BMO fading late veg

I am a new user of BMO products. I have all 4 liquids and am growing out 20 plants in solo cups. 10 of the plants are in their 4th week of veg and am getting some hardcore fading. Non amended bio bizz light mix. I have had some trouble keeping them watered and some have developed necrotic spots because of it. Today I amended with some pure blend grow.

I have read that you should add the Foiler harmony in to get the npk right...

Just looking for some tips on how to properly use this product. In the process of reading the forum posts...

Bump...Anyone got any info?

I have used BMO and found it to be a bit light in the ass. You may want to supplement with another nutrient.

yeah i added 1/2 strength pure blend pro GRO....seems to be helping. I would like to get BMO to work for me though. Where they are in solo cups, the 1st set of leave (single) were starting to fade and i thought to myself that i would up the dose next feeding, the next day. When i went to feed em the fading had exploded and the 1st 3 leaf sets were have yellow... so i used the pure blend pro on em to make sure everything was alright. I have some more coming up right now and i think i'll try to get the BMO to work with them.
