Hi everybody,
This is my first grow ever.....(!)
It's a White Russian, 5 weeks, in a 3 gallon container with a mix of 33% vermiculite, 33% potting soil ( already pre-fertilized for 3 weeks) and 33% topsoil from my garden.
I gave it 24H light; in my garden during the day, and three LEDS of 75W equivalence during the night.
7 days ago there were 4 days of very bad weather with summer shower rains and cold temps ( around 18 degrees celsius) and they stayed in the garden during all this time, as there was no one to take them inside the house.
It's when i started having problems:
Tiny brown spots started appearing on the middle leaves, looking like calcium deficiency:
Here's a close-up:
Then the color of the leaves went darker, and their tips started to dip:
I have too bugs of all sorts starting appearing at the same time: leaf miners on the very bottom leaves
Here's a close-up:
I think on this image, both the calcium deficit and the leaf-miner show themselves.
Then i have another problem: tiny white spots on one of the middle leaves:
Yet, I can't see any bugs crawling on my leaves.
A close-up seems to show, after many hours of head scratching by me, white mites ( tarsonemediae) which is very bad news...
The new shoots at the top seem healthy:
But in a close-up, one can see tiny holes already appearing:
Other middle leaves are showing the same tiny holes, with no visible bugs:
Here's a close-up:
Do my diagnosis stand ?
The PH of my soil is between 6.20 and 6.70, which seems perfect.(measured with a digital PH meter on moist soil)
I did not give them any fertilizer at all until now, as i hoped the soil mix i prepared would suffice.
My tap water is 150 ppm, and i always adjust the PH to 7.
Neem oil, pyrethrum to control the pests ?
Thanks for your help and patience with a first grower.
