3 Bears OG by Mephisto

Day 51 Sometime between the last watering and yesterday I seemed to have lost my pH pen. My water is 7.4 and when I feed the nutes balance them right to the sweet spot. So feedings should be fine but my waterings may be a a worry. Not sure how far past 7pH the plant will take. I'd really hate to fuck things up at this point. She hasn't been fed since day one of week 7 so she's getting a half dose today applied through two liters of water. pH is definitely in the mid 6's. rH is 50% this happens when she's thirsty. Temps are around 26°C this morning. Was probably a little colder then 20°C over night. Bud sites keep swelling. Some of the lower branches have bigger buds at this point. She's still got a ways to go yet. Very excited. So after feeding the plant 2.5ml per liter through 2 liters of water I noticed some slight burning on the tips of the upper leaves. I raised the light a bit, the plant is still stretching a little, about an inch over night. It's going to be straight water for the next while. Light defoliation Day 53 Applied 2 liters of dechlorinated water Day 55 No signs of toxicity advancement. Bud sites continue to swell. Temps are in the low 20s, humidity is between 50 and 60%. Overall she looks happy and that makes me happy. The plant is well I've 2 feet around and I easily could have filled a 2x2 tent with her. I plan on finishing her out and starting 4 more for my outdoor grow this year. Then getting a 2x2 to do scrog method over next winter. Day 56 Plant still looks happy. Probably need water tomorrow. Pot is still a little weighted. Temps and humidity are consistent. Lost my pH meter. No signs of problems yet.
