Hello everyone, im having a bit of an issue.
at first i thought it was a Zn deficiency but now im stumped. Im hoping someone might shed some insight on the problem.
My older plants seem to be yellowing all over and the leaves vein areas are turning necrotic, starting at the leaf-node. My younger plants (about 4 weeks younger) are all fine and green (aside from some slight nute burn).
I would say around 70% of my modest crop has turned and its starting to get serious.
Ive been using Technafloras "recipe for success", which is bullshit by the way.
Nutrient info -> http://www.technaflora.com/products.php?product=11
Using tap water PH'd to 6.8-7.
80% Fox Farms Ocean Soil / 20% perlite in 6" pots.
1000w enclosed HPS, 18-20 inches from top of plants.
they started to develop yellow leaves near the top so my first guess was N deficiency, then Zn, but BC Grow contains N and Zn and it didnt help.
I then tried Schultz Liquid Plant Food 10-15-10 http://www.schultz.com/NR/exeres/537...8181668714.htm which contains twice as much Zn but still no luck. Ive tried no nutes for a week. Ive also tried putting nails in water and letting them rust for the iron. Ive switched to a 2 day watering cycle. still yellow, leaves still dieing.
Here is a young one beside an older one:

Could they be outgrowing the 6" pots and thats why its only the older ones that are dieing?
I never intended for them to get this big in these pots but i had to put off flowering for a month or two.
heres some newer ones.
