New Grower 8th autoflower about to pop/past stunting issues

[Icenitribe]

Hey, it's been awhile AFN
so I'm about to start my 8th auto and of that 7 previous plants all but 3 became stunted.my best one was in a hempy pot with verm&perllite so I'm hopping to improve upon that one. Except I'll be using MAPITO instead. My main question is should I start it in the mapito by inserting the seed in a piece of the polyurethane foam or start it in a jiffy plug and transplant? Also I have GH rapid start,what is a safe starting ppm or should I start in ph'd water only and add food later?
I thank you for your replies and advice.

I've never seen anyone use Mapito before so had to go look it up. http://www.alchimiaweb.com/blogen/grow-marijuana-plants-mapito/. From what I see it looks like you can go straight into it, no need for the Jiffy pots. Since it contains rock wool it has to properly conditioned first. It contains no nutrients so I would suggest giving them a mild solution right from the start. About 1/8 of the recommended amount should be sufficient. I would shoot for about 200 - 250 ppm at the most.

Mutant tripod and high aeration ph

Hey muddy, sorry not to update this a little more soon! What can I say,I did put the seed in the MAPITO after it sprouted. First off if anyone plans on ordering a free sample of this it probably rules with photo plants but it takes a long time before it starts to ph balance(lost a week of growth because it was at like 9 ph!) I soaked it in 5.5 ph water for 30 mins then drained(like the directions say and all rock wool) but I think that with the super airy foam holds lots of oxygen in it which contributes to the ph going up to around 6.3(could be worse)but I've noticed it's become more ph stable every time I water (I ph offset and aim at 5.8)so when I recyle it I'll have less work(adding acid droplets and flooding daily)..I'd like to know how rare trinode cannabis is(if it was photo if cut it till moonlight)I've had a plant top its self before but this is my first fully vertical trinode! Plus all 5 seeds germed and are fems from this batch from Herbies so happy times with Tri-node...I'll update this mutant too(it's only under 250 watts led)so if tripod turns to Tri-nodeisaurus Rex

so here is an interesting update.. My last auto nyc is a tripod!!

Day 40 update

So this girl is about half way through and looks to be another dwarf,could the reason I keep getting stunted autos be genetic? Last 5 seeds I've popped have all been from pyramid seeds(discounted from Herbies)and I use GH flora series nutes. I Had some ph issues with the new MAPITO but it has since stabilized. I need someone to recomend an auto strain that isn't prone to dwarfism so if it gets all stunted I know for sure it's something I'm doing wrong. So here she is-
