Thank you Sir!!
make sure ur tap water bubbles for at least 24hr to get rid of most of the chlorine, but if you dont know what the PH is it easy to get ur PH way off and lock out certain things. maybe a cheap pool PH test kit will get you in the ball park. at least so u can see what ur tap water PH is?
when using good quality soil should have enough food to feed ur girls for a while worm castings, meals, guanos, ect.. i would recommend sea kelp for sure though mixed into ur water.
Now with the led light hight its hard to say because i dont know what brand u are using? ive tried a few different types of led lights in my time and they all like different heights. I know the better/stronger GLH lights are a good idea to start off high and work ur way down, to harden off ur plants.
As far as the dome it worked wonders for my one girl, the others came back with just good micro life i believe? but the dome i just sprayed R/O water on the inside and put it over my girl and took in of every maybe 3-4 hours and left it off for maybe 15-30min and put it back on. the moister in the dome is what keeps the plants from transpiring allot.
When cutting the leaves its best to cut some of the fingers off that are the older growth and that are too big and bulky for the roots. dont cut the whole leaf off just the fingers. just like you see with allot of clones when you get them from a good cloner.
Now please dont take my advise as the right and only way of doing things. this is just my opinion and what i would do. in no means am i saying this is the right/only way of doing things. you must take peoples advice and run it threw ur head to see if it makes sense and do some Google searching. the last thing i want is to be at fault if somthing i said messed up their plants
but this is what ive done and what worked for me.
by the way from the looks of the 1st pic you have the dreaded "CLAW" i have no clue what it means for 100% sure, but ive read before it has something to due with Nitrogen, but maybe do some goggle reading on "the Claw with cannabis plants". or something like that.
