Just ordered a TDS (ppm) meter; be here Saturday...

Thanks. I don't have a ppm meter, but can certainly get one. I use town water, and they publish their analysis, broken down by particular minerals. The sodium level is 62 ppm; nothing else comes close in terms of concentration (Sulfate: 2.2 ppm, Fluoride: 1.0 ppm are the next two). Does that...

It's Northern Lights (from Sensi seeds). The stems of the plant itself are green, the stems of the leaves are a red/purple.

...and they're in 7 gallon cloth containers, that probably have closer to 6 gallons of soil in them.

P.S. Runoff from today's watering: 6.11 for the "problem" plant; 6.29 for her sister. And this is my pH pen, which I am suspicious of:

Truly appreciate your help. First, the soil is mostly FoxFarm Ocean Forest. To be precise: 67% FFOF, 27% perlite, 6% vermiculite. I had assumed my water would be pH 7.0 or thereabouts; this morning I set out to answer all your pH questions and my first reading showed my water at 8.09. I...

I haven't been giving calcium or magnesium. I checked the pH yesterday and found that it was low -- 5.5 when I tested the runoff; 5.8 when I mixed some soil with water and tested that. That can't be good, and I'm going to work on bringing that up.

This was a surprise. I have two plants that have been treated exactly the same. One has been doing slightly better than the other all along, which I think is natural -- different individuals. Recently the one doing better developed what I think is a potassium deficiency (see...

I guess that's one vote for nutrient burn -- thanks. I have trouble believing it though -- they're in 7 gallon containers of Fox Farm Ocean Forest, cut significantly with perlite, and I fed no nutrients at all until they hit 2 months. Since then (about 3 1/2 weeks) I've fertilized more or less...

What do you think? Growing in soil; 3 1/2 weeks into flower. I recently started giving FF Big Bloom every other watering; could increase to every watering, or give a higher concentration.

Thanks; will do. Yeah, but then we grow a plant in it, water it, maybe fertilize...

Nope -- I'm not a Facebook user. There are Facebook pages you can see without having an account; I thought the RIU page was one of those (shouldn't it be?).

Trying again; the link is: https://www.facebook.com/591230844307200

Thanks. But when I click on that it sends me to a facebook page that ends in 591230844307200 (begins with the usual facebook prefix -- RIU seems to think I'm not permitted to post links at the moment...), which gives a "Sorry, this page isn't available" error from Facebook.

Could you please post a link to the correct Facebook page -- many thanks.

I just got a Hanna pH pen, calibrated it, watered my plants, and stuck it in the soil to take a reading. Which worked fine, but the soil (and especially bits of perlite) gets jammed up in opening that holds the electrode, and it was a real pain to clean. It's hard to imagine the pen can stand...

Well, I've been waiting for someone else to say it, and it seems nobody will, so I guess it's me. Before I do, I'll say it again -- I love this site. It's far and away the best of its kind, and what I say here is motivated only by wanting to see it keep on keeping on... And @sunni, please...

Thanks, @sunni, for your reply. I'm pretty new here; I wasn't aware that it was well known that there was only one admin -- I see your avatar says "administrator," and I've also seen members @Admin and @rollitup whose avatars say the same, so that looks like at least three. But maybe a member...

No disrespect, and I don't want to cause trouble, but it's disappointing to see @squarepush3r's post get no response. I have no more than a layman's understanding of DDOS, but it seems reasonable that once the attack is over, the site would be exactly as it was before. I understand the need...

Yeah, okay. I'll tell you what made me most nervous: In scouring the web trying to find out what was up with RIU, I found that there is a rollitup.org Facebook page. And there was no information there. You'd think if the site was down, there'd be a "Hang in there; we're on it" message on the...
