Can I shorten the dark time by a few hours without adverse effect ? Still weeks away from flowering...babies were sick, need to recoup leaves, still adjusting to new pots from being root bound etc.

Yes..mix any pre bagged soil with perlite, even if it has perlite in it.

Most cannabis grows best between 5.8 and 6.5 ( soil ) and even lower for hydro / DWC. 7 is too high and 5 is too low for any plant. They will grow at those extremes of PH but your wasting your time. These extremes cause nute lock out leading people to think it's low on nutes...so more...

Don't see any PM. See dis-coloration due to water spots / Neem treatment and nute problems. Dump the PH test strips ASAP...you can buy a simple test tube liquid PH kit for less then 10 bucks. PH test strips are crap..just exposing it to the air will change the color, not to mention touching...

Looking at the pics. Your plants were stressed to death. You can see the webs...gross! For every web you can see there are 10 you can't...at least until you break out the magnifier and start breaking open the buds. Not to mention residue bug spray, bug droppings, dead bugs, casings etc. I'd...

Uhh..thanks? But the problem is already solved...read my last post. They just needed to get used to the sudden tripling of lumens.

Moved the HPSs up another 6 inches. Woke up this morning....everything fine. Leaves arrow straight and aiming for the sky. Guess it was just too much light all at once. Problem solved.

Add more light...and not just Soft White CFLs ( Red Spectrum ) add some Full daylight CFLs. ( Even during flowering you still want to cover all the spectrums ) You can buy the socket and cord for about 6 bucks at Wally World. It's called a Bottle Lamp Kit ( for rewiring lamps ) plus 10 bucks a...

Re pot with good soil and perilite mixture ASAP...and try putting them under another light source. Even a couple CFLs will help. LEDs are cool and everything...but they still don't have enough blue / white light for vegging. I know it says it does..but it doesn't.

I use Smart Pots.( Love these things )...but I still use a 50 / 50 mix of soil and perilite. And the bottom 2 inches of the pot is nothing but perilite. Also keep the pots a few inches above the floor as this will help with drying. I have my plants on a metal grate about 3 inches above the...

Even a simple 10 dollar PH test kit can stop a lot of headaches. They are simple... fill small vial, add drops, check against chart. Also check PH going in and coming out ( Test run off water ) Also a PH soil tester is real cheap ( About 15 bucks ) You just stick it in the dirt. If you buy a...

Thanks..I'll take your advice about moving the lights even further up for now.

Ok... Nightime... 68 to 70 f / 60 to 65 RH Daytime...76 to 80 f / 40 to 50 RH ( 40 is lowest I've seen ) I have plenty of fans... 2 wall mounted oscillating fans that come on when the lights do....another oscillating fan runs all the time next to the humidifier ( I live in Colorado it's...

18 to 20 inches ( 3 x 150 watt HPS ) It's not heat...

I vegged my plants under 24+ k Lumen CFLs ( 9 x 2800 ) and now I'm starting to turn on the HPS a few hours a day to get them ready to make the transition to HPS ( Also keeping the CFLs going through flowering for spectrum reasons.) But within minutes of turning on the HPSs the leaves start to...

HPSs can veg a plant by itself. Done it before many times...it is a little slower ( growth rate ) during vegging but works out ok. If I had the money for a MH HID...I would get one in a heart beat as I know this is the preferred spectrum for vegging. That's why I'm using CFLs ( 6500 k bulbs )...

I normally veg and flower under CFLs and HPS. During veg I have the CFLs right on top of the plant and the HPSs ( 3 x 150s ) a foot or so above the CFLs. Works ok. Left for a couple of weeks and asked a fellow grower ( a friend who is now on my shit list ) to come by and water them. He's...

WTH ! Latest HT. Sept 2011 Page 59. I thought leaves were our friends ?! Now I've been hearing that during flowering to slowly remove fans leaves as these actually will slow the growth and potency of the flower. It's no wonder my SSH did so well, weight and size wise, because I was...

Some of the best weed I've smoked came from seeds I got in a " Schwag " bag. However it came from southern Mexico ( My friend who was down in Acapulco "Accidently " got some seeds caught in his hat band, he told me the weed was the familiar brick or pressed seedy Mexican crap....but the high...

My problem is I can't keep my water buckets at the right PH. This is just plain water...my nute mix keeps pretty close to what I want. I fill a couple of 5 gallon buckets once a week for plain watering and emergency flushes. I add the PH down...spend a couple of hours fussing with it and...
