This is my first grow and my first post-- which I hate writing because I prefer answers through research rather than hand-outs, but here I am, truly and humbly stumped.
There are five plants, two are WW and three are bag. Each strain is showing a unique set of symptoms.
Symptoms manifested early in the grow for each... older leaves yellowing for both, then the WW start to curl upward and die from the tips inward. The bag plant older leaves would grow increasingly yellow and get brown spots uniformly across the affected leaves.
I smartened up and got a PH meter, which showed 5.5. After a lot of reading and trips to the spa store, I decided on wood ash (1/4 teaspoon per gallon) to bring it up. It's held steady at 6.8ish without further treatment.
The problem continued.
After a lot more reading and comparing my leaves to pictures on the "sick plants" page, I figured it was a magnesium deficiency. I treated with epsom salt (1/4 tsp per gallon) for one watering.
The mag treatment was 6 days ago and the problem continues.
Two days ago I transplanted all from 1 gallon to 5 gallon pots.
THere aren't any signs of pests. Though I admit I haven't bought a magnifying glass yet.
Soil Mix:
5 gallon
1 part perlite
2 parts Scott's potting soil
1 part Miracle Grow Organic soil mix
1 fistfull of bloodmeal
1 fistfull of bonemeal
Every third watering I use fish emulsion tea.
Twice I've used a 200ppm 8-16-8 fert. (Monty's Joy Juice)
I'm growing under a 430 watt HPS about 2 feet from plant tops.
Temp varies from 75-80 at mid plant level. Humidy is dry, usually around 40%.
Please help me diagnose these problems.
