Have not given an update in a while so thought I would get it done.

The young-un's have seemed to recover from the pH issue I suffered this past weekend. The new growth is very healthy looking. Today was the first true feeding they have received since last Friday's feeding, they were flushed heavily and have received only pH'ed water since the problem was discovered.
Here is a few pic's with headings.

I believe this is the damage from the pH problem, if I am incorrect please reply.


Same plant closeup


The group, the two on the left suffered the most from the pH issue.


They seem to have come out of the problem and are beginning to resume growth.

Prior to feeding I collected the liquid from the rez of each plant and checked the pH, it was 5.85, went in with 5.98.
Caught the rinsate from todays feeding and it was 5.95, went in with 5.98 pH'ed nutes. I have been using 3ml/gal of Cal/Mag but I increase that to 5ml/gal for a bit. Will see how things go.

Peace out,

u water everyday?
Every 1.5 to 2 days, hope to get to a solid two day once the plants take off well.
I have drained and watered The Hempy buckets daily since the pH problem with pH'ed rain water and Cal/Mag because the coco coir cap I put over the Hempy mix was not completely loaded prior to putting it on, that has been corrected I believe.
The pictures were taken right after the feeding today.

GD,

Thanks for the info.

Yes I would like to see his work, When you ask about watering I though you were talking about since I had the pH problem.
I have run Perlite/Vermiculite, straight Perlite, and a 50/50 Perlite/coco. In these grow I watered every day, or 1.5 days.
This grow is a 65/35 Perlite/coco. I was watering this grow daily until I ran into the pH problem that I created and after the big flush I did not water again until yesterday so that was two days after the flush, and that was just pH'ed rainwater, very low ppm, and 5 ml Cal/Mag/gal. Today I fed with 6 ml FloraMicro, 9 ml FloraBloom and 5 ml Cal/Mag. That is the Head take on the Lucas formula for coco. I use Cal/Mag instead of Epson. I will start back with every other day nute then pH'ed water on the off days.
I like this mix ratio, I used it in the Afghan grow last grow, fucker turn out to be a male, but I got really gr8 growth out of it. I am hoping this problem is resolved and I will see that type of growth with this grow.

Again, thanks for the help,

Peace out,
GR

Ps, If your interested in Head's formula you can find it here at http://lucasformula.com/ It is in the section on coco grows.

two stage vent your tent and you could use a weaker fan to vent the cab..
you wouldnt need anything more then 80 cfm if u did
you would still need proper ventilation for the light.

to be honest you wouldnt even need 80 cfm to vent tent you would only need 27 for proper ventilation

awesome, yea i use a 126cfm to cool my light a 400w hps and a 25 cfm fan to vent cab, both are pc fans, passive intakes, and it gets up to 13-14 sometimes 15 degrees F above room temperature
yes in the summer it can get hot hot if its above 80-90 but feed well and supply co2 and they will thrive... i just fed well and i did okay

Gotcha !! Also I have to take in account that the room my tent will be in the ambient low temp is around 38° possibly lower on some nights as it's winter here
yea same here, i dont like that, only good thing i see out of lows that low is more watts, but besides that its not good at all!
my tent is much smaller then yours (1.5d x 3w x 5 h in feet) 620w or a 400 hps and 4 55w t5's in a fixture that is factory air cooled, but with that space you have everything should even out...
