cant do one of my normal LONG posts...

will edit later today

please post your thoughts

Ph pen was off (reading .4 high) so my hand watering nute was off until 2 days ago.
too soon to see improvement?






got to get to work but...
if the pen was reading high than the mix was low: I was aiming for 5.6 but it was 5.2...
but too low shouldn't have caused... IDK
like I said, thought/input appreciated

.

great idea!

edit:

phosphors

yup yup
just getting all my stuff together in one post

manganese and phosphors would account for the leaf damage (brown areas -and- "dead-dots")
and both would be locked out @ LOW pH

its always nice when things point in the same direction :)

going to water with 5.9 for a few days


for whatever reason, I was thinking my mix was too high so after recalibrating the pH pen (2 nights ago) I set my jug of nute @ 5.4 and filled'er up...
exactly the opposite of what I should have done but @ least it was higher than it was.

i ran a DWC and 6.2 ph was the magic number for me, anything high or lower, the plant looked poor. i experimented with high and lower ph to see what the plant would do.it didnt look right with anything below or above 6.2. dunno if you wanna go that high or not. it may not even work for you. i think its alot to do with nutes and temperature and such. my 2 cents

right on!
I'm all for personal experience posts
I was starting to think I noticed the pattern of more growth/stretch during my high pH times (drift through 5.5 - 6.0 usually)
-but-
I only have about 3gal of nute in my tote so it's not the same pH for more than 4 hours

water temps are kept around 66F
air temps with VEG lights are 77F on canopy height

this is xxxxx xxxing me off!!!!!!

I have 1 pH pen and 2 nutradip continuous

I've calibrated all 3 with 4.0 and 7.0

I'm mixing up 3 gal of nute in the tote, figured I'd check what distilled water is...

pen says 6.5
ND#1 says 5.9
ND#2 says 5.1

but I can pull the probes out and put them in the 4.0 and 7.0 and they are ALL (3) dead on... WTMF is going on?!

seriously NEED a few hits

So...what's ya puffing??

Oh and what's the drip system checker contraption you were mentioning before??

Is it like a cup that water flows thru with a needle?

From the resi?

Buildup ??

been hitting the white Siberian for the past week (since harvest)
so its about time to switch over to the critkush

still @ it 3:30am

some things learned
lots of frustration though

more to come
after sleep

.

continuous probes seem vulnerable to "motion" or "flow" of the probe through fluid or fluid over the probe.
it lowers the reading by up to .5 for up to 1.5 min

when the dots on the page don't seem to make a pattern, add more dots





"major" changes for this grow (so far) will/have been:
adding H2O2
plan to drift from 5.5 - 6.5

there she is, FINALLY bathing in 6.4 pH 650ppm 66F nute... I think

You have an awesome set of tools by the way...

.

hydro (synthetic) its A L L about the pH and ppm so I H A V E to know where it is.

I'll try to do a little pH pen roundup thread or something compare the 19.99 vs the 350.00 vs 60.00

I am interested to know...cause honestly use the yellow only cause I'm a cheap skate....and if it's cheaper and accurate?.

that was the first it was in the tote (about 24 ago now)
"she" was over in veg up till that point with no reflective surface under her
[edit: correction: it sat on-top of the tote for a day too]

I covered the top with flat black garbage bag

ty

this may be a dumb question. how often are you changing the water? i changed mine out every 7-10 days.

this plant has only been in a tote for two days
the current nute bath is 2 days old

I start with a full new mix every 2+ weeks (3 in veg... depending)
I add water and fresh nute mix during that time to keep pH/ppm "correct"

any/all damage to this plant occurred while I was hand watering it like a houseplant (4x4x4 rockwool cube in a netpot)
over in VEG.
I aerate about a gallon of light nute and hand water when the cube gets dry/light (to over saturation)
that mix was pH'd very LOW

My experience says you can hand water a 4x4 cube all you want no need to wait till it's dry or light....it's not soil and doesn't need to dry out for more air....just stresses the plant by not feeding regularly IMO

orly? cool!
independent of the aeration?
or can I skip that too?

edit

newest of new




PS
she still doesn't have her "sea legs" under her yet. as in -0- roots dangling beyond the netpot

When I have that look my nuts are too high....
