Deficiency?

Hi,I'm having an issue with my current grow and I'm stomped. Full transparency, I'm running hp pro mx and down to earth slow release amendments,tap water. The soil ph is at 6.8. I've also ran the this same batch of hp pro mx with a different nute regiment and the issues presented the same way. The only Nexus I've found is it's the same strain and media. I'm not as experienced as some of you gentlemen here so I value your input. Leaves are curling down with tip burn.

We need a little bit more info like what your environment like, what temperatures and humidity and what light you use and at what distance to the canopy? You should dial light intensity way down starting a organic grow since it takes time for the nutrients to become accessible to the plant. If the plant doesn't have enough nutrients and roots and being bombarded with light intensity it will stunt growth.

First cause of action with any plant stress related issue is dialing down light intensity while keeping the environment in check.

They are getting 300 par and the temp is 82 and humidity is 75

How do know your soil is 6.8? And your reusing it with slow release? My impression is it's pH related. Either the peat dominant mix has exhausted its lime buffer or your ammendments are causing the imbalance. Organic amendment commonly acidify before they neutral out. This is 1 reason why ammendments that are incorporated need to "cook" for 30+ days. Top dressing is a little different.

Whats the pH of the tap water? Any known mineral content and their values? Water quality and values do matter when your reusing substrate.

I was asking what kind of light and at what distance not a par reading that may differ depending on instrument? Focus on the plant response not numbers starting out.

What footprint, type of light and wattage and distance to canopy would help to better diagnose. Also how much they're being fed and how often?

I will get you that info ASAP because I'm not 100% sure. I've had these lights for a few grows and never experienced this.

I didn't reuse the substrate,it just came out of the same bag,as far as cooking,it's been sitting for 2 months. I've turned it at least twice during then.

I'm not sure if two month sitting with a rolled up top is "cooking", but ok.
Cooking is maintaining and monitoring pH and moisture content, along with temps. Starting, peak and finish.... if you want to get down to brass tacks.
 
Sorry should have been more specific. Describe your process of testing your media
Insert the probe to make the hole (cap on) then remove the cap and insert the pen,turn on. However I did notice that my hydration solution was kind of low. Even though I calibrated it, the manual recommends letting it hy hydrate for 24 hours which I did not do. Just to be clear,I appreciate you gentlemen and believe it's a 100% me fucking something up. I'm gonna rehydrate the pen and get back to you gentlemen,thank you in advance!

It's a 5 part, veg a@b boom a@b and sweetener
That's a problem, especially with amended substrate. You treating your soil like it has a bio machine full throttle, when it actually doesn't. That's due to the raw ammendments you added.
My suggestion.... add your raws and cook it first. Then IF need be, supplement with a boost. Cannabis damn near grows itself bro. It doesn't need much to sustain, give it a hair more.... it excells, give exactly what it needs, when it needs it and force it down it's throat, .... perfection. Don't kill with kindness. Less is actual more. The plant actually has an internal EC within its tissues. If your soil has more than what the plant does.... it's similar to a magnet. Pulls out and blocks the uptake, but if the plant has the advantage and the soulmis supplemented based on needs, well.....

The sweetener is only accelerating your microbial biome, and if the plant isn't up taking, your going to cause an imbalance, mother nature does what it does, based on influential factors. Add sugar, and your gonna have an increase in microbial enzymes and nutrient assimilation. Factor in a plant that isn't developed enough to handle that increase, equates to a less than desirable upon observation. And environmental factors play a HUGE ROLE in manipulation of plant response and biological activities within.

If I were you, I'd pick one or the other. Organic or mineral salt. Playing a card game without knowing the rules doesn't equate to a guaranteed win. You've got 2 different mechanisms of delivery

I didn't do this with the slow release,this was a separate post in which I used pro mx right out the bag,no the one I had mixed.
