The clones rooted and I put them in the table.
running about 300 ppm FoxFarms grow big until I see growth
then switching to Sensi Bloom 2 part w/ bud blood and big bug.
Im thinking about starting another room, would it be worth it to dedicate another room to vegging?? or flowering?

anyoneone think I should use H2o2? also how do I stop sudden fluctuations in PH, it goes from 5.6 to 6.5 in about 5 hours?

so far ive been adjusting the ph from about 6.4 to 5.6 everyday.... this is annoying
Ive been keeping the ppms at about 250, the water originally being 250 too.
Lost some, they just fell over and looked dead, I think root rot so I have cleaned everything with h2o2 solution
I havent noticed any growth yet but the bigger leaves are starting to yellow, does this mean its time to up the nutes?
any suggestions to what ppm's?
I have the flood cycle at every 2 hours.

Hey man...

As soon as they have roots, they go into my trays, which are kept at a constant 1400 ppm... I only have one res for multiple trays so from day one to harvest, mine have 1400 PPM....

and some of mine just do flop over and die...

H2O2 is NOT COMPATIBLE WITH ORGANICS...

It will kill everything...

So if you are not organic, it's ok to use otherwise, there are organic compatible pathogen controllers out there, like Hygrozyme...

everything looks good though... I still don;t like the net pots at all... but I am glad to see progress...

Cheers..!

Oh .. most nutes have a pH buffer in them to help stabilize the solution...

When you add nutes, I bet you will see less fluctuation...

Are your net pots exposed to any light on the outside, or are they under some kind of cover? Roots don't like light, as I've learned...

Also, has the hydroton you're using been properly conditioned before the clones were put in?

How long is the flood set for when you feed every two hours?

How large are your reservoirs ? If you combine them into one large one the ph will fluctuate a lot less. I was running a 4x4 table with 2 300L/hr pumps in a 45 gal res. with 25 gals of nutes and I only needed to adjust the ph every 2 days or so. Also I only flooded my table 2 times a day which was plenty, but I had about 15-20% coco in my hydroton, which Im sure helped hold moisture. Still I would probably cut down on your waterings to about 3-4 times a day, you may be over watering right now, which could cause root rot and the yellowing. Plants would look look heavy and little droopy if overwatering. I always add H2O2 at 10ml/ gal before adding gh nutes and are you aerating your reservoir? (this is clutch)

its a 35 gallon res with about 25 gallons of water in it
I have build a cover with panda plastic and holes for the net pots, just not in the pics
1400 PPM huh? sounds about right, I think I will up it to about 1000ppm
I only used the h2o2 to clean the tray and res. its not currently in the nute solution
15 mins every 2 hours

oh and Im using 2 part sensi bloom for flowering
and foxfarms growbig for veg... im sure both have ph buffers??
there is a airstone in the res on a small fishtank pump

Do you have any other pics of the hole set up ? What size are the pots?

Ah, much better than the scenario I was thinking.

they are starting to get thick, like wide as the pots now.
Haven't gained any height yet, think its time to drop the lights yet?
I havent decided how long I wanna veg them yet, now that Im down to 20, Im aiming for 20 ounce and a quarter buds. roughly a pound and a half.
Pics tommorrow
