He hasn't fertilized yet because he's afraid of causing more problems. So you think they need more P and K? That's a bit of a tricky combination for me because I don't have potassium hydroxide. I suppose I'll just tell him to buy seaweed extract and maybe add a dash of copper phosphate because...

Yeah, he had pretty bad magnesium deficiency on his last run. I grow soilless, and he had to supplement just about the same amount of magnesium as I did for the same strain.

I calculated the dose for him. I measured the pH of his tap water with different concentrations of ascorbic acid and extrapolated a graph. I then used that graph to estimate how much would be needed to get a pH of 6.2. Although, his pH was 6.7 when I measured today, so I suppose his water has...

No, he hasn't. He doesn't like to foliar feed.

A friend of mine is growing eight plants indoors. I believe they are about five weeks old. They're in makeshift one-gallon pots (will transplant to makeshift five-gallon fabric pots in a couple days). He waters them every other day at the moment. Tap water pH'd to 6.7 with ascorbic acid (about...

My friend asked me for help diagnosing problems with his plants. He has nitrogen toxicity and magnesium deficiency for sure, but I don't know why a couple of his plants have twisted and wilting new growth. I believe it's phosphorus toxicity, but I want to ask you guys to be sure. Strain...

I got another idea. Put the lights in a semicircle against the circular wall. I haven't done much thought about it; I'm just throwing the idea out there.

Not if there's a concentration of light in the center or on the outside ring. With only one rotating mass, one side of the plants will always be facing the center, and the other side will always be facing the outside. They would lean in the direction that has stronger light. Same would happen if...

If you line up the lights @ 7.8", 15.6", 31.3", and 39.1", then this is what it would look like: I adjusted the brightness so that there's no "clipping" so you can actually see areas that are brighter than the center points of the lights. The numbers I chose were if you were to divide the...

Here, I put this together just now. I set up the centers of the lights at the radius that you suggested. The circles emit a white gradient over a black background using the inverse square law. Overlapping white stacks as it would with real light. It looks like you hit the nail right on the head...

48 hours just to wilt? That's extremely reassuring! What's the height of your flood table and the volume per plant of your reservoir? I was pretty set on doing DWC, but you guys are strongly swinging me towards ebb and flow. I still want to go with the 3 different strains, even though it'll be...

My neighborhood loses power for usually about an hour a few times during the summer due to aggressive thunderstorms. If it happens while I'm away or during the night, how much would it hurt? Losing power for several hours is rare, but I'm still worried about losing months of progress in case...

I had never thought of adjusting the nutes so the most sensitive plants were happy and then hand watering the hungrier girls. Thank you very much for that idea; that's certainly something that will greatly impact my decision when the time comes. Also, how long do you reckon I'd have (until...

I built a 4'x3'x3' flowering box that was initially intended for a soil SOG with 6" square pots. However, after realizing that differing strains and even different plants of the same strain consume water at different rates, I want to switch over to hydro after the first couple of harvests. My...
