Is this a Mg def?

About 35 days from seed.

Nutes: GH flora micro and bloom 1:1 5-5-5 total at 5.8pH/350ppm (.7EC)
Conditions: 78F/70%RH
354w T5HO (4ft 6tube)

Everything was fine until I transferred from aerocloner to dwc bucket 9 days ago. They were getting 250ppm in the cloner and seemed fine, I put them in 550ppm nute solution when I transferred. They started to show this around day 5 from transfer, so its only been happening for the past 4 days.

On the fence if this is nutrient burn or Mg def? I've heard Mg can curl the leaf edges and yellow the edges on new growth..I lowered the solution strength yesterday and added a third of what I used for base nutes as calmag.

Hey yo . . . .

I do think Calcium and Magnesium are become deficient, you have PH in check . . . . . so, yes, if temps are in check, the ruffling of the leaves can indicate lack of clacium, ime, and the fan the leaves are just starting to loose their color between the veins, that's clear Mg deficiency on its way in . .. imho!

Try upping the solution to 575 to 600ppm. Do you have a hard or soft water version of GH Flora?

Soft version. My water has high alkalinity and i'd consider it soft water. Only 80ppm. The pH is 10.1 though. Im considering RO. I've read recently there is a lot of Na in our water, the report said 40ppm of it. A new report comes out in a few days, will check with it and get our water tested.

Na being a cation its going to compete for uptake with other cations likes Mg, K and Ca.

Never had these issues except for when I moved.

Uh huh . . . . so soft water for sure . . . . .

Well done for dialing the base nutrient down for some Cal/Mag, BUT, the soft water version of Flora, will handle that for you . . . .

What ratio are you using the three parts at please?

I'm a soil grower, but guys in our co-op do DWC . . . . plants that size are usually getting 0.9 to 1.1EC strain dependent!!

Forget calmag, I'd like to see the plants' reaction to 1.2EC solution ;)

i had it at 550ppm (1.1EC when I transferred them from aero to buckets) and started getting this issue and thought I may have bumped them up too much so lowered to .7EC

ratio is 1:1 micro to bloom. works out to a 5-5-5

Errrr yeah, but you're missing out on Magnesium by leaving out the Flora Grow dude, it's a three part designed to work together at different ratios throughout the grow.

The bloom is used in Veg to promote good roots, and the Grow is used in flower coz our plants need N still to make the foundations of buds and the Grow formula has a majority of the Mg in it, and a far bit of K too.

I'd be using 3:2:1 ration right now Grow:Micro:Bloom @ 1.0EC for now ;)

grow only has .5% Mg...bloom has 1.5% Mg

i was under the idea that grow is useless. in this trio

use 1:2 micro/bloom. and use RO for a week to try it out. try 5mL micro/10mLbloom per gallon. just a weak version of Lucas formula. i never had to add anything with Lucas as long as you use RO.

Nah man . . . . . read GH's schedules. . . . . . the three are designed to be used together.

It's been my choice for mineral fertilizer for 15 years buddy, I can tell you, they're a threesome!!


Yes the 1.5% in the Bloom PLUS the 0.5% in the Grow, gives you the perfect ratio of Mg with everything else . . . . .


The only time I cut out Grow is the last week or two of life, I move on to their Ripener then . . . .


Check it bro and get your plants dialed in ;)

Lucas formula been around way longer than 15years. 1:2 micro/bloom. no grow. must use RO water.

LMFAO . . . . it's day 35 man . . . . . GH invented Lucas Formula?? Was it not Lucas?

My Strawberry Cough wouldn't stand a chance with an old idea like that, many of the new monster strains won't, it's evolution, our plants are getting more demanding through genetic mixing etc.

I suggest we all need to start to re-think old ideas like "the lucas . . whatever" for some of these newer strains available today, a different breed of plant today than when old Lucas was "the thing"!!

Wakey wakey, get an up to date feeding schedule for these up to date hybrids!!! imho ;)

you don't find it weird that week 9 and 10 IS the lucas formula?

I see you don't understand anything about Lucas or how it was formulated. keep wasting your money on Grow.

NNNnnnnnnnope don't want to start understanding something so ancient. There is no wrong way, just different ways, I guess, I'l leave you and Lucarse alone ;)

These are new strains to be so I do need to dial em in.

Im not sure what ratios id mix all three at to get a 1-1-1 if thats even possible. TBH the grow seems shitty for a grow nutrient. Isn't it a 2-1-6?

If I mixed them at 3:1:2 (gro:micro:bloom)

I'd be at 11-13-27 no? I know MJ liks K, but god damn.

I'm new to this 1-1-1 and this is the only thing I found to gimme a 1-1-1 that I had on hand.

Your quest for a perfect 1:1:1 ratio will drive you mad . . . . .

NOT 3:1:2

3 GROW
2 MICRO
1 BLOOM for Veg

2 GROW
2 MICRO
2 BLOOM for transition

1 GROW
2 MICRO
3 BLOOM for Flower . . .


Or there abouts . . . . . fucking fantastic results dude!!!!

Yes low N and high K in the Grow but when ratioed correctly with the Micro and Bloom, that has 5% N, it's perfect stuff!!!

Im not trying to run lucas. I'm trying to run a 1-1-1. After trying Ionic(3-1-5) DG (3-1-2) and H16 (5-2-6) I want to give a 1-1-1 a try. I had some old GH nutes from when I first got into hydro and saw that the micro and bloom at a 1:1 works out to be a 1-1-1 so I tried it on these new seeds. Could that be the reason? Old nutes? They were purchased about 4 years ago.

So you think im underferting? I've heard I was overferting from a few people at ICmag and a couple users here.

Whats up with nutes and low P? That veg works out to 3-1-4(similar to Ionic grow which I got purple petioles, in fact all my grows I get purple petioles. Was hoping 1-1-1 would solve that.
