'Northern Lights' by i49

Hello and welcome to Week 10 and end week 1 of flower with Northern Lights. The Good: -Still very happy with the NL's. They're growing very well and with the stretch they're gaining height at a very quick rate. NL #2 two moves quicker then her sister, but both are looking pretty good -The slight Nitrogen toxicity from 1.5 weeks has not returned at all and the flush through performed has once again done it's job and removed any excess she doesn't need while replacing it with what she does need/want. -Forming inwards is going well, branches are getting thhhhick and firm. I removed tyes to see if she moves, and she does not. This may change with cola weight, but they're carrying themselves very well as of late. The Bad: -Weather, weather, weather. Going on to 12-13 days of -35 to -45 degrees Celsius (with wind-chill). I haven't felt these temps for 8 years or so, and I don't miss it. It is terrible for anything living and the plants are no different. Temperature is under control now, but RH is a constant battle. This is a very dry cold and the house is hovering around 20-25% RH. This sucks the moisture out of everything, like our skin and our plant leaves water retention reserve. Symptoms observed and actions taken are listed below. All things used or done were either very cheap or completely free👍 -Space restrictions are very tight. I have total projected height calculations listed in Blue Cookies, Week 10. There is not much room and I can already see that triggering at 24" was not leaving me with too many options if one of the girls decided to grow like crazy. B.C and NL #2 are those out of control girls right now and only time will tell where this'll end up and what I may have to do to reduce heat/light stress. The 'Meh': -NL's (especially #2) are still 'praying' and cupping even with the light backed off at a good distance. I realize now that this is more an issue with RH then my lamp intensity. So, leaving the lamp where it is and working @ balancing out the RH instead. -Want to use the blurple but keeping out of commission until this weather sorts itself out a bit. I do not want this additional lamp to burn off the only humidity I was able to correct, putting me back at square one😕. Looking at the forecast, I do believe I can put the blurple back on by the end of week 2, Bloom. ***Weather Conditions and simple remedies:*** As stated, the weather is bad; very bad. The cold isn't that bad to mitigate and it was relatively easily to do with a small ceramic heater or using my lights as my primary heat source. The issue lies with the relative humidity. The world is pure static and my home is seeing about 20% RH (25%) if I'm lucky. I noticed all plant leaf edges burning, top to bottom and didn't know low humidity could cause faster eating, or that our leaves will siphon whatever they can from the soil when in this state. So, even though I didn't have a Nitrogen issue, all plants burned slightly as they were taking too much from the soil, too quickly. After this research I knew that RH had to be adjusted...or else. Symptoms of low RH: -Fast eating, fast drying. -Leaves lose majority of moisture and they become very papery to the touch. -Plants start taking up too much Nitrogen (or anything it can) from the soil which resulted in a top to bottom leaf tip burn (If left alone, it would persist) Remedies (Cheap and/or free): -I don't like to have standing water in my tent (especially after my gnat issue) but I had to add a pan of water, placed on top of my 32 watt heat mat. This gave me about 7-10% additional RH but wasn't enough. -Hung large tea towel close to, but not touching the light. Clip on fan is cascading air over this tea towel and I can achieve 40-45% total with these two methods -There is always the tea towel, bowl of water and hanger method too, that I may implement if RH continues to fluctuate so wildly. ***End*** Notes of the week: -No early week photos included this time. I do not have them. I was far to pre-occupied with fixing the RH issue and DSD's Nitrogen toxicity issue that I forgot to take my progression photos😢 -After two consecutive applications of Emerald Harvests Sturdy Stock, I do believe I am observing a difference in the strength and form of my lateral branching. They're firming up very well and holding well. I may be incorrect but the EH is the only thing I feel I can attribute this too as it's the only change I've made to my schedule in the past 2 weeks. -As we move along, we're going to slowly drop the N/K and pick up the P/Cal supplementation. FloraGro is almost irrelevant now since FloraMicro covers the Potassium needed and the dose of Gro is almost negligible as is. -All training wires have been removed over the course of the week and there is nothing holding her back. Only bracing from within the inner canopy has been applied (Off 2 foot and 3 foot bamboo with paper clips) -Picture of blanket and clips used on lip of tent to help mitigate any potential light leaks through zipper tracks. I'm paranoid and noticed these when I did my 'dark' test before flipping. The dual zippers are not broken in yet (still new tent) and light DOES come through the track. I taped the other side up with the non-residue tape but I needed access to this side window, so the blanket was my solution and has proven to block out any extra light (Tested👍) Thank you for stopping by this weeks addition of Northern Lights! Any suggestions or concerns you have from the photos? Please contact me through PM and let me know! Cheers and happy grows my friends👍😉
