Basic grow

Hi all, It's the end of the sixth week and she's been having a tough time. On day 37, about 4 days after the mini flush, she was still showing bad signs of feed problems and imo block so I decided to give her a heavy flush. 30l of pHd water in 3l increments with a 10min pause between each wash, pH testing before it went in and after it came out. I had no TDS meter at the time so I couldn't check but our water is extremely pure, 56ppm, so that wasn't a worry. The last liter went in with food to replace what I'd washed out. .5ml CalMag, .5ml of grow and 1ml of bloom and topmax. In between I've been taking off some of the nastier looking leaves. If you look at the pictures you'll see that her pistols have changed colour relatively early. There are no signs of pollination/hermaphroditism so I'm putting this down to the stress of the flush.. I gave her a little spray of biobizz leaf coat, just for the he'll of it. I'm going to be testing TDS from now on. Hopefully this will let me confidently raise the nutrient levels of bloom and topmax and get those buds going. I'm also intending to raise the amount I water each time to 1.5l but lower the frequency. Hopefully she'll buck up a bit in the coming few days but for now... Tune in next week, same bat time, same bat channel, for another exciting episode!
