T Rex nutrients Thailand any good?

The only brand nutes that I know that I can find here are Advanced nutrients and Fox Farm trio and they cost 60 bucks and up for a half litre set, not in the original bottle, no way to tell how old the nutes are, etc.
There is also this local brand T-Rex, that I guess fashions itself after Fox Farm Trio with a three bottle set, but I have no clue about the quality. Are there growers from Thailand that can give me some insight on these nutes?

Is this organic or do you have to PH the water? Is it good? Does it burn plants easy? Dosage? Link to a feeding shedule?

Thanks!

Stuff looks legit but no feeding schedule to be found. Website not complete despite them being around for a while. Just use the bottle recommendation at half strength to start.

Thanks chief, but I'm looking for people with hands-on experience.... Nobody?
