Everything you mention seems to be good to go. Bare in mind, even though you might have the same genetics or strain, the phenotype might well be very different. I've had seeds from the same place but purchased a couple months later and the end result was different (foxtailing, appearance, etc.)...

I ran a single Spider Farmer SF-1000 (96 watts) in a 2x2x5 5 plants in 2 gallon pots last year to try it out and it worked great. Problem was tent height. Even though I flowered at 10" they ended up 8" from the LED after stretch which was too close and caused foxtailing. And that was after...

Yes, that would be fine. I use a 10x10 room and have a 4x4 area defined with the plants under the lights appropriately as your design shows. Not so sure I'd even worry about the reflector material. My room is painted white for the reflective capabilities and I have always had good yields. That...

Just to help any others curious, I found a PPFD map and it is good for 4x4 and would be overkill for 2x4. Excited to try it next grow though.

I just started veg with 3 plants in a 4x4 area in a 10x10 room. 2 plants have Spider Farmer SF-1000's in a 2x4 area over them and the other has a 315 CMH (3200K) over it. I had one extra plant I was going to toss but just won a Phantom Pheno 440 in a raffle so am thinking of removing the 315 CMH...

I just finished a grow in a 2x2x5 with the SF-1000 and it turned out well. There were 5 Blueberry strain in 2 gallon pots flowered at around 9-10" tall. They completely filled the tent. Ultimately I got 88 grams. Interesting, I did have to supercrop one of them since it was getting too high and...

I just accepted a position in Oregon subject to pre-employment drug testing and have a dilemma I'm hoping someone can help with. I am medical marijuana patient from Montana and in a coule of days I need to submit to the urinalysis. I don't use any other drugs and cannibis only at night to help...

After nearly 3 weeks I am seeing roots start on my Purple Monkey balls/Fire OG clones but am unsure when to transplant to soil. Right now there are a lot of what looks like spikes about 1/4 inch to 1/2 long running outward from the stem. At what point will I want to transplant? Thanks all...

Quick update on the issues I encountered. Last night I found my soil test kit and took samples from 2 plants, 3-4 inches down as well as a sample from the roots of a male I chopped down 4 weeks ago. The indications show a depleted/deficient P & K. N is spot on and PH is 6.7 in the soil. I am...

I am with you 100% on my application of amendments as well as my choice in nutes. I experimented with the same combo last grow on one plant and was very impressed by the initial growth but I now recall I had this same thing happen during flower and forgot to put the info in my journal. I used...

Chief, can you take a look at my new post. It has good pics and everything I have tried so far. Re-pot sounds scary due to their size which you'll see in the new post https://www.rollitup.org/t/cant-seem-to-figure-this-out.984339/

Organic buffer via the Dolomite Lime. I have a soil PH meter that shows 7.8 PH (I don't rely on these type meters), runoff shows 6.5 on my digital meter, the tap water is 7.0 I should add I have a 5th plant same age but was stunted early on in a 5 gallon smart pot under a 315 CMH that is not...

Took new pics with HPS off and updated the main main post.

Temps are 74-76 lights on, 72 off. PH is 6.5 in runoff.

Can't imagine def since there is bone meal in the soil and the bloom nutes has a 2 value. I've never used a P/K booster but certainly will if a P def is the consensus.

Thanks Chief. The gnats are gone and I watered with h2o2 for the larvae but it is just getting worse. I posted a new thread since I am thinking P toxicity or maybe root bound now after more diagnosis. Also put potatoe slices in the soil and see nothing on them after 4 days. Never heard of the...

You bet. Lights go out in 20 minutes then I'll head in and take pics with incandescent

I have 4 plants in their 5th week of flower and can’t figure out why the leaves are yellowing in the middle of the plant, turning brown and dying. This just started occurring 1.5 weeks ago. I water every 2 days with nutes added once a week. PH runoff is 6.5, ppm 850, using 1000 W HPS 12/12...

That is awesome. Based on this I am suspecting a P toxicity. I am going to post a new thread with all my attempts and seek advice there.

Thanks. I have considered for years trying hydro but got very good at soil. I just moved and this is the first grow in this new room. My next grow I will be doing a couple DWC to learn more in hydro.
