*6/2 Light* - Summer Pink Kush

Hello all, Pretty static so far going into Week 4 of flower. Hoping the stretch has stopped. Strawberry Lemonade and Pink Kush #1 went to battle for height at the front of the tent with Pink Kush #2 throwing out a Lanki Boi out of nowhere to be the tallest branch in the house!!! Funnily Enough, the back of the tent, even though the light was very central in the tent stayed relatively stretch free, just the mid section under the bulb went balls to the wall...maybe I was too close but thought the lower light at the back would make them come up looking more? Dunno...could be something with the parabolic throw. Only change this week, apart from concentrations, is I added Sumo Active Boost as no longer Nitrozyme spraying with flowers there. Don't know if its needed with Pure Blend Tea but hope it can do no harm...apparently it helps with the uptake of P & K so lets see. Didn't add PK Warrior 9/18 as I didnt like what it did to my water last time making it incredibly acidic (Like a drop from pH 6 to 4.7 overnight) so leaving it out as don't know/don't think i should need it with the levels I am using of Kind bloom. Apart from that, general tidy up and letting it all tick over. Happy Growing all.
