Low PH runoff, dealing with deficiency due to low soil PH. Added lime and PH went from 5.4 to 5.0 after watering. How to raise it safely and quickly?
I have been dealing with a nutrient deficiency so added nutrients.It looked ok but then got a bit worse and I took some runoff readings which were 5.4 and then 5.0 the next week after adding lime to raise soil PH. How can I best raise the soil Ph being that I added lime already.

Organic grow Ph/ppm
This is my first full experience with organic growing. I would like to know if measuring ppm/EC of the substrate at the output makes sense? And why does the pH rise so rapidly over three days?

Bottom leaves yellowing over last three days. Day 15 of flower.
My bottom shade leaves have started to yellow. I am just starting 3 week into flower. Am I having a nitrogen deficiency or is this the normal yellowing. I just started a very light 1-1-2 nutes in my water to supplement. No nutes until now except in soil. See pic

Seedling Help
P3/P4 in my active grow seem like they are missing something. Any ideas? PPM of 300 with SLF100, some Great White, and Recharge in 5 gal of dechlorinated water, PH 6.47. Might want cal-mag?

Nitrogen Toxicity?

CalMag during a flush?
I was wondering whether or not I should keep feeding CalMag while flushing the plants. I've read a lot about the flushing process but since CalMag is not considered a fertilizer, I am not sure how to handle the deficiency at the end of the grow. Any tips? Thank you guys!

Blotches on Haze Auto leaves (End of Week 8) - Diagnosis?
Could someone look at the last few images of my Haze? Is this a deficiency? What should I do at this late stage? Otherwise it seems okay, other three Autos are doing great. Block would look different? Very crowded tent. Fairly warm 25-30c. Humid 55%. Feeds 600ppm. Cheers!

Should I remove foliage affected by deficiency, or just let it ride?
Autoflower started showing sign of deficiency at week 8. Assuming CalMag, as I filter my water and affected area is new growth at top of plant (see pic). 1) Can someone confirm CalMag deficiency or something else? 2) Should I remove affected leaves or leave them be? Thanks

Deficiency or ending cycle?
Hey! I was hoping someone could tell me if the first plant has a deficiency you would recommend I correct or if she is slowly coming to an end of her life cycle and I should just let her fade? The last picture is my other plant, less severe, but same question :) Thanks!

Help needed - harvest time?
Hi, I'm now in week 12 and I feel that after the flush my 2 vertigo stopped developing. They also have a lot of leaves with some mag issues. Not all the pistols are amber (70%). Also, the trichomes are not all cloudy. I'm not sure but I think I don't see changes anymore.

Discoloration on leaves. Why?
I was looking at a closeup view of an overhead pic I took yesterday and noticed some slight tan/bron color along the sides of the 2 bigger leaves. I'm wondering why. Nutrient burn? Sulphur deficiency? Something else? Any thoughts?

Can this delay flowering of an auto?
What deficiency is this please? I suspect phosphorus deficiency and as such have reduced the PH from 6.4 back down to 5.8 It is not spreading and appeared spontaniously and at once a few days ago. Growth has been slow for almost 2 weeks and flowering has refused to initiate.

What nutrient is causing this?
I know for a fact that it is some kind of nutrient issue. I’m not sure what but that’s what makes the most sense. Because it ONLY shows on very early growth and then disappears as the new leaves continue to grow. I’ve been through very cold weather and never seen this.

HELP—Trained eye needed for a nutrient deficiency diagnostic!!!—HELP
Can anyone help me with diagnosing what appears to be a nutrient deficiency? I used Jobe's fertilizer sticks (13-4-5) [I know, horrible stuff but its all I could get for the next two weeks] which I diluted to 1/8, 1/4, 1/2 of the recommended amount as per label. CHEERS!
