[stewie420]

Oh wow your good

this is EXACTLY what i thought when it was the first
set of leaves then the second, but now its reaching
the 5th out of eleven nodes and hurting the bottom
secondary growth... which royally pisses me off, since
it seems to be doing well in that area...

[HARDDON]

i gave the fern a heathly flush and watered with the
new food... !!!

WTF?

Dude do you want to save or kill your plant?

I know its a rhetorical question...but.......

Pick someone to listen to and listen to them.

Kinda like a sorority brother

Looks to me like normal aging of first leaves to me. The shoots look good and healthy.

Fan leaves will all die....especially the lower ones.

I follow the rules that say nute probs and other chemistry issues start at top.... and work their way down.

Those leaves just look like they are old and giving way to a lot of secondary spaces.

Those leaves are not that old. That is not normal. The most common reason the lower fan leaves dry up and turn yellow or fall off that early is not enough light and that stops the leaf from producing chlorophyll. I don't know if that is the case here I don't see how close his light is or what type of lights they are under or even the average temperature.

So I say flush and be safe. When you start feeding nutrients again start with 1/2 strength the first time back then bump it up.

Not familiar with Nitrozyme. Sounds like an addition of enzymes that promote root uptake. You'll have to read the label, but any pure liquid form of N will due, but I prefer all organic sources.

nitrozyme is just a nitrogen booster... so it sounds like its the same
stuff...

HARDON... i dont mean to be ignorant, but i thought the flush
was to get any of the nasties out of the soil and then i should
feed them to get them healthy again... ive seen your grow log
and from what i saw you sure look like youve got a good handle
on growing...

at any rate... the plant is still alive, the new growth is good, im
just waiting to make sure the yellowing has ceased, which i suppose
wouldnt happen in one night if the nutes were indeed the problem...

ill give them another 2 days, so long as things dont get any worse, and
ill go from there...

zandor... my setup consists of a standalone 3x4x8 closet fully mylard...
ive got a 150 HPS hanging about 15 inches over the plants... there are
2 in the closet... the sick one and sort of a midget plant...

ive also got 4 28" cool white tubes against the back of the closet and 2 sets of 2 foot cool white tubes, one on each side of the plants for vertical light.

ive got a fan on pointed towards the top of the plants which is aimed so
that it cools the HPS light... it doesnt get too hot in there... the leaves
dont really curl on me or anything...

thanks!!! i need to smoke a fern...

by the way... anyone ever order from the great canadian seed company...
cause ive been waiting 4 weeks for a delivery and have got nothing... ???
im gonna email them right now, but i was wondering if anyone had any
experience with this company... thanks!
