HELP - FLOWERING PLANT SLOW DYING BY BURNING =(

Nuke burn you fucking meathead . Correct it . Or your grow will be trashed

thanks guys! I'll buy a ec meter to check these stuffs. I was used to use the same recipe for them, so I was thinking that is strage that when I change the label of one nutrient the plant gone bad as that. I'll flush them for a week and then back to nuts, mesuring the ec. So i need to get low on Potassium, correct?

Man you are only burning your plants due to excess of salts in the medium. 100% sure!! Check the runoff ec , is a must check the ec !! Go with a heavy flush mate and then give way leeeeess nutrients

What Roberts said, it's potassium.

I had uploaded some photos to u check how this starts at some plants, then this burns in the tips slowly starts to grow, and the tips starts to die. Those plants already have 5 weeks in flowering, and I know that i must to something soon because this will difficult the photosinses for them, and as consequence I could have low yelds. So friends, help me to do what I should do. I'm trying to find some Calmag nutrient to replace Calimagic (general hydroponics) but as I said in Brazil is very difficult to find similar nutrients, and I'm trying to get new one, but the formula of them doesnt match the formula of Calimagic, so, I believe this is what are causing this. Im using CalBorMag that is a shit nutrient, that give me boro in the mix too, and I dont need more Boro. So i decided to change to Remo MagNiFiCal - but the Remo has less Calcium and more Magnesium than Calimagic, and has 3% of Nitrogen too, so I could fuck up the plants using him, but I'm having no option, maybe put less MaxiBloom in the mix, to compensate with MagNiFiCal, what do u think guys? Since I was run out Calimagic my plants started to burn at Edges - I'm blooming LSD - Barney's Farm . Ayahuasca Purple - Barney's Farm . Skywalka Cookies - Big Head Seeds . Ak Cookies - my own genetic, I crossed one Cookies Kush with one AK 47, and did it well. So, the LSD start to burn at first, and weeks later some of them presents some points burned (as you can see in the picture, i post some pictures that the plants are fucked up and some pictures that the plants are just starting to get fucked ) . Please friend, i'm very upset because i'm trying everything and nothing get's well. I already did 3 flushs at them, measure PH several times, now changing the nutrient that I was thinking that are causing this problem, and still not solve at all. It's difficult to note if they are getting better because the fucked up leaves doens't will turn back into gourgeos green leafs, i'm having a bad time over here and any help would help a lot .
