Hey, not too worried about this, but I'm noticing the beginnings of a deficiency in one of my plants. Here is an image. From what I have read, this is most likely a Potassium deficiency, but might be an iron deficiency, although from what I understand, given that the plant is in veg, iron def...

And, in case the picture does not show the problem clearly: The new growth leaves are curling down. The old fan leaves, the big ones, some are beginning to curl and others are maintaining that good and healthy appearance.

I am using a two room setup. One room is in my basement indoors. I use it for vegetative growth and am growing under t5's. The temperature maintains somewhere between 70-80 at all times and the humidity is fine and I have had no trouble with any of my plants while they are indoors under the...

I wonder about that, and how to fix it, but then, I have a normal fan blowing at the opposite end of the room as the A/C. My in-line fan, however, is blowing from the same end as my A/C, which I guess I might have to switch, because that means that the bulk of the heat is getting pushed to the...

So I got my 24,000 Btu mini split up and running (finally), and it is working, but I am still getting a lot of temperature fluctuation in my room, by the reading on my thermometer. The A/C is set for 76 degrees, and the room feels cool, but the high-low reading is anywhere from 60 to 90. This...

Thanks for all the replies. Yeah, I was researching melting points and to melt plastic the heat has to be TREMENDOUS. Also note that the thermometer broke at a reading of 167, so how hot it actually got is really up in the air. I got lucky, though, not to have been killed (running CO2). So...

That's what I was thinking, too. The guy at the warehouse said it was the lights, though. As for electricity, I had a professional electrician do the work--we have safeties for the compressor outside, the panel breaker didn't blow. I can appreciate the luck, though. Definitely agreed that I...

No advice? Does anyone that uses a mini-split A/C have measurements of how far they keep theirs from the lights? Also, is it unwise to attach an in-line fan directly to a light hood?

Had a very rare thing happen... my A/C melted. I am running a mini-split system, 24,000 Btu for 4 x 1000 W bulbs (3 x HPS + 1 x MH). I just bought the unit. I installed it properly, vacuumed the lines. Left it overnight and went back to check the next day. The unit had malfunctioned and...

Wow, thanks for all the quick input. Okay, so I am running air-cooled hoods. And mine is also an inverter mini-split, so if I gather what you're saying, I should try raising the differential (right now I am set at 76) to allow for a little more fluctuation in temp? Also, it is reassuring to...

Hey, just revamped my grow room and have a question about A/C. I grow in WA state and am a legal medical marijuana patient (cancer survivor here, :-P:leaf:). I am currently running 4000 watts (3 1000 W HPS + 1 1000 W MH) in an airtight and insulated (R-19) room. The room dimensions are...

pH of water is between 6.5 and 7.0. As for ppm, I am not sure. They are in veg right now, under 24 hours of light. This is because I am growing in my garage (best I can do right now), and temperatures without the lights drop to forty or so. With the lights, the temperature stays at about 65...

I have four blue dream plants in Veg right now; transplanted them about a week ago into 3 gallon buckets and amended the soil with dolomite lime and a bit of worm castings. Now they are looking very unhealthy from how they were prior to transplant. Here are pictures. I don't know what is...

I have four Blue Dream plants in flower right now. One is approx. 30 days ahead of the other three. Each is nearly five feet in height. They are growing in soil and I am using Fox Farm nutrients and feeding them (with nutrients) every three days. That is, water with nutrients, then no water...

Hello all, I am a novice grower. I have eight clones of Blue Dream going right now. All of them have taken root and shown signs of new growth. I have them in small containers of organic potting soil under t5 fluorescent lights but on sunny days I move them outside. They have been in soil...
