Started pruning and LST this week. She'd probably be 12-16 inches tall I'm guessing if I were letting her grow upright. Hope I'm doing it right. 😂 Fed normal amount this week, she responded well I think initially, I noticed a slight yellow on a single tip of two different leaves right next to each other, centrally under the light. I moved the light closer based on a less than perfect ppfd reading from the ppfd app using my phone. I suspect those leaves were getting slight leaf burn from moving the light, but just in case, reversing the watering and feeding next week. Still watering when needed, roughly twice a week, 2000 ml each time and feeding every other watering. Also switched to ml because it's easier and I have measuring cups that weren't being used, so why not?
THIS WEEK:
*TARGETS*
RH - 65%, +/- 5% offset (No automations set, statistical only)
Temp - 75F (max low none, max high 77)
VPD - 0.9-1.3kPa, controlled by automation. (Dehumidifier turns on at 0.9 or below and turns off at 1.3kPa.)
*WATERINGS/FEEDINGS*
First watering (day 21): 2000 ml water didn't water until run off this time. Fed Fox Farm Big Bloom 15ml and Grow Big 5ml mixed into water. PH 6.5.
Second watering (day 24): 2000 ml water. PH 6.5.
*ADDITIONAL NOTES*
Dehumidifier in the tent was the ticket. No more humidity spikes and if not for me getting the probe wet and then not noticing I left it on the tent floor after trying to dry it, VPD probably would have been in range all week. Once I noticed two days later, there were no VPD issues or humidity issues afterwards.
Also stopped using the heater and just letting the temperature alone at night. It doesn't get below 65F here for anyone reading this.
All good things come to an end! This next week will be the final one for this girl. It's been fun, can't wait to do it again! But ready for harvest until then.
So it was pointed out to me that while my phone has a macro lense, I was using it wrong, so now I have better pictures of trichomes for the this week once it is over.
It's a waiting game of is she ready now I guess? I'm hoping the temperature issue didn't cause anything major. It was about an hour before I noticed. The leaf colors are kinda of concern for me, but the rest of the plants looks okay otherwise. Trichomes are mostly cloudy I think 🤔. It's honestly hard for me to tell.
Slight discoloration in the leaves, which I'm attributing to overfeeding Open Sesame and Beastie Blooms. No other issues observed so far. Some lower leaves have fallen off here and there, not no major issues that I've seen.
Intake fan and filter were added, have AC exhausting outside rather than into another room. Next week I will be exhausting the tent outside the room as well. VPD is now dialed in to the range I set and never gets outside of it. The AC automation isn't working properly and I have a request in to that company, but in the meantime, I have alerts tell me when the temperature gets too high, then I manually turn on the AC and automations work for a day afterwards.
She's growing out more than up. Going to install an intake fan and get it going with the exhaust fan, as well as exhausting outside instead of in the room the grow tent is in. I will probably move the dehumidifier to this room when that is done since I'll (in theory) be able to use that room better to regulate grow tent conditions.
Humidity has been going up during lights out, humidifier is on the way. It only gets down to about 65 at the lowest at night, but the 5-10 degree or so drop is enough to make the humidity shoot up, which in turn throws the VPD off. Hopefully the dehumidifier resolves it. Will update at the end of this week.
