Athena Pro way more diluted than they advertise?

From 2 LB bags of bloom being solid as a rock to ml/gal rates being totally inaccurate by up to 1.0 EC (500 PPM) this line really disappointed me.

I have used Jack's and MaxiBloom with no problems, quite accurate measuring & mixing results. Athena is worlds off and for a 2 part it makes it so you have to do a 40/60 ratio by solution EC not by grams or ml/gal of concentrate.

I was using MaxiBloom for the last few months now and have only had issues with pH crash in coco mid/late bloom but I also use RO water which is known to cause this issue due to lack of buffers.

Is anyone else having issues with their ml/gal recommendations? I carefully mixed 2 lbs to a gallon (4 lbs total for 2 gallons of solution @ 2lb/gal), made sure to add 1.5 gallons, mix then fill the rest the way to 2 gallon marker on measure master bucket with RO. Shot for the 3.0 Target EC using their measurements and the EC was 1.0 short after mixing.

This means forget any price per/gallon math they advertise. You are getting way less for your money than you think.

THOUGHTS? Also, why is it possible to feed 3.0 EC start to finish? I haven't used any other fertilizer that wouldn't roast plants doing that.

I just recently did it this way, but and my EC did seem lower than expected as well, but I was adding to an already diluted res so I wasn't sure. I will say, it took forever for the bloom to dissolve fully.

About to mix by batch tanks later this week. I'll be using tap water, read that you need Athena Balance if using RO.

I'm using soil so I might set my EC around 2.0

You don't.

Balance is Potassium Silicate which is used as pH UP in RO water.

I don't like the idea that I can't even calculate the actual cost per gallon due to their own measurements being way off. I found other links supporting this information. I'm the last person to be shiested and with how much of their products they give away to people for free it speaks volumes.



idk something about having to use pitchers of solution to reach my EC goal makes me think the value isn't there at all like people claim.

How's the plants looking?

I haven't had a chance to use it, once it mixed all fucky I switched back to MaxiBloom. I'll just start amending my coco with lime to stop pH crash later in flower or irrigate in more frequent intervals.

Feeding at 2.0 EC, halfway through flower.
