For cleaning glass, along with rubbing alcohol and coarse salt, some dry white rice helps too. 90% alcohol works a little better than 70%.
Yes it does, and studies of 99.9-percent isopropyl alc indicate that an opened bottle will lose 7 percent of its strength over 15 minutes.
So basically, buy the pure stuff, combine with salt, and don't leave the bottle open too long.

ISO is very hydroscopic. It pulls moisture from the air.
If you take some drug store IPA, pour it on a mirror and let evaporate, there is generally a film left behind. Keep that in mind if using IPA for cannabis extracts. I think it is just minerals or whatever.

I'm needing to drop the ph of my coco coir(hydro), it's sitting around 7.3.. been watering with 5.6 ph'd water, will watering with a lower ph like 4.5 cause problems? been struggling to get my medium ph down, since my ph meter shit out on me a few weeks ago.. I feel like I've been having nothing but problems this grow

Don’t do that, it will shock them. Just keep it between 5.5-6.3 and you will be fine… look into fertigaton…..
I’d start with a light feed at around 800ppm 6.0 phthen after a couple feedings like that drop to 5.8.

thanks man... I've been trying to keep my ph within those ranges, next go round I'll be more attentive when it comes to ph and ppm... pretty sure the chart I was following had me running on the high end of feeding 1600-1850ppm... got to reading marijuana horticulture by jorge cervantes and it said to try to keep ppm's between 800-1200ppm when feeding

You have to build up to those ppms, those are for big full size plants… Some people only feed 1/4 strength nutrients in coco all the way through… I don’t do that, I beg em up and give them what they can handle and tweak it til they’re happy. That’s why it’s kinda hard to grow several strains at once getting fed all the same. Some like different ratios, some are nitrogen hungry like some purps or some don’t want very much nitrogen at all.
You got it. You can always hit me up if you need help with growing in coco…

If it does get to high you can go low to equal it out. That's the way I was taught.

It's not just about measuring the input ppm, you gotta measure the runoff too. If the pH has crept out of range, there's a chance the ppm's have been climbing too. If you have an undiagnosed ppm issue, lowering the pH isn't going to be so effective if the plant has essentially closed its mouth (roots) to avoid choking on too much nutrients.
And in theory, correcting the pH by feeding even lower makes sense, but I think there's some reasons not to. Otherwise why not drop like 6 drops of hcl in a liter and feed them at 1.2 pH yaknow? I think it'll be better to flush them with tap/distilled/RO until neutral and then feed at the proper pH. That's part of the reason why I think your ppm must be high if your feeding input isn't having much effect. For example there could be 5x more ppm in the pot than what you're feeding at, so the feed pH is only having a fifth of the expected impact. If you flush all that ppm out, then the media can be immediately set to the next input pH.

For some reason I’ve only had two plants that could take 500+ ppm. I typically max it at 350-400 and they do great. I gave up trying to figure out why since it’s basically seedling level feed for most people.

It’s way easier to flush coco than it is soil… it’s best to just flush and start keeping an eye on the ph…for coco that is…

If I had a auto watering system I would be more likely to use coco. I've ran one pot in coco only and it turnt out pretty decent.

The stuff I get here is pure, no film. But it's not drugstore bought, it's an online solvent store.

I've been measuring everything... ec is low, ppm of runoff wasn't high only like 400ppm, just the ph of runoff is high... I'm pretty sure it's from my ph meter shitting out on mea couple weeks ago... I will keep trying to lower ph slowly over the next week or so, I've got Chemdog & skywalker og in the tent if that helps... they don't look bad or anything, just not in the ideal ph range

Lowered the light from 36in to 21in from plants. Power is 40-50% Mars hydro says 12in from plants. That seems close. The blog says give 6in space from what the guide says.

Plants look better. They was droopy day of transplant. Soil still got enough moisture. Maybe water tomorrow.
I am using growdots and they are slow release. One time feed for whole grow. Plus I'm using recharge once a week in the water.
