New Grower MCPD_Refugee loses his virginity to White Widow and Blueberry

@Z_Bop...don't worry, brother. You didn't steer me wrong. There is no need to apologize. You weren't around when I made the bone-headed decision to buy Fox Farm soil knowing damn good and well that t was hit or miss.

As for your advice, I still don't have a pH meter yet. However, In addition to the Accurate 8 soil pH meter, I also have a pH pen on the way thanks to your suggestion...so it's all good.
 
... no need Z_Bop, it is a good example of how cumulative inputs can drive the pH down, along with up'ing the ppm's/EC,.. one thing that can bite back before too long! Finding "just right" on that is no small thing,... one reason folks like to go organic, where the cumulative inputs form synthetic nute salts isn't an issue,.... :thumbsup: to give you an idea about how different pH availability is between soil/soilless and hydro', check out these charts-->

-- great! If you weren't in bloom, foliar spraying would be a good way to go for fast results, bypassing the soil while you get that dialed in,,, but mold and residues are an issue during bloom, so that's out for now,.... try that water only run-off pH reading, it can offer a clue at least... a TDS/EC reading too if you can,...
 
@Waira, I've got my pH pen and my soil pH meter. The soil was reading 6.5. I mixed a fresh batch of nutes using distilled water. It measured 6.5. I'm at a loss here. Could it just be a serious Cal/Mag issue? I'm at 2.0 mL/L at the moment. Should I up it to 2.5mL/L?
 
Day 39

Things are chugging along. The Blueberry looks to have either a potassium, calcium or magnesium deficiency. I cannot tell. Maybe someone can ID it. In the attached photos, there's a close up of a leaf. Have a gander. Let me know what you think.
