supplements and additives for hydo grow

Hi guys
Im currently vegging but will be flowering in next 3 weeks. Im using Gh nutes with lucas formula and thats all. Should i consider buying some cal-mag maybe some clearex for flushing??? does it mattter the brand, for example if using gh nutes is it ok to use clearex or should i use gh lines of flushing products?. some hygrozyme?? heard nothing but good from this supplement.

any thing else i should considfer before placing a order??? i just want make sure i got everything since shipping charges are a bitch.

Thanks, any input is appreciated

look into Zone from dutch masters. it's supposed to not allow algae and shit to grow in your res in high temps...
i'm also using the gh lucas formula (with excellent results). i got some cal-mag a few days ago and it doesn't seem to be reacting negatively. i'm waiting on some hygrozyme (hopefully today!) and i can tell you a few days after i get it if that's all good...

and hey, i've been using superthrive with no negative consequences, and neem oil has worked well for me too (if you require it)
