I been growing now for a few months and I made a few grower errors with my nutrient and not testing ph levels as often as I should of been and mostly "topping up" instead of draining and refilling the reservoirs etc..
I made a lot of changes to my grow room and I learn a lot more along the way but I just have a quick question about the pH+ and the pH- that I am using and if anyone know if it is any good or should I be using like a general hydroponics ph kit?

here is the pic

nvm guys I think I can answer my own question. I did some more searching online and people are saying that swimming pool ph contains Sodium Phosphate or a similar compound using those 2 elements which will become toxic to the plants due to the high sodium content.

I am so pissed right now I been growing perfect for a year and I couldn't find the problem to why my yields sucked and why the smoke sucked. and here is it.
 
yea I just placed my order last night for gh ph solutions. so I came to the conclusion if anyone ever encounters a similar problem or makes this mistake and that's in the spa or swimming pool ph products there is no ph buffer. it is a powdered or small ball shaped sand size solids that has a lot of sodium etc.. in it but there is no ph buffer.

so what happens and if your like me half assed most of the time I didn't test my res ph. I would drain and refill with 5.8 every 7-10 days and every other day in between top up with 5.8 water if needed.

now because there is no buffer in these types of ph products my ph would be lets say 5.8 from the start but the next day it would shoot up as the plant feeds off the nutes leaving the 7-8 ph water rise and because there is no buffer to prevent this the ph would remain in the res.

after weeks and weeks and weeks of this the ph will continue to rise and you plant will stop absorbing the nutrients and because stupid me wasent testing the res every other day I was unaware of this.

so lesson learned!

- don't buy shit products... buy the real deal
- test ph everyday and adjust accordingly.
