Leaves Drying from the bottom Up, HELP!

Banadoura · April 13, 2018

I have an issue that is mind boggling, the plants I seeded a month ago have gotten to a point where the bottom leaves dry up and fall before the whole plant starts curling on itself.

Here's how it starts:
Notice how the dryness spreads from the leaf to the whole branch.

the dried leaves crunch between your fingers....

Then this is happening (at least with my Whiskey Jack variety)

I don't think my WJ plants will survive long enough to get planted outside....

I'd like to believe that my plants are comfy in their container, get fed with the blue sutff and in theory have enough light thanks to two T5 bulbs but the reality says otherwise, something is wrong!

Theory number 1: could it be my T5 bulbs?
Today I read that there should be at least 4 inch between the plants and the light, my plants were closer than that but that does not explain the problem starting from the bottom.

Theory number 2: Excess fertilizer? I am using the all purpose blue stuff that you dilute in water. I read that the feeding should be spaced at 2 weeks. My plants get on a average 1 feeding per week. Could it be that there's too much N?

Theory number 3: UV burn? Behind the curtain there's a window, could the UV rays be burning those leaves? a little bit far fetched?

Theory number 4: Would not having a fan trigger something!?

What do you think?

Thanks
