Hi bibbles, sorry about all the troubles your having with this batch, we've all been there
Hopefully next go around will be problem free. One thought I had is that from all the research I've done, there is a significant difference between using the 3% H2O2 that you get at CVS and the food grade 35% H2O2 which is really what we should all be using. They add all kinds of stabilizers to the 3% stuff that can bind to roots and even cause lockout in some cases. You may have no problems using it, and the food grade stuff is hard to come by, but if you can get it, I think it's worth it. It's a watched chemical though so have your grow shop order it for you. It's great for oxygenating roots as well as keeping mold/bacteria/fungus away. Also you could try some home made Clear-Rez which is just HTC brand pool shock powder sold at any True Value, mixed at about a tsp to a pint or quart of water depending on the desired concentration. Put a few tsp of this mixture into the rez to kill nasties. Has worked well for me. I had a terrible white slime infection on my clones, and I had violent downward pH drift as a result. I had to throw the clones out but I ran a high dose of shock through my cloner for a few days, cleaned it and am starting over. The pH is stable and the infection seems to be gone. I don't know if either of these suggestions have any appeal to you but it's all I can think of. Oh and you might want to look into Myco-Grow which is a special formula of beneficial microorganisms sold by Fungi Perfecti. There's a big thread on it here:

How are you liking the Inda-Gro? I am considering getting one and can't decide between that and an LED like the Pro Grow or maybe the 357 Magnum Plus. The Inda-Gro is a bit cheaper than the others and also has a full spectrum which I have come to believe may actually be beneficial as opposed to LED which just targets a few specific wavelengths. There's very little independent info on the Inda-Gro and even fewer journals; yours being one of 2 that I have found. So what's your opinion of the light? Is it comparable to a 600W HPS or even a 1000W in terms of yield and quality? Should I pull the trigger on one?
Honestly, it just got to the point where I decided to use this as a trial by fire, so that I would be able to avoid them next round, and trying to keep things on point seemed better that trying to treat symptoms. I'm harvesting tomorrow, and honestly, as things look now, it was totally worth finishing out. I know I fail at posting pictures, but running my lights at night ended up clashing badly with my schedule, so what little time I have has been spent caring for the garden, rather than talking about it. Next round they will run during the day, as apparently there is no peak/off charge difference, and I think I might actually save power as my A/C will just turn off at night with no heat sources to cool, rather than running to cool the sun, and then running to cool the lights. Did some math, it should run at 150% during the day, but only 10% at night, so I should save 20% on the power for the A/C, and either way, I'll be able to take better care of things.
I was using 10% h2o2 from the hydro store, and it seemed like it would kill off everything, both good and bad, and then the bad would come back unchallenged. The h2o2 flush followed by tea was good. Come Monday I should have new plants hitting the system, and I'm currently brewing a tea composed of Progress Earth's Inoculate (gave up looking for castings, and this is what was used in the tea I bought, which worked very well), Seaplex, Earth Tonic, Molasses, and MycoGrow Soluble. It probably costs a bit more than the tea mentioned in that thread, but since I'm using it in a clean res, so there are no sad roots or anything to eat, and aero, so there's no soil, etc... I figured the extra food for the little guys was probably a good move, and a few more trace nutrients for the plants won't hurt.
H2o2 doesn't kill all the bad guys, but it does kill all the good guys, so... this seemed like a better option, and in the long run, shouldn't be too much more.
As for the induction lights, color me impressed as hell. The 400W light was good, but these 420W lights are something else. Lower buds are equally mature to the top, albeit a bit smaller. Given all the problems I've crashed into, I think harvest will still be more than acceptable (that's all I'm willing to say, don't count your eggs, etc., etc.). Something most people overlook with LED lighting is that... with most, you can only light the area directly below them, as they use focused lenses to get the most out of their LEDs (read: artificially inflate ratings), and while the induction lights still won't give you the versatility of whatever-the-fuck-reflector-you-want, they do cover 4x4 very well. I haven't used LED, but after about three months of researching, my final decision didn't even involve LEDs. The only really successful uses I've seen end up using more power than induction, and producing more heat, while lighting a smaller area.
Honestly, the only think I neglected to weigh when I was looking into them, was the fact that it's significantly easier to see your plants, or any bugs, etc, etc... as the light isn't orange/purple, it's like being outside. I bought the 400W light, used it through two grows, and went back for more - the second time they had 420W lights, grabbed two, and... I'll probably replace my current 400W with another 420W when I'm done with the so far absent vertical ScroG. The 400 didn't have the same effect on the bottom buds, but should be just as good with a flat canopy, as there won't be any bottom buds.
So, I would recommend them, but I would also recommend that you balance everything before you make a choice, take into account the heat each generates, how that will effect your room, can they be mounted on a light mover, how much do they weigh (if using a tent), do you have an A/C, or have you just been relying on cool tubes, etc, etc... for my garden, I wouldn't make any other choice, but your garden is your garden, so step away from the light science for a moment, and remember that everything has to work together (if you haven't already).
Also, the delivery box WILL say "Agricultural Induction Lighting" on the outside, in fairly obvious lettering, if that's an issue. I mentioned that to them when I got the 400W, but I can easily see people not buying them because... I've heard stories about people trying to explain away questions when boxes showed a filter or something, but there wouldn't be questions, other than perhaps WHAT you were growing... so, just keep that in mind.
PS. Clearly I haven't been posting because I have nothing to say, lol, just grinding way too hard. Cleaning everything outside the tent today for harvest tomorrow, run with bleach after harvest tomorrow night, wash out in the morning, pick up clones, and hopefully have them in by lights out, if not, I'll give them one day of veg, but these clones are suppose to be ~12" now, so... that's more than tall enough.
EDIT: Also, of course, ignore lumen ratings, as your plants are not made of eye-balls. :/
