PICS!! what is wrong with my leaves?

[Frozenguy]

here are my specs-
3gal pots with coco.
4 romulan plants each about 4 feet tall. 2 600watt aircooled 10" away..
canna coco A+B at 17 ec (11ml/gal)
cannazym
dutch master silica
bot. SWEET
temps-85ish
ph is 5.8-6.0
running sealed/co2 enriched room.. temps can be lower and are sometime sbut on average about 83-85.. will be lower soon like 78-80.,.,

humitidy is about mid 30's during lights on and maybe as high as low 40's in dark..

sprayed D.M. foli tech grow through veg and folitech flower 2 weeks into 12/12
this is day 23 or so of 12/12..
here is a picture of somes leaves that were towards the bottom of this plant..



and this leaf is towards the top.. some go limish/yellow like this.. this is an advanced stage of this with the curling/drying/dying of the leaf..




any help would be great

 

[Frozenguy]

let me clear up that those two pictures are of two different problems.. the top picture is what slowly happens to some of the lower fan leaves that arn't recieving much light at all.. the bottom picture (completly yellow) is what happens to some of hte higher up fan leaves.. in full light. but still about 24" away from an aircooled 600 watt.. there are a few more leafs like that yellow one in different stages of that issue.. some plants have two, some have one, some have just some discolored leafs but not that bad..

I think it's probly normal. My Romulan is at just about 30 days, and has already dropped some of her older fan leaves. If this is what I think it is, then it is just the plant pulling the nutrients from the old leaves for her reproductive growth. If ya give her some veggie food it should help. Don't take this as gospel tho.(unless the smart ones back me up)

I don't suggest using nutrients sprayed onto the leaves. Once sprayed you can not get the nutrients back and is permanent. Ferts applied to the soil/reservoir are able to be flushed with straight water if there is excess nutrients. There is really no reason why the plants can't just get the nutrients through the roots. Foliar sprays are best reserved for when applying nutrients (especially micros) to the soil is not feasible.

i wouldnt foliar feed... im gonna say it looks like some n probs and a sulfur def.
i think...

ive used both the folitechs many times and never had them cause damage like that ,,
did u over spray them ? what time of day did u spray them ? i found just b4 lights on is best
i think your problem is over feeding in general ,your ec was to high ,,,if u foliar and root feed, the plants are getting huge amounts of nutes ,,u needed to lower nute levels and foliar applications when the leaves started showing deficencies/toxicities,,
next time u will notice and adjust accordingly

I probably should have been more clear.. folitech is a product from dutch master that increases the plants ability to proccesses 30% more light.. the plant doesn't actually use all the light that hits the leaves.. a lot bounces off and stuff.. this stuff allows the leaves to absorbe more light.. i'm not sure abou tthe difference in grow/flower but they are not nutes..
here is a shot of the main cola..
my plants havn't really been burned.. i burned them once when i pushed them to 1.8/1.9 EC and then i flushed and went back to 1.5/1.6 EC.. the burning stopped..and frankly, the plants kept the buring to the lower, popcorn buds.. didn't spread to the upper foliage..

my watering schedual is basically to water then wait till the top is dryed off a bit..its usually about 800 ML of water a day. sometimes i end up giving them more like 1000-1100 ML a day.. EACH btw.. these numbers are per plant..

here is a shot of hte main cola


EDIT: Folitech says that you can apply it (even mixed with pennatrator) with the lights on as normal.. but i always shut the lights off (except for a florescent or something) and spray them, let them dry off (like 10 min) then fire up their lights again.. is that bad?? that wont hermie them will it???

Who makes Folitech?

 

[Frozenguy]

dutchmaster makes folitech along with pennatrator.. pennatrator opens up the pores of the plant (stomatas?) and allows for greater absorbtion of foliar feeds..

 

[mace_ecam]

dutchmasters, the guys from south australia that brought out super bud, you know that carciogenic stuff, which they "forgot" to mention on the label and was therefore banned later ...

 

[Frozenguy]

lots of companies have had to pull stuff off the market.. doesn't mean all their shit is bad.. but that did run through my head a lot.. i'm gonna see what kind of difference this stuff makes..

 

[Guest]

btw the dutchmasters stuff works just as good without the superbud ,,ive just used the advanced and it too stopped stretching and made the buds denser ,,,folitech imo works very well especially the veg 1 when used with the max veg ,,combined they produce branching like you wouldnt believe

 

[Frozenguy]

so any ideas?
