Do you use an Ozone generator? Because it looks either like that or you're over fertilizing. Whats your fert schedule like?

Hey thanks for the reply...No OZone Gen...VERY light fert...plant is about
2-1/2 feet tall. after research and googling i'm thinkin' cal def!? I foliar sprayed w/ some crushed lime and eggshell powder solution ...? Possible visual improvment!? (I dunno?) gonna give it 24 hrs, then maybe some Epsom salt solution?
def NO Bugs...and quality GH products Only!
Still don't know it's gender either..('nother few days) .so if it's a boy I'll just dump it! Thanks for the help...if you think of something other, IM me...peace

What's your ph? Not familiar with spag moss so maybe its something that shows with it? Too many variables..

It doesn't look like a cal def to me but the tips are bent so it could be a bit of a mg def...either way, epsom is a good fix for that but it could all be caused by ph. A good place to start looking anyway. What strain are you growing?

Good luck!

It takes longer that 24 hrs for corrections to show. Think more like 3, 4 days.

Hi Jenna_G's...
PH= 6.8
Spag= Spag Moss/Spanish Moss-kinda similar to a coco coir...
(it is inert and airy nothing like Peat moss) - it is PH buffered
I am using a touch of CalMag plus...!?
The strain on this particular plant is an unknown bag seed, however during Veg, the larger fan leaves measured 1 1/2 inches across. prolly a Indica/Sativa 60/40. It seemed to start at 12/12 cycle, when I intro-ed BigBloom!?...it almost appears to be somewhat necrotic in a way, but like I said only the older larger fan leaves in the middle of the plant seem to be affected!? (your help is most appreciated Jen ;>))

The only other thing I can think of is maybe an Iron deficiency? Alot of these other things manifest in either the newest or oldest growth first, but you say its starting in the middle. Fe (iron) deficiency starts in the lower to middle growth, thats why I think maybe...

To much Fe without adding enough P can cause a P-deficiency, and likewise too much P locks out Fe.

Note that when adding iron to the solution, it is often necessary to not use fertilizer for that watering. Iron has a tendency of reacting with many of the components of fertilizer solutions, and will cause nutrient lockup to occur.

Chelated iron is most effective in plants (as opposed to putting say, rusty metal in the mix), looking at your fertilizer it may be labeled Iron EDTA.

Okay, thats it. Thats all I can think of. If none of that is it, I'll eat my shoes.

Sphagnum moss Jenna. It's ggod stuff, can hold a lot of water while remaining aerated. There are environmental concerns about its use as it is being harvested faster than it is growing back- that's one of the reasons coco coir is touted as the new thing..
Sphagnum moss is used to make peat moss.

chefyD- like Jenna says, pH would be the first thing I'd think about.
You can get an idea of soil pH by checking the run off and comparing it to the pH of the water or nute mix you used.

We use that shite. Or used to
The tips are turned a bit which shows a mag def but you have nuted for that.
Course the dead tips look like over-nuting.
Your Ph should be closer to 6 than 7 as it is an inert material. 6.8 is not allowing the plants to uptake at their full capacity, not really close.

The first thing I thought when Jenna showed me that pic was PH issues.

Thanks for the input and the facts about Spag, I only purchased a small amount just as an experiment. Headed to the Hydro guy today, gonna try working w/ the Coco coir...peace bra'

Jenna_Grows

I've been reading up on coco... it's more apt to show mg defs.. Something about Potassium being released as it dries. I was thinking this sphagum moss was similiar to the mix I just started using for an orchid.. its got chunks of bark, some moss, and a bit of peat. I wonder if it releases by-products as it dries.

New growth looks good..that's a good sign. Is it getting worse?

Make sure you rinse the coco before using it... rinses off the salt..

chefyD

Right on, headed out this AM to the hydro guy..I'll let you know...ttyl

chefyD

Hi Jenna, Things appear to hav stablized for now farmergiles said some peeps have had issues w/ FF products? It worked for me last time he said something about "Tiger Bloom" heade to hydro gut today....thanx for the solid input Jen...I'm liking this ship!

Dandaweedman

Must be nice to have a local hydro store. Ours went tits up a few years back.
I didn't rinse the coco the first time. DDWM, murderer.

Yeah man...actually it's kinda hard to beleive we have one now (last 12 months) My area is not up to the speed of 2011, more like 1776...LoL .
It is doing remarkably well, in fact they will open a new one shortly about mabey 65-70 mi from here.
Mine is about 15 mi or so, so about a fifteen minute drive!
11 AM till 6PM

I think foxfarm are supposed to be good, a lot of people seem to use them. I've never used them myself so I can't say for sure.
