Moby Dick XXL auto and blue amnesia XXL

I use all 3 General hydroponic nutrients and they are two different pot sizes the Moby Dick is in 30 liter and the blue amnesia is in 18 liters has a very strong odor and blue amnesia is maturing at a faster rate then the Moby Dick. a scrog net is being used in order to give support to the upcoming buds. I am also actually on week 4 I just made a mistake calculating the week. this is my first grow ever. also I'm not sure if using the scroll net it's a good idea for support rather than tying those branches up . I am watering every two days feeding nutes every single time at 900 to 1000 PPM ph at 6.2 the plans have not show any signs of stress but I am worried if it is too much nutrients the plant seems to grow very fast after every watering and seems to be loving it. the blue Amnesia XXL Auto it's growing in soil with 30% Coco and the Moby Dick XXL auto it's growing in hydroponic soil. the seeds were germinated on jiffy's and 100% germination rate plus the genetics seems to me very resilient to heat and everything else including lots of nutrients. the moby Dick XXL auto are the two in the front closest to the camera the two farthest to the back of the tent are the two blue amnesiaXXL auto. today day 31 i did some pruning actually lots of pruning hopefully don't cause stress to the plants or even worse cause them not to bud that nicely regardless the scrog net seems to be working just fine helping them access more light and making it easy for cutting leaves that are no longer needed. 32 yesterday after watering and sleeping today they have show no signs of stress in fact they starting to stretch in the buds that we're not getting sufficient light have start to grow also yesterday from the 16 liters I prepare instead of 3 ml of grow formula I add 6 1/2 to compensate for stress and the need of healing and having new grow stretch. also temperature has dropped dramatically outside making my house cold down from 24 degrees C to 19° at night internal temperature is remaining the same from 30 to 26 C. Day 33 I have been raising the scrog net every day and the light everyday this plant is growing very fast I also notice that where the fan is hitting all the time that plant is bigger I have been moving the fan to other sections of the grow tent to see if any reaction happens and it looks like it makes the plant grow faster . I will not be moving the Scrog net any higher Rather I will introduce another one once they require more support . Day34 notice some of the top leaves are showing a curving down like over-watering without actually over water I think they're showing signs of too much nitrogen .for the next water session I will hold back on nitrogen until I see signs of a fully recovering meaning leafs pointing up. thank you for reading have a happy grow.
