Pheno hunting some strains

So it was an interesting week... I had a problem with spider mites, seems that alot of spider mite going around in my area right now, but onward I go. My veg tent has multiple cutting from some other strains I stared months ago and seemed thats where most of them made their home. I took everything out of my tent washed it out completely, sprayed every plant with some insecticidal saop as they are all quite small still I feel confident that I can take care of these with a couple treatments of that, also my local hydro store gave me some acid to try (never tried before but he recommended it) might try that if they don't subside after the insecticidal soap. Otherwise the plants them selves look great and are growing quite well still just watering with R.O water at 6.5-7.0 I'm thinking about transplanting to a larger pot soon amending the soil with fresh nutrients till next week keep growing
