Help to Identify Possible Deficiency

pH = 5.9
Nutrients: Cal-Mag (1st time this evening)
Timeline: 21 days / Indoors
Strain: Critical Purple

Hello Everyone. I’m new here and new to growing. Can you please help me identify if you see a deficiency? I mixed earthworm castings into the soil and I’m using distilled water.

Thank you!

In soil your ph should be higher. The 5.9 is a good ph for coir or hydro. Your target should be 6.3 to 6.5

In soil, you’ll want your pH between 6.3-6.8, with the sweet spot being 6.5. In soil, Calcium doesn’t get taken up properly if the pH is under 6.

Distilled water doesn’t really have a pH on its own. Before using it, you still need to adjust it for the plant. Growers use distilled water for its absence of stuff (low ec/ppm), not necessarily its pH.

This may seem counterintuitive, but at your next water/feed, adjust the pH to 6.3. Then carefully run enough through your pot to get about 25% run-off and checks its pH. If it has fallen to 7 or lower, then good, just keep proceeding with watering/feeding as usual, BUT ADJUST YOUR PH EVERYTIME.

If it went higher, you’ll need to do a real flush with pH adjusted water. Depending on your nutes, this is necessary about midgrow, anyway, but you’ll want to flush the pH to its proper range asap. Anything above 7 is absolutely too high.

The worm castings drove the PH up above 7 IMO. Good stuff but might be better in a “tea”.

What EXACTLY is your soil?


I meant to ask that, too. Plus pot size, for the possible flushing.
