Hi All, Curious to what color temperature COBs everyone is using for for flowering. I'm making a CXB3590 array and not sure which color to use. It seems like a good portion of people here use 3000k while others use 3500k (some even 4000k). Any suggestions for the optimal flowering color temp...

Hi All, I have a few plants in veg that are a couple weeks old, the older leaves on all of them have been developing brown spots(almost looks purple when it begins), and eventually starting to wilt away. Any ideas on what is causing it and how to fix it? +Soil - ProMix with mixed with perlite...

Hello, I have some new ladies that aren't looking too swell to say the least. I received some clones a few days ago, which were looking healthy when I got them. I gave them some nutes once (Low dose @ ~150ppm pH'd to 6.5 consisting of: FloraNova, Silica from Botanicare, two humic acid's [Sea...

I currently have 2x 1000w HPS lights in my flower room, and heat is becoming (well, has been) somewhat of an issue. Temps never go over 87 with lights on but that's still way too hot for my liking. I have a 400cfm fan making negative pressure in the room, and pushing that air through the 2...

Hi all! I have a few questions about my girls. Let me give you all a quick rundown of the afflicted plants. The big plants: - Medijuana strain - Just hit the 3 month veg time under 1k HPS, going to start flower soon once the new room is finished. - Nutes/water regimen: + Pro-Mix organic soil +...

Are these spots caused by thrips? Here's a few pictures of the afflicted leaves. If so, or if not, tips on combating whatever it is? Will imidacloprid work? I've heard spinosad works great but IMID is what I have on hand.

I saw this little bugger crawling on the top perlite layer of my new seedlings. Should I have concern that this is a spider mite or just a spider? On a side note: a few spiders always seemed to get into the cloning tray area and made a home out of the empty cells in there, this doesn't bother...

Man this blows! So I go to check the girls tonight and much to my surprise the center hanging support on my tent snapped and in result dropped my light hood and subsequently ripped my inline fan down and damaged a bunch of ducting as well. It completely fried my largest plant (Been vegging for a...

First grow. These babies have battled a lot during (initial bug problems, pH & over-nute issues, 95*F+ temps, rootbound, etc) their life since I received them as clones. All the problems have been corrected since the grow's started and I think I finally got everything under control. I know...

I'm going to be moving from my current residence within the next month (About 1-5 weeks depending on when everything with the new house is finalized) My plants have been vegging 24/0 for about a month now and have gotten quite big. If I switched to 12/12 now and moved the plants during then...

Hi all. I have a few "Medi-juana" strain plants, been in veg under a 1000w HPS 24/0 for about 2 or 3 weeks since I received as clones. They were definitely females when I received them, white pistils all over. I've got these lumps forming on all 3, are these calyxes forming or are they (gasp)...

Hi all. Here's what's happening thus far: I had a small bug problem (fungus gnats I believe, they came with these clones >:( [Can anyone verify that this is a gnat, picture below] ) and I tried a few remedies of which little helped. I read somewhere to let the plant dry out a bit more than usual...

Bad new bears! I know I did a big no-no and got some clones from someone. Turns out the clones had bugs in them, flying bugs. Couldn't get too close of a look to identify, I think it may have been thrips. I got some sns 203 from the local hydro store and soaked the leaves/soil with them...

Hi all! Here's a quick rundown of the setup: - 3 teens of the "Medi-Juana" strain - 4'x4' grow tent - 1000w HPS bulb - Pro-Mix organic soil - FloraNova Grow/Bloom nutes So I just got the teens tonight and I'm about to put them into bigger pots soon with pro-mix organic. I have distilled h2o...
