Here’s the problem - only 0.1% Mg in Micro and none in the other two.

What a crap diluted product line! You’re paying for artwork.

More reason for them to convince people they need to spend more money on their products.

Would you recommend I start adding cal/mag - Epsom to the feeds from now on. If so how much would you recommend I add to advanced nutrients snake oil.

It's not soil I'm growing in its coco/perlite.
I don't know if the coco hold onto chemicals in the way soil does but I know coco/perlite is inert so doesn't have chemicals naturally in it like soil and as far as I'm aware coco can't dry out in the same way like soil.

It's don't just runs thru.. never could do that growing. I tried few times. To much work changing out water all the time. Went college on stuff like that but I didn't listen one bit.

Since 1ml/gal of Micro only provides 0.26ppm of Mg, I would start with 0.75g/gal of Epsom. That gives you an additional ~19ppm of Mg, which is about what you want for the age of this plant. Your max dose during late veg and flower would be 2 to 2.5g/gal.
 
Well I use this line of Nutrients and has been great! I use half the recommended doses and always use cal mag with every feeding. I first add cal-mag, mix, then wait at least 20 minutes before adoing nutrients. I also do in same order as earlier mentioned first the Micro,mix, then Grow, mix, followed by the Bloom, mix. Never any issues including ph levels, ph perfect is beautiful . Here’s my last grow using them Quebec Blue.

Thank you for this.
Exactly the kind of answer I've been looking for. One more thing if your able to ?
Could you convert the amount of Epsom needed to litres, im in the UK so I mix by litre and its imperial gallons as apposed to metric.

Thanks again, your help has been a god send.

I appreciate your reply.
I've used it in the past with zero issues but never from the very start, last time I used it the plants were going into flower, this is the first time using it from seed. The cal/mag is most likely where I've went wrong but AN neglect to mention the use of calmag alongside their pH perfect. I was following their budlabs app, if only it mentioned that cal/mag is actually needed it would have possibly saved a newbie like myself half the battle with the problem in the first place. Other nutrient brands I've used recommend the use of calmag alongside their nutrients feed charts so why not AN. According to them all that's needed was micro, grow, bloom, b52 and Voodoo juice then in flower micro, grow, bloom, b52, big bud, overdrive.
 
I’m just starting a new grow, currently on day 4 since breaking soil (pro mix bx) and the advanced nutrients recommends 1ml per litre. I use a 4L bottle of distilled water and do half the recommended .5ml per litre. So for entire 4L bottle I first added a .5ml of Cal-Mag, wait 20 minutes, then add 2ml’s of each micro/grow/bloom instead of what would be the recommended 4ml’s of each. I simply follow this throughout grow, worked for me.

Thank you for the reply.

I'll try this on the next grow, only difference is I use coco not soil. I did start off with 0.5ml of the micro, grow, bloom but the plants were showing deficiencies really early on so upped the amount. Again maybe if I had used calmag from the very start and continued with it the plants might have been much healthier. Both bill and Felipe mentioned with coco that calmag is needed but I just didnt know exactly how much was needed throughout and never added it the last two feedings. Partly myself to blame I suppose.

Yeah, coco is different, I hear ya. I just play with it and let the plants tell me what’s going on, adjust accordingly. Over all I’ve really enjoyed the PH Perfect Advanced Nutrients and how simple it’s allowed it to be. Cheers.

There are approximately 3.78L/US gallon.

@FelipeBlu

Just noticed what you've previously said and not sure if its a typo or not but you mention 1ml/gal of micro.

Is that 1ml of micro to every gallon of water
Or
1ml in every gallon of micro contains 0.26ppm of Mg.

Thanks

The recommended dose is 1ml/litre for clones and seedlings.
My plants are at 4ml/litre of micro and same with the grow and bloom.

That surely changes the amount of Epsom needed ?
Click to expand...
4ml/L of Micro provides about 4ppm of Mg (4ml/L x 3.78L/gal x 0.26ppm/ml). The dose of Epsom that I recommended will provide about 24ppm Mg to the ~96ppm Ca provided by the Micro at that 4ml/L dose. This is almost a 4Ca:1Mg ratio, which is a bit high. An acceptable ratio is about 2:1

There’s a reason that I recommended Epsom instead of CalMag. The Ca:Mg ratio in this product line is way off (2.4% Ca to 0.1% Mg is 24:1!)

If you add CalMag instead of Epsom, you will be driving that ratio even higher - to the detriment of your plants. If anything, due to the 96ppm of Ca provided by the Micro, you would want to double the Epsom dose I recommended to 1.5g/gal (~0.4g/L) to try to keep the Ca:Mg ratio closer to 2:1

Is this clear?

As much as I would like to say it makes sense as someone relatively new to growing it doesn't. Its all just numbers, ratios, calculations and ppm's of something I still have a long way to learn that im seeing. Keep in mind I'm not a seasoned grower.
Dumbed right down, how much of each micro, grow, bloom, Epsom is recommended per litre of water.

I've been going by the recommended dose on the label of a bottle which would be 4ml of each since the plants are more or less in week 4 that would be the recommended dose. Again according to AN the ratio's for each bottle need to be the same otherwise the pH perfect apparently doesn't work.

Again I'm lost, this shit is just starting to confuse me even more.

No problem. You aren’t really expected to understand all this - I do get carried away.
I just got back from sailing, so give me a little bit to do some math.
 
Okay, here goes..

2ml/L of each M, B, G (which is appropriate for the age of your plant) provides:

100ppm N (OK)
23ppm P (OK)
132ppm K (OK)
48ppm Ca (a bit low - I like about half of K, so at least 66 ppm would be better)
2ppm Mg (ridiculously low - I like about half of Ca, so at least 33 ppm would be better)

0.25g/L of Epsom provides 26ppm Mg, so that would bring Mg up to 28ppm (a little low still)

To address the low Ca and Mg, you could now add 0.5ml/L of CaliMagic (1%N, 5%Ca, 1.5%Mg), which provides 25ppm Ca, and 7.5ppm Mg. This would bring the Ca up to 73ppm and Mg up to 35.5 ppm, with only a 5ppm increase in N.

It’s accepted practice to mix in the CalMag first - before Micro - as if the Ca and Mg were already in your water.

Which reminds me - this assumes that you are using RO water. If not, do you have a water quality report? You might have sufficient Ca and Mg in your water already.

Ok so 2ml/L - m,g,b
0.25g/L epsom
0.5ml/L calmag

Its plain tap water i use. I gave a water qaulity report last time, in your own words it lists almost everything except Ca and Mg.
If it helps the water is soft water, pH normally tests around 7.0 - 7.1 before mixing with nutrients
