LOL

Thanks for the info. I already decided to go with the EC is additive approach. I'm 90% sure that the burn issue I've been having is high chloride levels. Flushing seems like an easier and cheaper approach than RO for now.

Wow........

What he said. Try and mix it in. Or add a little soil with the lime next time.

Gnatrol, Azamax, Mosquito bits, sand or gnat nix top dressing - there are tons of solutions. Fungus gnats usually indicates that the soil/medium is too wet. If it's just a single plant, you can direct a small desk fan (~3-4" fan) across the soil and that will kill them off in a few days.

My tap comes in around 8ph and I just add nutes and it drops to ~6ph.

Are the plants healthy and vibrant? If so, I'd spray just about anything on them during lights on. Neem and Rosemary are good preventatives for both bugs and fungus problems. Weak plants or plants that are under attack, suffering lock out, etc - then I'd spray lights out.

I don't accept the premise that spending more equates to better quality or that cheap means my equipment will be outdated and/or broken in a couple (2?) years. For example, I still have working 2nd Gen Lumtek Ballasts - over 10 years old (before dimming and super lumens) - they'll still fire a...

Don't boil your concoction. Use an airstone.

You're right, they are advertising IR - missed that the first time.

My guess is you have mites outside the grow that are getting in. I had that problem for a few years, some flowers in my yard were just infested with mites and eventually they'd make their way into the grow. You need to take some proactive/preventative measures. Ie treat with neem every couple...

I like Great White.

PGR depends on the PGR - ie must of us would say stay away from Paclobutrazol. Others aren't aren't as scarey. I like Nitrozyme and DynaGro Foliar (or Grow) for foliar sprays, but it also depends on why you're spraying. If I have a CalMg deficiecy, then I spray Calmg. If I'm dealing with...

I don't see any infrared diodes. If you're lighting a single ~3ft tall plant that light would probably be fine.

It's not that simple. You should flush when you overfertilize and create a salt build up in the soil/medium. Otherwise there is no need to flush. Plants use nutes until you cut them down, so there is no real need to flush at all.

If you think you have lock out or on the verge of lock out/toxicity, then I'd flush, otherwise the plant needs nutes. In your case, you're way off, so I'd probably be feeding those plants. I'd say you have at least 3 weeks to go and probably much longer.

Yeah, but that's so easy to deal with. Chlormide is a bit more difficult. Wouldn't be a big deal except setting up an RO where there is no plumbing isn't a realistic option. That said, I'm just going to step up how often I flush/leach and I'm sure I'll see an improvement. I used to...

I had good luck with Shenzen Umol.

I tend to agree.
