Thanks Renfro! I know you do, your grows are what inspired me to check it out, if you don't mind me asking, what is your mix per gallon?
Give this a go, it works for a whole cycle. If you wanna pk boost it you can drop the epsom for weeks 3 and 4 and add like 0.66 to 1.0 grams per gallon of MKP. Call it Renfro's magic formula lol.

Per Gallon of RO H2O
Armor Si = 2 mL
Calimagic = 5 mL
Epsom Salt = 1 gram
GH Micro = 6.67
GH Grow = 6.67
GH Bloom = 8.33

Shouldn't end up more than 2.4 EC, more like 2.2 - 2.3 for me with 2 ppm H2O. If it's too strong for your liking you can cut the mix with some water but thats how I use it.

If in soil I have found you don't really need the epsom but in coco or hydro you do. Soil doesn't seem to mind it either way.

This chart is the feed w/o PK boost:

This chart is the feed sans epsom salt and with 0.67 grams per gallon of MKP.

I dunno what medium you are in but in soil I ran the pH at 6.5 and in pure hydro 5.8. Coc believe it or not I found I had to run up at 6.3 - 6.6, mostly at 6.4 - 6.5. IKR? Thats with Mills DNA coco cork. I tried 5.9 - 6.1 and they were pissed. I recognized the symptoms from when I was running my soil too low and I raised the pH, bam happy plants. So you may have to figure out what pH works for you if using coco.

Thanks Brother, I will probably run soil. Thank you again so helpful! If I can ask a favor? Give Lil Renfro and Clem a belly rub for me!

I love my GH.
Yep, im all about the GH too.

Amor si
calimagic
micro
bloom
Dry koolbloom

i dont even use the grow when running H3ad formula. it seems to work, this is my 3rd crop using this mix, i also still do as you do and taper N and raise pk a little the closer they get to harvest.

Everything is looking good Flatrate, nice job bud, best of luck the rest of the way.

One thing I really love about the GH Three part is the flexibility. You can adjust it really easily if your plants ask for something. For a DIY PK booster with a nice 1:2 ratio of P:K you can use 1 gram of Monopotassium phosphate to 0.333 grams of Potassium Sulfate. That provides elemental P:K PPM of 60:114 if used on 1 gallon of water.

Thinking about the things discussed I am really liking the GH idea. Not only it is a proven product, I can get it locally. With NFTG I have to order it from Oregon and spend $150 a pop to justify the shipping deal, or drive 120 miles round trip. I have done the trip for the #4 soil, I still might use the soil its a really nice blend and no need to add more perlite as it already has a ton.

Then again I may try my hand at coco coir, the thing that makes me nervous about that is the need to water more often. I still have all the parts that @diggs99 told me to get to set up a automated watering system so maybe it will soon be time to get that going.

@Renfro Thanks again for providing the info on RMF (Renfro's Magic Formula) and that you start with RO water, I don't have a RO system. I will be using tap. My tap is PH 7.9 PPM 230 on a 700 scale, will this work?

While I got you guys here let me ask a question or two. I didn't want to hijack someones thread with my own questions. LED and temp. I seen you both respond to a thread about the subject. Lately my temps have been 82F or so with a leaf temp of 78-79F. You guys say mid 80's is the best, are you talking air or leaf or both? I still got some room on my light to turn it up more, and this is with out any aid from AC.

Also at times when I tried leaning on the light the plants didn't respond well. I guess I am a bit worried about running the electric bill up, what do you guys think, should I just be a man and crank the light up and turn on the AC? I am going to experiment with some things today and see how it works out.

Thanks guys!

Thanks Ren! Oddly enough at 7am when the light came on I went in there and set the light on kill, all its got. I've checked it once an hour since. Just checked it again tent is 82 with a leaf temp of 76-78. Made me look like a liar, LOL.

Ok boys, lets keep this secret between us... Looks like I will be checking out Mega Crop. Just popped on to our Amazon account which my girlfriend and I share. I placed it on my Xmas list before we had this talk, and I forgot about it. I noticed she ordered it for me. I am not going to say anything and since I will be getting it will check it out. But will sneak GH into the mix. She'll never know a thing!

Just a verbal update, pictures will come soon in a couple days. Plants are doing great! I started expanding my little grow operation with the addition of a 4 X 2 tent for veg. I got it in place. After throwing around a few ideas about a light fixture for it I was going back and forth on some options, plus my lovely girlfriend offered to get me what I wanted for Christmas.

I was seriously thinking about HLG QB's, but in the end I pulled the trigger on another Timber! Had another good but brief conversation with Dan, I could tell he was busy. Told him I was after a 3 VL, and had Ms. Flatrate call him up right after to seal the deal. Hopefully I will have it hanging by next week.

@RainDan. Once again thank you for top notch customer service and providing me with top notch fixtures, happy holidays to you my friend!

And again I am fucking stoked!
