Fade to Blackberry

THURSDAY 12/13: I really blew it with this grow..the PH fluctuations last week were not well received by Beatrice at all. She'll lose most of her foliage over the next couple of days and I doubt she'll still have the energy to put on much more size on her buds...😫 FRIDAY: She's hanging in there..lost some leaves, but buds are still swelling. SATURDAY: She was still too moist from the flushing to feed her. SUNDAY: I fed her today with full strength bloom nutes and some extra boomerang. MONDAY: Beatrice is still recovering from PH fluctuations that made it seem as if she had a half-dozen different maladies at once..boron deficiency, overwatering, N toxicity, and light burn. Now I'm starting to believe I'm dealing with actual light burn! I think the new lights are just too intense for the distance I have them at...at least at this stage of flowering. I've dimmed them to 90% for now... TUESDAY: I fed her full strength bloom nutes, plus extra boomerang. In addition to the light burn issue, the new lights lower the RH in the tent waaay too much, so I've temporarily got a 4-liter cool-mist humidifier filled with ice cubes running for about 10 hours at a time before it goes dry. That's raised the average RH from 21% to 28% and lowered the average temps by a couple of degrees as well...still not good enough. So, I ordered a small evaporative cooler to put in the tent, up on the shelf. It holds a little over 2 gallons of ice water and oscillates. The new light is IP65, so a few drops raining down here and there should make no difference, but the added cooler airflow should really help to bring up the RH and lower my average temps. WEDNESDAY: The two new 85w individual OSRAM bar lights came in today and I hung them in the 1-foot wide area just below the shelf. Now I've got awesome coverage all the way across the 5 x 4. They put off some heat and I don't have any plants under them right now, so they are turned off. Love the spectrum they produce..the white is 3200k..but they just have 2 x red diodes every 12 inches of bar, whereas my 10-bar fixture has 3500k, but 6 x reds per 12 inches of bar. The OSRAM diodes are every bit as bright if not brighter than the Samsung LM561C diodes, but all those deep red Cree XPE's on the fixture give it a much better spike in the 660nm range. It will be awesome being able to independently lower the lights in a 1' x 4' section of the garden. When you have dwarves to deal with, it's so much better than putting them on buckets.. That's a total of 1010w actual draw watts at full power in my 4 x 5 tent...sweet...just gotta get the RH and temp under control. It would take a seriously full tent for me to even consider turning on the extra 100w of side lights...but they're there if I need them 👍
