Toxicity or deficiency?

[Purple Lemonade]

Hi im trying my best with ph ppm and so on. I have 5 more which looks pretty OK but these ones looks like ij these photos. Im using advanced nutrients with full line including grand Master ones.

There are 4 plants with problems which i numbered them in photos. Can you please help me identify what's wrong with em? Should i flush or give nutes?
Thanks

How often are you feeding nutes? I’m guessing they’re heavily over fed, but grow details are needed for anyone to help

I give them half dose of recommended once per week. Not so often :/

What kind of soil are they in, how many bottles of nutes go into a feeding at one time? I’m not familiar with that line of nutes. Do you have anyway of checking ph after you add your nutes?
Some nutes can be very acidic and ph may need to be adjusted

What is the ec of all things combined? My experience is less is more and most deficiency problems are actually due to lock out from over feeding. When you use a comprehensive line of nutrients then there's no way anything is deficienct and I've yet to see s deficiency which actually was a deficiency. If your ec ever goes over 180 then you're playing with fire.

Looking at the photos they look burned from too much of something, use something like,canna flush to break up and expel the salts. The more nutes you add the worse it'll get I promise you

An EC of 180 would burn the planet down
I'm assuming you ment to say 1.80

Too much accumulated salts. I'm going to assume the mix is peat dominant. Peat has a high CEC and tends to hold onto nutrients.
With peat based soils and using bottled salts, it's always best to feed, water water feed. This way the plants have a chance to take in the salts before they accumulate to levels of a lock out.

What type of light do you have, wattage and height from tops?

Yeah man, you knew what I meant though with the ec lol! The first thing any grower should do is ignore the doses recommended by manufacturers and realise that they really don't need stupid amounts of feed

I just started adding plain water between feedings.

If your close to your harvest window, just let them go. You can just give them plain water from here on out.
Otherwise if the harvest window is much longer, you can flush. Plain water works for this.

General tip for anyone - if you use an ozone generator be very careful where as the ozone is great for smells but terrible for your plants.

Just flush them. If you used the full line then it's unlikely they are deficienct of anything. Flush them. If you can get some canna flush it's only cheap and it breaks down salt build up. I promise you they need flushing not feeding

I bought canna flush with your recommendation but usage is too confusing.
Am i gonna use 2ml/L first then water it with to water after ?
Or give it and let it sit for 24 hours ?
I scanned through all internet but couldn't find an exact answer.
Am i gonna ph canna flush as well too or no ?
