Week 6 was smooth. Especially after correcting the signs of deficiency. The plants have bounced back quickly after being fed and are thriving in the environment. New growth shows no new signs of deficiencies, and old growth did not get any worse. Luckily it was caught early enough and corrected. At the end of week 6 I continued to tie down shoots and continue the LST throughout the canopy. Light defoliation was also done around prime bud spots, and the lower skirt near soil. Technically also removing lower growth that won't amount to much, aka "lollipoping." Plan for week 7 is to continue to water when dry to a PH of 6.2-6.6 and LST with light defoliation where needed. Monitoring the environment and running dehumidifier to 45% RH. Fans are blowing and these seem like they will be big girls. These are some of the bigger autos I have seen personally.
*UPDATE* One plant is showing nitrogen toxicity. Leaves are curling bad at top. I took her out and flushed her, as I may have built up too much with run off when fixing the phosphorus issue. Continue to monitor and hope it recovers quickly. But have also seen a lot of other grows with similar leaf traits with downward curls, might be genetics. None the less, will let dry and water thoroughly all plants next time with PH 6.2-6.5 water.
*UPDATE 2.0"
So the girls soil was not good. Turns out my calibration was off on pH meter and was flushing with around 7 pH water. Read the soils and one plant, that had the claw and dark leaves, was above 7.0 soil pH. Others were below but still a bit high. Have been adjusting pH of water to about 5.8-6.2 pH for next few to help lower it. One girl is not happy. We will get the train back on the rail though.
