Light doses of CalMag Plus used during veg, but not in flower
MammothP lightly dosed throughout grow (1ml per 2 gal)
MykosWP used in every watering
Versity Bacillus Blend used in every watering
Generic Kelp/fish fert used in every watering
SNS209 systemic organic pest prevention fed first 5 feedings then no more.
Mission Bloom nutes I am using are nothing heavy. About 755 PPM going in.
Room temps maintained at 75-80F and RH maintained at 45 - 55%
Plants are healthy. No burns and only 5 or 6 gnats caught on the sticky traps in 9 weeks.
So I downloaded the Photone app today. Apparently I got the most recent Beta version of it to where you don't use a light diffuser. I put one on not knowing that, and the app detected it and told me to remove it.
So here's the numbers I came up with:
Spider Farmer hanging at 30" above the plants at 75% power
Eyeballing it, only a small number of leaves praying up towards the light. The rest are laying nice and flat.
Through Photone:
PPFD at the canopy is 220
DLI at 12 hours is 9.8
LUX is 13000
Light is 3300K
Leaf temps with my IR gun - 78F
If you have recommendations against the above, I would love to hear it.
Also, now that I am in flower, would you recommend I feed using nutes at every watering, or should i maybe do more like a feed, feed, water, feed, feed, water cadence?
Appreciate the look-see and any suggestions.
Here's the plants after medium defoliation yesterday.
I think you are fine since this is before stretch, but all numbers should be higher in flower .
I would start with lowering the light to the plant after stretch .
Others will chime in with better info then this hopefully .
Ok ... no replies with numbers from you guys "Yesterday" so I had to research. :)
Watching the video of Dr Bruce Bugbee, I cranked up the power to 95% on my SE5000 and dropped it down to within 20" of the plants and then re-measured using the Photone App "Today" to see what kind of figures I would get.
I am pretty surprised that I can't really get anywhere near the ideal PPFD range with this light. Yeah, I had 5% power left to push to 100% and Spider Farmer indicates hanging as close as 8" during flower, but I think that would be a catastrophic failure to the plants.
After I took those readings, since I am only at the start of week #2 of flower, I put the power at 90% and backed the distance off to 24" to let them stretch into it a bit - good call @steamroller
So anyway, I will keep an eye on the leaves and see if they want these lights closer or further by how they react to what it is now.
