No - I say don't worry cuz it's your tester that is off. Your soil is probably right at 6.5 right now, and will stay there unless you do something really whacky to it. Basically any name-brand commercial potting soil comes out of the bag at 6.5. About 99% of the plants in the world thrive at...

Uhhmm... so they say. Anyone who makes those claims to me has to show side-by-side scientific proof first. A lot of nute producers make these claims, but independent controlled trials of their products show no benefits. NPK and the 13 essential micronutrients (Ca, Mg, Mn, Fe, Zn and the like)...

Hmmm.. wasn't me that made the "underdeveloped root" comment; have to think about that one. What are they showing? Spots, curls, burnt tips? Pop up a pic if you can.

Aha... yes, those probes are bunkum. The drops are much better; pH paper is easier to use and just as good. Cheap pH meters (like the $50=75 variety) have a lot of problems; I wouldn't waste the money. For soil, drops or paper have all the accuracy you need. Soils buffer pH very well, esp when...

Yes, blown up as in curled leaves covered with dead brown spots, followed by leaf drop and buds that never mature (cuz they need the energy produced by the leaves to do that). I know a lot of nute producers say that -- start using flower nutes right at 12/12. I can't say why .... I've seen a...

What was "over 9"? The soil? Your water? Nute solution? If you're in soil, you meant water or nutes, and your plants look healthy, I would just stick with what you're doing now -- potting soils have an abundance of acid buffers in them. It would take a buttload of pH 9 water to raise a soil...

I would stick to grow nutes until your stretch levels off. For the first 4 weeks or so of flower, your plants will be adding way way more leaf and stem than flower. That means high N demand, and grow nutes. High P and K right at / after 12/12 = blown up plants.

Feeding high-P food right after the switch to 12/12, when they still needed a lot of N -- burned the shit out of em. They were fantastic plants for 5 weeks up to then; blew up a perfect 1st grow.

Yup.. that's right. It is a little bit of an odd formation, but MJ has a lot of variability.

I find it tricky to get my 400 just right over a set of seedlings; 1000 might be trickier yet. I'm going to a T5 bank for seedlings next year.

Harvest in stages - the plant doesn't mature everywhere at once. If the tops mature first, harvest them only then lower your light to the rest of the plant. You won't believe how much that low fluff will tighten up.

Wow.... very nice:clap: Here's mine -- bubblelicious at 59 days 12/12; and two superskunks at 52 days of 12/12 from seed.

I wouldn't worry about that distance factor too much, other than to keep your light at say, 8-16" over the tops. For wattage per square foot, I would just go with the general grow area recommendations based on the 50W per sq ft ideal -- 4x2 for 400W; 3x3 for 600W, etc. My grow area is...

Seeing any sex on those Satori's yet, weedy? Should be by now... Are you scoping for pre-flowers? BTW, weedy is not a guy, y'all...:-P

Have you checked under the leaves for mites or insects? That looks more like bug damage than anything.

Nope.. all the same problem, expressed slightly differently or at different stages of progression. Too much P and K at a growth phase where N is in the greatest demand. One thing for certain-sure - it isn't moisture stress one way or another. That curl in the top leaves is classic phosphorous...

Good question; I've never run anything 12/12 from seed. I only did it here cuz I was gonna get some superskunk out of this grow come hell or high water. I just have the one light and room, so I had to plug em in in the middle. They're at 52 days, with say, another 5-6 weeks to go? So, about...

It is interesting to take some little smokes along the way. I sampled some early sativa bud last year around 5 weeks -- the buzz was like some kind of cheap amphetamine or something. Very jittery, racy and not all that pleasant. But strong, though.... freaky. That definitely convinced me to keep...

Helluva setup you have there; I'll check out your pics later. Interested to see how your Bub's look compared to mine. I was on PANGcake's Bub's grow - he had classic indica phenos that really don't look like mine, even tho we had the same bean source (Nirvana). Same branch-breaking bud weight...

Holy crap, so you have 800W of HID in a 3x3x5 area? Wow.. Sounds like you've got the temp / vent control to handle it, obviously. How'd the sweet tooth pan out for you? Any pic's of the bubblelicious buds? Curious to see how they compare to mine. Bubblelicious is supposedly 75% indica, but I...
