Royal Queen Northern Lights

This plant had a bit of a rough week. I was having issues with my tank heater and I have a feeling it's been going on for awhile and I didn't realize it tell just the other day. It's set to turn off at 21.5c but would always be a degree or two higher when it would finally shut off. UT it looks like it had creeper up to 24-25c a few times and started giving my plant early stage leaf rust symptoms. At first I thought it was a Ph issue because it did jump up to 6.5 a few times and I felt like that might have been the problem. That problem was fixed 2 days ago and it looks to have slowed down the progression of the leaf rust. Today is the last day of veg and the first day of flower is to come. If it goes a full 8 to 9 weeks I'll be looking at a March harvest. If that's the case I might be able to squeeze in a quick auto flower grow before the family summer vacation lol. The temperature has been getting warmer outside and the night time temperature hasn't been to bad. The humidity has been stay around 50% all week and thats were id like to keep it but we're expecting a lot of rain over the next few weeks so we'll see how well that works. I picked up 2 more temperature hydrometer meters with probes for the room. And with all the fans the air movement in the room has been great. Humidity and temperature is the same in every corner of the 8x9 room. I switched the lights from 24/0 to 18/6 this last week to get them ready for the approaching 12/12 light schedule. And because that is tomorrow I lowered the lights down so that tomorrow I just have to turn the lights up. I also emptied my tank and refilled it with the nutrients for flower so that the treys can empty a bit before I add all the new nutrients. I filled all the trays before I turned it all off so they would have enough for the night. Well that's all for now, happy growing and happy new years!!! Keep it growing!!!
