All feeds with nutes use either a whole ratio or combination of "Veg Mix" and "Bloom Mix"concentrates DILUTED in water until a total ppm of add in is reached using a (Total Dissolved Solids)TDS Meter measured in PPM (parts per million). The "Veg Mix" concentrate will eventually be added in smaller ratios and "Bloom Mix" concentrate what will eventually replace the "Veg Mix" concentrate entirely with the ppm and ratios listed when I feed. Veg mix recipe is on week 3. Bloom Mix recipe is on week 5.
Day 77/7
PPFD is between 470 and 700 again with little vertical growth after all the HST/LST over last few days. I used 15 minutes of UV mid day with 15 minutes (30 total) IR before and after main light timers.
VPD was better today with 73F/55%RH/40%ILV Turning off the humidifier was the key this time.
All in all she looks fine for the day, I am hoping to get the new tent up tomorrow and will see if I can get her to fully stretch out again to allow each cola enough space to bulk with light and wind
Day 78/8
Tent conditions improved today because I was able to fix the sizing issue - I now have a Spider Farmer Pro-Grade Grow Tent, 48"x48"x80"
VPD is harder to get the humidity down in so I may have to put in a second de-humidifier or open another vent port, currently I have a 6" ILV pulling against a 4" open air vent hole. I would have tinkered with it a bit more but I was getting close to lights out so I left it. VPD for most of the day was 74F/55%RH/40%ILV in the Mars Hydro Tent. I current have 68F/65%RH/40%ILV for overnight.
Lights are about the same as yesterday with 80% power I am getting 470 to 700 ppfd from 42" from soil to light and since the plant is about 20" that gives her about 22" leaves to light. Im currently using the same 2x4 Bloom Plus LED light centered in the tent but I have another 2x4 Bloom Plus scheduled for delivery on Monday or Tuesday. - She had 20 minutes of UV and 30 minutes total of IR (15/15)
I am hoping this allows her to spread out and receive full light/air on each cola - So I also placed 2 more fans in the tent at plant level to help circulate the air better.
Day 79/9
PPFD was little changed since yesterday as was vertical growth (I think she's trying to spread back out again.) - ppfd was between 480 and 710 with 25 minutes of UV and 30 of IR (18/18)
VPD was a struggle to get under 60 - I now have 2 de-humidifiers in teh tent witht the ILV set to kick up anytime she hits 62%RH. Mostly though I was able to get it down to 55 to 61 - Temps are easier to control with 4 fans and the ILV triggers.
Day 80/10
VPD was 74 to 77F today with humidity still pushing 62% with 2 humidifiers today when the tent was closed. Otherwise I was able to reduce the humidity to 35 to 45% with the door open long enough (in MN fall with temps are around 30s)
So I had my door open for a bit today because I installed my second Bloom Plus XP2500 LED lights today and had to reroute most of the wires. PPFD after completion ranged from 550 at lowest to 750 - I only did 20 minutes of UV since yesterday was her first day at 20. I also increased the IR to 30/30 with 15 before and after lights on/off - so a total of 1 hr total at lights on/off
Feels dry so I plan to feed tomorrow morning with about 3 gallons of 6.3ph de-chlorinated tap water feed in a 10:90 ratio of Veg/Bloom mix
Day 81/11
I fed her today with 3 gallons of 6.4ph de-chlorinated tap water with a 25:75 ratio of Veg/Bloom mix at 500ppm. Runoff showed a ph of 6.5 and 1750 ppm.
VPD was more stable today after I opened another open air vent hole on another side of the side. 76F/55%RH with ILV on auto when needed.
PPFD ranged from 550 to 750 again with the lights at about 42 and she's now 34x28wide x22 tall, so about 20 inches from lights. Still only hit her with 20minutes of UV and an hour of IR with 30/30 at main light schedule with 15/15 before and after.
Day 83/13
Almost two weeks since flip. Turning the lights down yesterday seemed to help, little to no new burn progression on those identified yesterday and new growth with no new burn. Will continue to monitor.
Nute transfer seems to also slowed progression with the leaves only turning brown where they yellowed before and little to no new yellowing.
VPD doing better as well - I turned the heat down just slightly so now avg temps are about 73 - 75F and humidity under 59%RH with the OLV set to auto for limit controls
PPFD most unchanged after I started the day with a little LST on the center cola that was getting ahead of the rest. I also released teh last branch being tied - now all colas are simply help by the tomato rings. Once it was leveled PPFD was 750 at highest and about 550 for the lowest.
