Hey all! --

First, thanx for com'n to look into my plea for help!!

History: These are my Superfruit x Blueberries, as featured in the thread in my sig. They are on day 24 of veg, in 5 Gallon Bucket DWC. On the 20th {last Saturday}, I moved 'em from under 4' Shoplight Fluoros to an air-cooled 400 watt HPS. At the same time, I raised their nutes {1 Part GH-Micro::2 Part GH-Bloom} to ~550ppm@.5. For the first 24 hours I kept the light raised over 2'. I have gradually lowered it to within 12". Temp at the plants is comfortable to the hand, and damn bright!

Are they gett'n Nute Burned? I would not have thought 550ppm {tonight, closer to 450ppm} would be too high... Especially with the size of the #7 plant!

Or is there another problem here?

Any and all input is appreciated!!!


Here're the pics from just a li'l bit ago:


Thanx again for any help you can provide!!!

Look's more like mag def. imho .

[BuzzBob]

Thanx Teresa!!

I was think'n that too, but if that's the case, this cross is a serious Mg Pig!! I am already doubling up the GH-Bloom, with all of its mag...

I am really inexperienced at these things, though... That's why I posted!

Hmmmm... I wonder if it could be a lockout due to pH... I am currently using drops for testing, as my meter fritzed out on me about a week ago. I believe my pH to be right around 5.8... Perhaps I should try and raise it up some, and toss in a dose of Epsom Salts, eh?


Nice to meet you, btw! Thanx for coming in to my call!!!

Buzz, there aint no way you can burn them at 500ppm. I agree with T girl, mag def. Looks like the same thing I just went thru. Keep the ph up around 5.8-6.0 and give epsons, it cured most of mine but i'm finding I just cant seem to give enougn epson to satisfy them. Someone mentioned cal-mag or mag pro somthing like that works a whole lot better.
I dont know why GH dont add more mag, after all this time, you would think they would see the problems were having.

Hey 70s! --

Thanx for the added opinion! Mucho appreciated!!!

That's enough of a consensus for me! So that's what Ima gonna do! Push up the water/nutes to the main res, mix in like 1 tsp per gallon pre-disolved Epsom Salts, and get the pH into a comfy 5.9-6.0 range.

Yeah, I keep reading about mag def problems... My AKs that I just harvested did fine with just what GH-Bloom was giving under the Lucas Formula, but its look'n like that ain't enough for the SFxBBs!!! I may have to look into CalMag, or something...


Thanx again for the help!!!

Hey there Buzz

Yea definately not nute burn...you could tell nute burn by the very tips of the leaves...it starts off wit a dry tip which indicates too much nutes...but in your case, looks like it isn't gettin somethin she needs...can I ask you a couple of questions?? I assume your 1 tsp of micro and 2 tsp bloom are per gal?? How come your making a flowering mix while your in veg?? Also, how come you left out the #2 part (gh grow)?? Your mix should be 1-1 1/2 tsp micro-2 tsp grow-1 tsp bloom...and when you wanna go agressive it should go 2 tsp micro-3 tsp grow-1 tsp bloom...this is how I run my 3 part gh program...and you shouldn't worry about your ph @ 5.8...your good there!!

Hey SQ!!! Always a pleasure to see you drop in! And even more of a pleasure to gain your insights!!

Am I wrong?? After I looked, and looked, and looked at the Lucas Formula, it basically sticks pretty much to a 2 to 1 ratio of Bloom to Micro, regardless of Veg or Flower. In the original Lucas Formula, it provides a recommended number of milileters of nutes per gallon for seedling, veg, and flower. Instead of doing that, I monitor ppm/EC, and just raise it gradually, using the same ratio...

Did that makes sense? Am I off base with that??


[edit] Oh!!! I see now that I did not originally make reference to the Lucas Formula... Maybe that is what threw you off, SQ; Sorry! Yeah... With Lucas', you do not use the Grow at all! [/edit]

[So Quick]

Too be honest Buzz...I've come across lucas's thread, but I've never really finished it, so I can't really comment on his belief's...I see alot of people mention his technique, so it has to be a successful blue print!! I've never had any problems wit my experience using the 3 part gh, so I never had a need to seek any answers...and also my imput isn't in any shape or form to challenge the Lucas Formula, but strictly my own advice on what I do to get my results...just had to throw that out there, cuz some folks can really twist things up

But anyways, I always use the grow in veg...however I could see scratchin it after the first 2-3 weeks of flowering, which is right around the end of the stretch

Well, I am really sooo new I do not *know* from much experience...

On my first grow {some bagseeds}, I was using all 3 parts, and had a Mag Def. I augmented with Epsom Salts then to correct it... Unfortunately, that whole grow went down as all male... :( But they were damn healthy when I chopp'd 'em!!!

My second grow {first to harvest, just last week}, I switched over to the Lucas Formula Managed by PPM {as I have called it}, and did not experience any Mag problems at all...

But it does appear that this strain/cross may be desiring a li'l something more than the bagseeds and AKs did...

I used the 3 part one and had no problems at all.
I used this chart i found on the net.



Also,iam curious if a person could get magnesium from a pet store.People that run salt water reef aquariums,add magnesium frequently to supplement their corals.Would this same magnesium be ok to use in hydro?I would think there is some one here smart enough to figure out the right ratio of dilution for hydro. Just a thought.
