Help me confirm this Calcium deficiency diagnosis?
val95started grow question 3y ago
I'm not quite confident in my ability to diagnose this using the charts you find online. Can someone confirm this auto in DWC (pH=5.68) needs some more Ca?

Looks like it to me, but I also see some leave affected by pH going out of range. Try bringing the pH up to 6 and see if that stops the Browning. If your pH gradually goes up then start at 5.8 and correct it back when it reaches 6.2. if your pH gradually lowers start at 6.2 and correct at 5.8. This will ensure your plant hits all pH ranges to absorb everything.

Possible toxicity or deficiency?I saw this on one of my bottom leaves this morning. Hopefully someone can give insight of what it might be. I'm concerned that it is phosphorous deficiency. I didn't notice it a day ago, but I wasn't looking closely. 2 days ago I watered her (540 mL, 1/4 tsp nutrients). Thoughts?

If my ppm intake is about the same as my ppm runoff but my pH runoff is way lower than intake should I be worried? Or what should I do?If my ppm intake(705) is right about the same as my ppm runoff(790) but my pH intake(6.7) is off from my pH runoff(5.9) should I be worried or be trying to correct something or should it be fine?

Add CalMag or Manganese? Still slightly discolored and veiny leaves on week 6Calcium or Manganese deficiency? Last week had what I thought was early calcium deficiency. Gave it a dose of CalMag but now not sure if it’s still Calcium or possibly Manganese.
I do mean manganese but I realize it could be a CalMag or Manganese deficiency as well.
