5 x Afghan Skunk Fast - 400W HPS

third week after clones went into soil.. unfortunately I didn't started with photographs sooner but what I did so far: week 1: - clones of 10cm height received and went directly to 11l pot with watered soil light mix with perlite (of which roughly 10 - 15%) - I built DIY humidity dome around each clone using sticks and food foil with holes.. I sprayed inside water every now and then.. - during this time they were under 400W HPS.. temperatures around 25/28 during day and 17/18 during night ( yes I realize this range was maybe too high) - first full watering 3 days after putting them to soil.. I used 1.5 litre per pot (maybe too much I know) - clones were thriving.. all five were visibly growing leaves, no sign of any problems week 2: - I bought 250W MH light so I changed it.. temperature inside the space lowered to 22 during day and 17/18 night - soil was drying very slow - I suppose because of low amount of perlite (next time I'll be smarter about this) - next watering was 8 days after first full watering (when soil was visibly dry on top and moist one knuckle in) - I used Advanced Hydroponics Bloom / Veg / Micro with half of regular dose - again 1.5 litre per plant - plants had already over 20cm on main cola with few 4 side colas on each - I did first topping shortly before watering them.. I cut main cola on each and cut it quite low (maybe too low) - I'd say not even 10cm was left of main cola with side colas branching from there already - I also started using oscillation fan.. another mistake here as I read somewhere that I should point it to soil to help with drying out.. so I pointed to soil but to plants as well. Soon I started to see effects of Wind Burn and I believe they are still visible on some plants (dark leaves curled down) - I did some LST.. as some plants were smaller than others I tied down some branches to the pot to stretch it to the sides a bit - I defoliated a bit.. the leaves plant had from beggining - when you receive clones some leaves are on it but they are shortened.. so I got rid of these and I can't see any harm done week3 - tomorrow next watering.. now with full recommended dose of food - I'm thinking about next topping to have more colas MISTAKES SO FAR: - add more perlite to soilmix .. 30% at least - oscillation fan should not point to the leaves otherwise they'll burn - maybe I won't top that low next time - air humidity is low.. it's between 40/45 %, I'm using air humidifier and I can't get it to higher level no matter what I do.. plants doesn't seem to care too much though - I'm afraid temperature is low QUESTIONS: - soil dries 7 days again.. I plan to use less water and maybe I should just drill some holes using pencil to make it more airy? when creating holes I'm bit worried about roots and potentially hurting them - should I do next topping? after first one it took some time until plants recovered and they are still quite low.. considering I'm in middle of week 3 and I should switch at the end of week 4 (I'll maybe give it another week of grow anyway) - as you can see some leaves are clawed.. I think it's still result of wind burn.. but maybe it was symptom of over-watering? it's difficult to tell I'd say - SCRoG - I still haven't decided.. I would need more colas for that.. at least 8 on each plant meaning I need to top every cola I have again.. any idea welcome :) - do you think temperature is too low? 22/16 is not that much
