Leaf problem

What is the source of your tap water (well, city, other)?
Those plants look excellent to me. You perfectionists, lol.[/QUOTE]

out in the sticks ec out of the tap 0.63 slightly hard, as for the light running out of room about 2 inches left to move it up. I think i might be in the shit with that.

how much more do you think they will grow up
Thanks for the compliment :rasta:

Well since you're out in da stix we don't really know what is the major contributor to the hardness of your water but whatever, really your plants are fine, lol... except that you're out of room in early flower! Uh oh spaghettios.
Plants often fully double in height from inception of flower to harvest time. I don't know about your individual plant but you may want to plan for a taller space to move into if you run out. eek!

Eek indeed, my grow box is 2 meters tall and the light is at the top there's no room left, what's the worst that can happen? :rasta:

Now is a time to work on prevention of future problems: Have you tried doing a comparison of the pH/EC going INTO the coco vs the pH and EC coming OUT of the coco? I'd check those numbers. If the 'out' EC number is equal to or higher than the 'in' number, you have cause for concern.

I checked my tank and it was sat at 1.71 ec and 5.9 ph .
so i lowered the ph to 5.6
watered plants about 30% runoff and the ph came out at 5.6, ec came out at 1.74 .
what should i do stinky ? :rasta:

[stinkyattic]

I'd pour some plain pH-adjusted water through the pots by hand (=flush), discard the runoff, refill the res with your bloom nute, and continue flowering.

[gamdwtj]

Nice one, i'll get on and do that.
i lowered the ec to 1.56 yesterday and ph stayed 5.6 watered the ladies for a 40% runoff and the ec came out at 1.58 ph 5.7 . Is this a bad thing and why has this happened? :rasta:

If you go to the Canna website and read all of their propaganda about coco coir and coco nutes, somewhere in there you will find a statement to the effect that coco runoff is not a good indicator of anything significant. I suppose if your runoff was way acidic or way alkaline it would be cause for concern, but trying to micro-manage your nutes vis-a-vis the runoff apparently won't work with coco.

PC :smokin:

And actually .02 difference in the EC of the runoff isn't even significant- betcha that's actually within the instrument's margin of error.
PC, I didn't know that about coco. I did know that coco scavenges Ca and releases K, so the mineral contributions to EC might be a little screwy, but that's an interesting tidbit. What an odd medium.

[gamdwtj]

Thanks pc not alot of people know the in's and out's of coco looks like i better do some reading. few pics of what they look like now. :rasta:

listen the leaves lookes nutrient burned to me so i would just use plain water for a while...it happened to me the leaves where getting fucked so i stopped with the nutes for a while and everything was all right after about 2 weeks the plant was healthy again!
