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 70/0
Flipped to 12/12 - increased ppfd by 100 and worked to stabilize temps/humidity with new gear. I used 15 minutes of IR light before main lights and then 30 minutes of UV light at mid day and will still use 15 minutes of IR light after main light are out. I plan to increase the time of UV lights to a max of 2.5 hours per day mid day but for now Im easing her into the treatments.
Watered with 1.12 gallons of 6.3ph de-chlorinated tap water, used 50ppm of veg mix and 50ppm of bloom mix in the water. VPD is mostly steady 74F/65%RH/33%ILV
Day 71/1
tested and calibrated my meter, tested the top soil 1 day after feed for ph - tested 4 times for an avg of 6.48
Trimmed brown leaves and did some HST/LST training/binding. Took control pics for UV treatments of 15 minutes per day. Will monitor and increase weekly it she holds up okay. Still doin 15 minutes of IR light before and after lights on/off.
PPFD after training was 630 at highest and 540 lowest. VPD was 74F/60%RH/33%ILV
Day 72/2
Just a watch today, VPD was 75F/60%RH/setting 4/10 of ILV (about 33% like the last tent)
PPFD ranged from 530 to 650. I only used 5 minutes of UV light today as she has a tinge of browning on the tips of a few leaves. Im not cutting it out completely because I still plan to use upto 2.5 hrs by end of flower, so she needs to adjust. Im also still using 15 minutes of IR before and after main light schedule.
Her stretch seems to be picking up, from 16 inches 2 days ago to 18 today.
Day 73/3
VPD same as yesterday 75F/60%RH/40%ILV
PPFD hit 670 at highest and 550 at lowest. Stayed with 5 minutes of UV light and monitored burnt tips from previous days... no spread, so I may add 5 more minutes tomorrow and monitor. 15 minutes of IR before/after main light schedule.
Growth continues, another inch in stretch to 19 inches. I turned her slightly because there are still two runted colas that I rather provide more light to. It's been 3 days since last feed and I think with as much growth as she's putting on, I should feed again tomorrow. Im still introducing nutes in lower portions but will add 300ppm and feed about 2 gallons at a 25/75 ratio of veg:bloom mix to see if I can get some run off to measure conditions.
Day 74/4
Watered with 2 gallons of 6.4 ph de-chlorinated tap water. I added 300ppm total of 25% Veg/75% Bloom. Starting ppm was 296; ending was 595 and I added a pinch of epsom salt. Poured over the whole base until I got runoff - Since I was so close to the whole 2 gallons, I used it all. I only used the feed water over the roots today as I want her to get the nutes from the soil since the transfer into new soil was so recent.
So far VPD is 75F/60%RH/40%ILV. No issues with controls.
PPFD was upto 700 at center so I raised the lights to almost 42" from soil - Since the plant is almost 20" that's 22" leaves to light. New PPFD now ranges at 480 to 650 on 70% power.
I increased UV time to 10minutes today and took control pics for light burn. I am still using 15 IR before and after main lights.
Took some black back picks since I think she's looking good now.
Day 75/5
Started the day with evaluation of ph and control pics. Comparisons show no further spread of lock out issues from earlier or light burn of a more recent change. Upto 20 inches before HST/LST today.
Meter was tested/calibrated and soil ph was tested 4 times for avg of 6.34 (yesterday's runoff was about 6.35 too) Soil temp is about 66F. Also tested CO2 and got 1050. Room VPD was 74F/60%RH/30%ILV
I spread the leaves further apart because I noticed there were two colas not getting as much light and somewhat crowded by the colas near by. So I positioned the larger part of the tomato ring around the limbs extending here out to 32x32 and the used HST/LST to break and bend the center colas inward clockwise (I think I went a bit too hard on one as the others already show a bounce back and now one is still limp-ish (will monitor obviously) But with that the height is now 18" so 32x32x18 - but here's the kicker, I only have a 24x48 tent, so there's a few colas touching the walls and doorway now, so I may have to reconsider the larger ring.
New position, new PPFD right?, not exactly, for some reason these settings still gave me range of 480 to 650 as I had yesterday with just a few more of the outer colas have 480 than yesterday. However, there's more light getting lower levels now and I only had to cut 1 leaf. Which is good because I did 15 minutes of UV today with the regular 15 minutes of IR before and after main lights.
Day 76/6
VPD is a lil wonky now as humidity is starting to go up in the tent - so I plan to put in the dehumidifier this weekend and just leaving the humidifier off today and tomorrow. Heat seems to also be ticking up - so I reduced the temp on the heater and will monitor. Temps about 75 to 76 - humidity at about 62% as high as 65 though and Im trying to be at or under 60 this week. Increased ILV to 40%
I repositioned the fans to hang on the lights while blowing down onto the plant. I tried to make every leaf dance a little.
LST seemed to hold up okay - had to reposition a few branches and thinking I may have to build a larger box this weekend since the colas are now pressing the door and back wall.
PPFD is between 470 and 700. I used 15 minutes of UV mid day with 15 minutes (30 total) IR before and after main light timers.
