Mixing multiiple nutrient programs?

Hey RIU for the longest time I was running some hydro nutrients called X nutrients (Bloom, grow, micro) anyways long story short I cant find that brand anymore locally and online its expensive! So im forced to switch to another line of nutrients. So I started using floranova micro and well fuck this shit. LOL so my question is my plants seems to get burnt-when I read the guaranteed analysis its 15% more then X nutes, so I reduced my per gallon by 1/5th and still am having issues with some plants, others love life? WTF?

15% more of what? NPK total? or just certain one's? N or P or K? If your in hydro, follow the makers PPM ratio's or their feed chart. Same for soil just use every other day and straight water in between. How often are you feeding?
If it was 15% total. Why didn't you simply reduce by 15%?

If you had posted pics this would be easier.

bottle says 5-1-0 guaranteed analysis and im sure its just nitrogen on old was 4-1-0

Also I did reduce by 15% my hydro PPM is like 750!

Yeah the floro line is very dirty too...
I might suggest the Hesi line......The Cleanest hydro line out there!
DynaGro is great....
Canna is great

You say that some seem burned and some are fine? Different strains?
It's very hard to make a call with out pics...

Won't your local grow store order the X for you?

Nope, my local store talked some massive shit about X and then recommended this shit, but I will just have to order online, or find another source

Any other stores in your area? Ask them to!

Yea haha I literally got my veg and micro for like 12 a gallon.......and now its all gone, like they must have really hated the line? lol I dont know, I had great success!
