MediciGradestarted grow question 5y ago
Inflow EC=1333 w/ PH=5.8 vs Runoff EC=658 w/ PH=6.0. Insufficient nutes due to light intensity? Perhaps my PH meter is inaccurate? Light is 42 inches from canopy or ~600 PPFD. RH 65%, Temp 80 F.

everyone says 5.5-6.0, but unless your fertilizer says so, you should more likely stick to 6-6.5.

I agree with Nobody. Your pH is a bit low for soil 6-6.5 has help my girls stay healthy! Happy growing!

While all looking nice and bushy I did notice severe discolor and some of the leaf just snapping down.

Discoloration on new growthBoth of the Sunset plants are showing some discoloration on new growth, one worse than the other. I've been watering very little and infrequently per previous feedback. Wonder if it's a nutrient deficiency. Any thoughts?

Yellowing leaves.Accidentally resolved my original question instead of liking a suggestion and I cant change it 😅
Same issue still applies for now.
I have been testing the PH going in but not out so I will try this and pass on my results after the next water 👍

Leave colors on 3 week old clones blackberry Kush in Coco coir and a jiffy diskSudden yellowing and discoloration of a e or 4 week cutting. I water it when I see the Coco getting a little dry. I make sure there is at least 20% of run off water. I watered with pH corrected water to pH of 6. I also add a small amount of canna bioryzotonic for their roots.

Growing in FFOF with some HF but have nutrient issues...have only given CalMag with RO water and this is what I've got.Wedding Cake nute burn or possible P deficient with yellowing slightly down the edge? Also may have N toxicity with curling leaves? Blueberry also has slightly burnt tips, both plants have yellowing in the oldest growth. All in diary pictures. Thoughts? And how do I fix it?
