New Grow

Alright I just went out and bought PH up and down but couldn't find test strips. Its SPA ph up and down and is made up of sodium bisulfate and sodium carbonate, are these chemicals ok. Also if the plants are only a five days old is it ok to hold off on the PH adjustment of the nutrient solution for a few more days since I cant find test strips anywhere. They are currently in rockwool and are getting wattered 4x a day.

Thanks guys

from what i know their are test sticks which are more resusuble. Only one and you keep it for life. well i got mines for less then 5 bucks. the strips cost about the same and then you need to keep then dry and you can finish them using over and over. Let stop doing shoot like that let save the world lil by lil. After all if it weren't for the world we wouldn't have bud delicous buds... good luck bro...
