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.No, it's a poor choice for a number of reasons........loads of heavy metals and cheap ingredients , it's N-P-K is not geared towards marijuana in growth or bloom, it's not a "complete" fertilizer and numerous others issues- it's cheap for a reason, it's crap.

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?
A 1-1-1 NPK ratio is an all purpose plant food. What ratio/NPK value do you think is better suited for cannabis?20-20-20 is a poor choice of fertilizer for marijuana and any knowledgeable grower will attest to that.
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?Peter's growers report a build up of salts quickly, especially in flowering which screws with your pH eventually.
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'?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!
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=2540So is it yes or no.....? Kinda looking for a solid answer. If no can anyone point me in the right direction of plant food.
Think crushed egg shells would work for calcium j/w....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.
