either spider mites or leaf septoria. Not sure which one it is. I've put a cup of wine mixed half with water in the tent so that it would evaporate and sulfur kill the septoria fungi. I've read that water soaked with chamomille tea helps, by spraying it over the leaves.
