Im having problems with 2 of my ladies, I'm running soil with chemical nutes started bout a week ago and I can not wrapped my head around it. Iv tried to figure out the problem. Iv flushed iv thought it to be a mite problem so iv sprayed with sm-90. Leaves are twisted krinkled some but not alot of burnt tips slow growth as well. Tempature is anywhere from 77 to 83 constantly humidity is 45-55%.who if someone with more experience could please enlightened me many thanks. Will be putting up pics.
Help please.

Id also possibly agree with cal mag. but it seems to be growing on new growtih which means its an immobile deficiency and you said you flushed so if that were the case a simple flush and then following up with cal mag would fix it. what ph are you running? the leaves tent to twist and turn like that when ph is off or heat is an issue but your temps arnt that bad.

pH fluctuation.
Looks like every picture and personal experience. Probably from all the corrections you've made.
I'd get back on track, 1/2 nutes, forget additives, pH to around 6. Watch for new damage or damage on new growth, the existing damage is permanent.

I say ph issue mixed with overferting.. What ppm did you feed her? What was your ph?

I say some thing got spilled on them ?
Running ph at around 5.8 with cal mag aswell with every feeding. Also using tap water that has been sun baked to rid of any clorine. Around 1500 to 2k ppm. I also thought about the ph fluctuations to be my problem. I'm going to try another reflush. I calibrate my ph meter before every watering also gonna try less nutes. I'm running fox farm nutes aswell

Your problem is right in front of your face. You have been going too low on your pH! Soil runs 6.5 veg and 6.7 bloom. Your 5.8 is blocking/limiting uptake of Ca, Mg and P.
Flushing is making it WORSE!
When you water/feed the soil drops in pH around a whole point. As it dries back out it rise's back to it's normal value.
The longer the soil is wet/damp the longer the pH value is lowered and problems begin!
DO NOT flush again!
What soil is it? I have more to add when I know that.

FFOF - How did I know - lol
That's a good soil but, over time I've found (and many others too) that FFOF is a bit light on the Ca and Mg in it.
I like to throw a 1/2 cup of Dolomite lime in per bag - mix well and then run it.
First, let the pots dry to the touch - down about a good inch to inch and a half and/or they feel "light" when you pick them up!
Water when the pots are like this from now on!
Now for those 5 days of pH 7. No nutrients! USE a Ca/Mg that is based on Calcium carbonate and not Calcium Nitrate. The reason is, I want a better pH buffer in the soil your using. The Ca carbonate will be used by the plant just fine and it does better at buffering ... I liked G&H CALiMAGic when I did synthetic. Do this every time you water!
At the end of those 5 days go right back to a veg nute and don't change to a bloom nutrient till week 3. At that point mix veg and bloom nutes at a 1:1 ratio (50/50) when you make your feed solution and use that for 1 week. So then at week 4, you go to 100% bloom feeding...
Good luck!

These are very savable! Start by pHing everything (waterings and feedings) that goes into the pots to a pH of 7 for 5 days and then reduce to 6.7 and run them out.

It'll work but,,not as good a buffer - more of an uptake friendlier form of Ca. That means it benefits the plant more then the soil.
Make a simple bio tea or get some living mycos in a liquid form and add those.....do this at least once a week as they will help your plant set the pH and hold it.
