WHAT I DO DO IS YOU CAN REMOVE A FEW OF THE LEAVES THAT ARE NOT NEEDED ON THE NOTTOM OF THE PLANT TJOUGH AFTER WEEK 4 TO 5!!!! DEF MSKES MY PLANTS PUT A LITTLEORE ENERGY TOWARDS THE TOPS. BUT JUST DONT CHOPPIN AWAY OVER THER BRO!!!! WAIT TILL IT ABOUT 40 DAYS AND YOU CAN SEE WHAT IS AT THE BOTTOM THATS CLEARLY NOT NEEDED AND IM TALKING ABOUT 3, 4 OR 5 LRAVES EACH PLANT!!! THEY ARENT BIG ENOUGH TO LOLLIPO OR ANYTHING AND WERE NOT GROWING BANDAIs or something!!! I went a little YOO HEAVY on the nutes in the begining week2 and def saw a little yellow but pulled back, flushed with filyered water and gradually went up with the nute intake! 3-0-4, superthrive, blossom/bud set spray, big bud, bud candy and overdrive and THEY WILL SUCK UP ANYTJING I GIVE THEM NOW. I ALSO dose them with organic blood 2 -3 times afyer week 4. Good luck keep is posted.
