Hi all-
Firstly, thank you to the Rollitup Community. First time grow - done my homework but have certainly been learning as I go, much to the credit of such a great resource as RIU.
Anyway, ran into a problem the other day and need some opinions - last thing I want to do is misdiagnose and/or overreact.
Strain: unknown, bagseed
Growing Medium: Black Gold Potting Soil, 5 gallon pot
Water: ~weekly, once soil completely dried out but before leaves began drooping
Nutrients: Fox Farm's Trio
Training: LST
The plant was grown from seed through its vegetative stage indoors next to a west, south-west facing window with direct Californian sun from a little after noon until 8, with at couple of hours of sun with the window open, wind permitting. Was hoping to vegetate a bit longer, but plant began flowering as SF summer fog set in. Plant seemed to do relatively quite well (favorable opinions on window grows seemed mixed at best). Had one minor pest problem - due to other herbs growing in indoors - but was remedied with the help of a lady bug army. Did not begin feeding nutrients until the BG Potting Soil ran out of Nitrogen and a few old fan leaves yellowed. Plant went through a couple of weeks in flowering stage and recovered nicely before being transported to a new outdoor, sunnier location as sunlight is likely to remain sporadic for the next couple of months.
Since the big move, the plant has developed a couple of issues. Of chief concern, the plant has developed rusted brown and yellowing on a few fan leaves. Since it is an LST grow, there are quite a few bud sites... the problem is affecting both newer and older fan leaves - but only the fan leaves, overall. The plant now receives directs sun from about 9am until sunset, ~8pm. It also has slightly warmer day temperatures and colder evenings since it's outside, as well as increased wind - but not nearly as a big of a fluctuation as the direct sun it receives. Temperatures average low to mid 50's at night, 70's during the day.
Secondly, a couple of leaves also developed tiny white spots which I believe were mite related but have seemingly been taken care of with more lady bugs, garlic, and a touch of diluted neem oil (carefully applied to targeted areas, away from buds).
Since pests do not seem to be an issue, my first thoughts are the problem is related to some type of nutrient deficiency or shock from being moved outdoors permanently with increased sun. I have a pH meter - although I'm not 100% confident in it's accuracy - but it has read close to 7 throughout the plant's life. I have upped watering to twice a week as the plant now dries up after about 3 days in the sun. I do not think nutrient burn is a problem as I have been pretty cautious (originally, I had hoped to only use small amounts of Big Bloom when necessary as it's the only organic FF's product).
Feeding Schedule:
7/6 - 1 tsp Grow Big (after N deficiency, remedied)
7/13 - 1/2 Grow Big, 1 tsp Big Bloom
7/17 - Transplant to new location
7/18 - regular watering, no nutrients
---Problems appear---
7/23 - 1 tsp Big Bloom, 1/2 tsp Tiger Bloom
I checked out the plant last night and it seems to have stop spreading, but the effected leaves are slightly worse off.
P, K, Mg, Ca, sunburn, other stress?
Any help or advice would be much appreciated. Thank you!
Before last feeding, 7/20
7/25, two days after feeding. Problem seems to have stop spreading, but effected leaves are more damaged.
