new growth yellow tips

Nutrient burn. You overfed.
Where did you get the idea to add vermiculite to Pro-Mix? Usually you don't want to retain water with cannabis, unless perhaps growing under HID?
Where did you get the idea to use soilless (an organically inactive medium) with Fox Farms nutrients (for organically active medium)? That may cause you a problem. I would use a synthetic fertilizer with Pro-Mix. (Or, add some soil to Pro-Mix HP, the way I do, and then treat it as soil.).

Possibly too much magnesium since it is on the newest growth. But hard to grasp that with what you have posted. A foliar feeding of something with manganese in it would halt the yellowing if it is. Are you not using micros with your feeds?

It's the same exact mix a greenhouse legitimately up the road use for all there plants, weather your opinion or "knowledge" say it should or not it does it actually works just fine. I usually compost and ammend soil using teas and organic nutrients but I'm in a new location all new equipment like no fucking budget so I went with it and like I stated above up until now its been working juuust fine.
No as stated above kind of a wing it grow while I get all my compost and new equipment rounded up.

Hey man I'm not being an asshole especially not to you if anything the comment above seemed kind of rude I respect you greatly hot rod love your work, I apologize if you seemed to think I was coming off as an asshole i evaluate everyone's opinions before i disregard them. Sorry I reread that reply and I get where you'd think I was being an asshole sorry my punctuation is terrible I meant like as stated above in my previous reply not my first one just didn't want to retype the Info I had posted on that same comment man.
No, he's right. After I posted I thought I could have worded my question better. I thought he was a new grower and wondered if he had randomly picked an organically inactive medium (and organically active fertilizer). Or, if he had seen someone do it successfully. (I wouldn't think it optimal.). I could have worded my question that way instead of "where did you get the idea." That sounds antagonizing.

Ya I know and I wouldn't of believed it myself if I hadn't seen, been apart of it and watch the veggies and flowers they put out, and it hasn't been entirely optimum for cannabis, but its done the job.
I could see that. Are you thinking your pH is too high?
This makes me think about my concerns using organically active nutes in an inorganiclly active medium. For example, which ph-uptake chart applies? I don't know if this is a concern or not. I add 20% soil to my Pro-Mix HP and treat it as soil (growing with a lot of organic nutrients.). I don't think that 20% soil would make that much difference.
A chart I have says calcium suppresses boron. If you use tap water, what do you know about it? (The ppms?, what they're composed of?).

Fox farm liquid nutes aren't exactly organic.

Honestly I'm not sure ph and ppm meter broke probably 5 weeks ago along with my 1000w hps during moving to a new location I threw these in as a quick and easy untill tax returns guess ill just go get one. It honestly might be because I was using distilled and started seeing micro deficiencies switched to spring about 4 feedings ago but have been really really light on ferts so it could be ph to high and leaching of micros from distilled in medium not entirely sure, I figured ff was pretty acidicand would drop the ph of the tap down to a doable 6.6-6.8 at the highest but I might be wrong I haven't tested I know out of the two plants doing it I gave it a little bit of fert instead of water but very little and there seems to be slight improvement. Can't wait for Feb to be back to compost no till. I knew if I tried simple it would end up being more difficult.
You haven't fed much? That could be the problem. Pro-Mix HP has almost zero nutrients in it. It's good for about the first seedling week. I would feed one plant about 400ppm and see what happens.
I hate to see you have to buy a pH meter. I don't think pH of the nutrient mix matters in soil. I don't pH. You talked about using a good soil next time. It seems like a waste to buy a meter. But, it may be necessary using a soilless medium.

Some people suggest there is no need to ph nutrients in pro-mix because it stabilizes ph itself. I add vermiculite to my promix bx mix and a tiny bit more perlite to even out the texture.
