need help with plant problem

hey, everybody. i'm getting real fed up with my plant. i have no idea what's wrong with it. someone on the forum convinced me it was a nutrient deficiency so i lightly fed it some nutes (3 mL/2 gallons of water [i have no idea how that converts]). anyway, after i fed the plant, it looks a little worse. someone then convinced me it was nutrient burn, so i stopped feeding it. anyone have any pretty definitive answers to this?

the first picture is the top of the plant.
the second picture is of the entire plant.
the third picture is a picture of one of the lower fan leaves (paler and yellower in reality).

whatever the plight, it seems to be striking the oldest and newest growth.

someone also suggested magnesium deficiency.

just flush with the right p.h'ed water and give it a few days. seems to be defishant in someting?

i flushed and i flushed. anyone else?

here's a closeup of a newly affected leaf.
is this nute burn or nute deficiency?

if the plant is indoors it might be ventalation (a fan) need more air circulating

no they're not indoors...

from the looks of the droopy leaves and the soil I'd say that plant is severely overwatered, causing everything to lockout.

but before I officially say that we need a lil more info on the plant.

how old is it? are U flowering? are U checking the pH of the water using a meter? what type of nutes are U using? NPK? how often are U feeding? how much are U feeding?

the plant's roughly 6-8 weeks old. forgot. lol.
it's still in veg.
the ph of the water is about 6.5.
i'm using power plant @ 3-1-4 at about 3mL per 2L of water.

...about once a week.

I know I`m the new guy , but looks like a trace element problem.
Boron to be more specific.A boron def will make your new growth turn brown and gray then it dies. B def. looks like your plants are to close to the light if indoors...which your not
Boric acid...which is sold at any drug store as an eyewash... will corect the problem.
1/4 teaspoon to a qt of water, it can take a few day`s to recover , you`ll see new growth coming.
Hope this helps ya some.
