AAARRRGGH!! Zandor/Latewood Need new help PLZ

I don't know if this should be in a new thread, but didn't seem to be getting any response with the new post on the last thread. I have an issue with these two and am, quite honestly getting a little confused. I have been through every possible page I can find on Overgrow, and many 100's of threads here. Symptoms seem to be mimmiking deficiencies, N or FE according to Jackerspakle, and the pics he or they have posted seem to verify that line of thinking....however, I also found a section that says that it could quite possibly be the light, or amount of light the grow tips or bud sites are recieving. This also makes sense with the kind of pattern that is taking place. Here is everything about this grow if you could offer a little advise. The farther out from the direct light source each tip is the darker and healthier they appear to be.

*Bag Seed...8 planted / 6 females / 3 kept for Bonsai Mums
*6-7 mos old TTL...approx. 21 days into 12/12
*cabinet set-up...265cfm / 150w HPS in cooling hood (see pics)
*6" Pots / originally filled with MG PotMix (didn't know any better then)
*SCROG above
*Temp Ranges...75-78f always
*Pests?...a few Gnats occassionaly, but get sucked out mostly
*Nutes.....
Schultz Liquid Plant Food (10-15-10)
Schultz Orchid Food (19-31-17) powder / water soluable
Superthrive (as-is) 1 drop per 2qt water
MG Bloom Booster (10-52-10) used yesterday ONLY
*R.O. Water.....stays at or near 6.5 - 6.7 Ph (initially)
*Watered & fed Daily / currently....plants take 2-3 pints each daily before
water runs out bottom of pot.
*General Feeding Schedule.....daily with watering at 7 drops for every Two
quarts w/ 1 drop superthrive
used MG Bloom Boost once only to see results, changed back to
Orchid Food Today, will go back to Schultz LF from here on.
Ordered FloraNova three and 1/2 weeks ago...and, my luck, it ended up at UPS in New Orleans the day before the disaster....who know when I will get it...so am trying to get by until then.
If you need more info, let know and it will be done !
Thanks Again for your patience with this newbie.

Are you taking about the light green one in the middle?

If all you can get for nutrients is shuts you should be using the cactus version it's closer to a resin plant then orchid's are.

If it is what I think it is, you won't believe me...

There was this system that ran 4 600 watt bulbs over a 4 foot x 4 foot area. Andthe lights were kept at about 4 - 8 inches from the tops of the plants.

Well the tops of the plants lost all their pigment..

IT WAS TO MUCH LIGHT!! This happens to plants at HIGH elevations that are closer to the sun.... It supposedly is just to many damn lumens and the tops of the plants turn yellow/white. They don't die or suffer any necrosis. If you pull the light away even an inch, the plants get their color back.. see how the plant in the middle that is closest to the light is the lightest... that's what clued me in...

Now the problem with this theory is that you are only using a 150 watt bulb...
go figure.. just my 2 cents...


I took a close look at the pics...do I see red stems? You can take some of your soil and stir in water .. let it soak for a couple hours and use a PPM meter on the water...
I think this works... and you can find out your soils ph too...

Here are a few more pics of individual sites and the overall pic again labeled to identify where pics came from. I am just scared that I will end up with the same little bitty buds (rosettes?) that I ended up with last time. Only got a couple of really nice ones and they were so good that I can't bring myself to buy commercial crap even when out.....ya know?! Anyway, I have moved the light up another several inches (watching for stretch) but so far doesn't seem to have affected them any...

Thanks Again for the help
Will go get cactus food today. :)

Does it ever end???....I guess that if I intend on learning, I gotta have problems to learn from. I moved the light up about another 3" to try to stop the yellow leaves. NOW, I have red or rust colored areas starting to show up between the veins on the leaves. I can only assume that it is being cuased by nute issues, have only given the bloom boost once, and then back to schultz liquid food, then for the past several days, have been feeding with every water, schultz cactus liquid food, and superthrive. red started about two (2) days ago, and has grown worse since. Any suggestions or comments would be greatly appreciated. Here are a few pics, will post more shortly as the HPS lighting doesn't allow the color to show up correctly, will have to light the plant differently for the remaining pics.
OOPS...forgot to add this comment. These pics are of Sativa site 1 & Indica Site 2 from previous pic posted.
