I've never read a more misinformed post on this site, which says a lot considering the skill level of most of the growers here. Peter's makes some of the cleanest plant food available to us and I can back that statement up with reputable links. What I'd like you to do is back up your statement with reputable links.
In regards to it not being 'complete', we'll you're right but it contains more minerals than probably 9 out of 10 hydro store foods which are 'geared towards marijuana', right? So I guess MJ doesn't need all those essential elements, is that what you're saying?

I would like to know the same
20-20-20 is a poor choice of fertilizer for marijuana and any knowledgeable grower will attest to that. All elements are necessary for healthy growth, but some can be in the soil mix and not in the fertilizer. Use a "complete" hydroponic fertilizer for best results and that's not disputable. Peter's growers report a build up of salts quickly, especially in flowering which screws with your pH eventually. Flush often if you choose to you this stuff. And it's cheap for a reason- it's crap. Try to use a fertilizer that relies on organic ingredients, not the cheaper chemically produced salts like Peters. And that's a fact, Jack!

A 1-1-1 NPK ratio is an all purpose plant food. What ratio/NPK value do you think is better suited for cannabis?
Some formulas are saltier than others but I'd like to see a link to these 'reports'. Additionally, salt buildup is directly correlated to application rate so that has to make you wonder, how much were 'they' applying?
I promise you that your 'organic ingredients' are going to contain more heavy metals than mineral derived salts. Again, got a link confirming anything you've stated in regards to jacks being 'cheap' or containing 'loads of heavy metals'?

I do use walmart nutrients but this Peter or Jacks Classic is better than walmart....trust Homebrewer, he know what hes doing and im pretty sure that Homebrewer used this peter many years ago before the hydroponic fertlizers came out. And ask many veteran growers and some of them still use this JC products with excellent results.

If you're questioning the 'cleanliness' of jacks, here is the analysis of it: http://oda.state.or.us/dbs/heavy_metal/detail.lasso?-op=eq&product_id=2540
Look up other plant foods here to compare: http://oda.state.or.us/dbs/heavy_metal/search.lasso
Jacks is good stuff and they have a variety of products to suit your needs. Consider mixing in some dolomite lime to your dirt and feed your girls about 1 tsp of jacks every other watering or so. Maybe start smaller plants on 1/2 tsp/gallon doses. Jacks/Peters has been around for literally 65 years and you don't last 65 years in an industry if you're putting out a sh*tty product.

I've used jacks before and it works just fine as long as you dont use too much too often, which applies to virtually all brands of fertilizers. Trust homebrewer with what they say!

At that plant height, rain water with about 1/4 tsp/gallon of jacks and you should be good to go. Jacks doesn't contain calcium so you may think about going with half rain water and half tap water if you don't have any dolomite lime sitting around. If your tap water isn't too hard, consider 100% tap for that needed calcium.

I have been growing (again) for 3 years now. Have not tried peters, or dyna grow. I have studied quite aa bit of nutrient formulas and believe 1-1-1 is not optimal. 2-1-3 better meets mjs needs.
I switched to VEG + BLOOM from Hydroponic-Research.com about 4 weeks ago and am very impressed. I very much like that it's a powder developed specifically for mj, and a little goes a long way
