Hi all just to give you the rundown i'm using a flood an drain system with rockwell slabs and some grodan grocubes
i've been flooding for an hour with a half hour dry time between floods
I have a 55 gallon drum for a rez and it takes this long to fill and then drain.....without cavitating the drain pump.
my plants are 2 1/2 months old and on average are a foot tall and have been stem pinching the entire time they are mostly clones from a medi-bud plant from marijuanaseedsnl.com .......... and i have a couple other strains ....some arjanshaze #1 feminized from greenhouse seeds .....northernlights x elnino skunk feminized, white widow from g13 labs .........a pure affy strain from marijuanaseeds.nl...........
i've got a 3' x 6' area enclosed in panda plastic to the ceiling ..........top half for cloning and veg .......... bottom half for budding
using 2 250 watt hps and 1 400 watt hps in a home made cooltube...temps are right at 80 at canopy level which is about 16" off the floor..........outdoor temps are 79........I'm blowing air straight off an airconditioner through my cooltube by way of a diy manifold
plant spacing is tight i've got 54 plants in there 3 plants per sq ft and many tops on them some with five tops from the cutting stage
i've been using gh's 3 part nuts .....gro, micro, bloom
just bumped up to 1130 ppm veg formula (321)--(gro-mic-bloom)
the plants are looking fantastic (at first they were in shock because i used nutes on them too soon) but when i put them in the slabs and got the hydro going and they were in a good vegetative state I've noticed some rust...........it's only been a few days since i first noticed it and it's only on like 2 or 3 plants ...............and no it doesn't seem to be strain specific as it is on more than one type of plant.....................................after looking at some pictures on this site

there is no doubt that it is a calcium deficiency (at least in my mind)
and NO i cant show you pictures ........................you're just going to have to trust me that this is a calcium defeciency.....................I've been reading quite a bit lately and there's other post's about gh's 3 part nut's and people being calcium defecient
and the pictures on that post are exactly like mine and they are not ones that resemble any other symptom.............. like so many others do ......they are pretty much exclusive from what i can see
what i found to fix the problem is a liquid concentrate (and this the name)
NATURAL LIME...by RAINGROW
then it says
GET A LAWN for green lawns and gardens
it is a liquid suspended calcium and magnesium fertilizer that i think should work for my problem ........................my problem is that i don't know how much to add to my rez ..............
Ive been thinking that i would add it gradually to my rez until i raised the ppm 100 points...........................and see what happens
any thoughts ???????
the broke down gauranteed analysis is as follows
total calcium (Ca)........................................7.0%
Calcium Carbonate(CaCO3).......................17.0 %
Calcium Oxide (CaCO)................................9.8%
Total Magnesium (Mg)..................................4.0 %
magnesium carbonate (MgCO3)..................14.0 %
magnesium oxide (MgCO)............................6.7 %
Calcium Carbonate Equivalent (CCE)...............22.0%
Relative Neutralizing Value (RNV) ...................22.0%
Total Neutralizing Value (TNV) ......................22.0%
Solids.......................................................30.0%
derived from Dolimitic Limestone
Density .............1.5 kg/l (9.63 LB/gal)
I realize that this is going to effect my ph (not sure which way) which has been....... at least according to only fish tank tester drop's type and only goes down to 6.0...........so i've been keeping it at 6 according to that type of tester..........Along that note I have a digital ph tester but have no calibration solutions .....and i've read on this site somewhere that using evian bottled water has a certain ph value and that you could use that to calibrate your meter in a pinch ......... if there is any one out there that can verify this i would be very appreciative
please answer quick if this isn't a good idea and i might be adding too much
or for any other input for that matter
thanks in advance
