New Grower Experienced Help needed guys

[Duck Commander]

Thanks guys and muddy, I'm buying some White Vinegar tomorrow to drop the nuit/water down and to also start putting in more water to get run off. I have a new yellow ph pen that reads my tap water at 7.1. That's a good base level to work the bulb with. Some of the plants have no real yellowing, just some of the more progressive ones that are flowering a good'un. I will let ya all knows how things turn out. cheers mike

Be carefuly with the cheap yellow pens of ebay and such they can be far out on the actual PH but you do get lucky with the odd ones that are spot on mate. Also week 6 with the bio bizz blloom you can be at 3ml per L :

This is what I have done: I do not have any pH buffer. When I tested the PH pen from new with tap water it read 7.1. Now it is reading 7.5 pH. (change is seasonal maybe)

Test:Water in :7.5
Test:Water drain off out: pH 7.8

Test:Nutrient solution in 6.5
Test:Nutrient solution out 6.8

Nutrient solution has now been dropped to 6.2 with white vinegar the .3 points needed to hit the 6.5 target.

Any questions please reply.
