it might be my imagination but i see a lot of recommended nutrient formulas (like Lucas or Greengene) running the same ppms and ratios straight through weeks 1 until flush with minimal variation. on the other hand, liquid hydroponics companies seem to vary the feedings week by week increasing...

Do you think the problem was caused by too many photons or overheated leaf temperatures? In my severely limited experience I found using a laser thermometer to measure individual sections be a lot more reliable than going off of room temperature. Maybe there was a hot spot from lack of...

my girls are bashful... you know how teenagers can be Excellent idea. I know that nothing about indoor growing is natural but it makes sense to mimic nature where we can. Do you have any concerns about potentially reducing peak flowering time with the reduction in lighting? Beautifully made...

I've finally reached that point where my ladies look ready to flower. So far they've been vegging under 4 boards of Samsung lm561c LED's at 200 watts. The maximum wattage the lights can go up to is 480 watts, but that much will probably be overkill for my 11 square foot tent and un-supplemented...

i mixed my Peters 5 11 26 at 300 grams to 1500ml and though it didn't clump, there was some undissolved powder at the bottom of the jug. after adding 166ml to make it 0.18g per ml, i poured it into a bucket to stir more vigorously with a mixer which helped it dissolve a little better. probably a...

Wow that is genius. Could be a massive time saver. Im going to have to pick up some jugs to try this out. Will probably only use 2 litre jugs to keep the mix fresh. Do you have any concerns with this method? Such as the solubility of such a large amount of salts relative to the water or the...

I took a screenshot from Greengene's youtube video on Jacks 321. From there, I used Hydrobuddy with the elemental percentage of my versions of Calnit and MagSul and tweaked it to try and approach the numbers as close as I could while maintaining the ratios. With my nutrients, the straight up...

Thinking it over, next feed I was thinking of going about 3.2/2/1.2, which ends up with 104N-40P-182K-92Mg-124Ca-112S for a 660PPM total. The N is a bit low but having such high Ca is making me nervous. Then I will alternate with higher N vs lower Ca for a few days until I get some Magnesium...

I know it's too much but I have seen some other nutrient formulas that reach around that level so maybe it's okay for a few days until I get the Magnesium Nitrate. It's either the 11N/23Ca Calnit or more of the 5-11-26 feed. I have some kelp too which is about 1-0-0.2-2 but I don't think that...

Thanks for the helpful advice. Why I was using the 2:2:1 ratio is a comedy of errors. My Calnit isn't the recommended 15N/19Ca but rather 11/23, so I was more focused on getting the full dosage of Nitrogen while still keeping ppm's down more than anything. The other reason I came to this...

Groovy, much appreciated sir. I'll try to run the numbers on Potassium Nitrate but I think Mg/N might be cheaper round these here parts. Before I can get a hold of the MagNit, I'd like to boost my nitrogen using what is on hand... what would you say the upper limit of Calcium would be? To get...

what an outstanding trove of information. real nuggets of gold im4satori. thanks for asking great questions Skybound... for a master to appear there must be a student. i am not using Yara Calnit (15n/19ca) but rather a tetrahydrate form that comes out to about 11% nitrogen and 23% calcium. i'm...

I also thought it was strange that my PPMs were so out of wack. I'm guessing it's because my TDS meter costs less than a value meal at McDonald's. I may have read something somewhere that TDS meters don't measure the PPMs accurately since each salt affects the conductivity differently. It stands...

awesome! thanks, i'll save it to my grow documents. based on this, it looks like i can be more aggressive with the PPM of my week 6 veg feed. also, giving 950mg is 20% less than the recommended feed from both this chart and the Jacks 321 formula, so I'll definitely fix that for the next feed...

Thanks for the input Blitz, it's always great to have someone share the experience they've accumulated. Are you taking into account the addition of the Calcium Nitrate? The nutrient PPM of the feed is around 100-24-108-93-25 (N-P-K-Ca-Mg). I've been reading up on various nutrient regimens and...

here she is

Good day First time growing, it's been lots of fun though the amount of time in researching and taking care of them feels like a second job. It's quite the all consuming hobby. Anyways, my plant is growing nicely and getting quite large (about a foot tall, 2ft x 2ft) but there is quite a lot...

i noticed this too... obviously after the 3000k was in my posession. i kept staring at the charts trying to figure out how the marginal increase in red made 3000k a better choice for veg and flower as HLG recommends when the 4000k has such a huge boost in the blue range. in my uneducated...

I currently have 2x288 boards (max 480 watts) with 3000k lm561c diodes and have been vegging for about 3 weeks. I've placed it about 2 and a half feet above the plant and run it at 80 watts as anything more tends to get it droopy. My question is, would purchasing a 5000k board solely for...
