Yellowing bottom growth

UncleOrganic95started grow question 4y ago

Noticed some yellowing in the older bottom growth, any idea what this may be? I'm thinking my pH meter is off or deficiency, not sure though.

Hmmm tricky one could be her shouting out for more nitrogen as yellowing on the bottom leaves going up usually is nitrogen I would try giving her half dose of your veg feed and seeing how you go I think it maybe too late for that leaf but it should stop the plant consuming anymore :) Best of luck overall shes healthy so good job.

Might be calmag deficiency. Look at your mars hydro instructions and see if it says anything about using Xtra calmag. Mine kinda looked like yours in a previous grow and calmag fixed it in days. Advanced nutrients sensi calmag has abit of nitrogen in it too. And Advanced nutrients rhino skin. Or any brand that is silica is really good too. Check out calmag deficiency photos and see how the leaves go weird blotchy yellow. I use calmag and silica in every watering. Just lower dose than it says.

Yellow leaves from bottom upwards I have yellowing leaves from the bottom up. It resembles either N deficiency, MG deficiency or both. Growing in soil. PH is between 6.5-6.8. Feeding 1ml/L fish mix and 3ml/L bio-bloom every other watering. I tried adding cal-mag with N at 1ml/L and if anything it's got worse.

Scared of bud rot So my last harvest last week had bud rot and I noticed my Royal jack has a lot of yellow leaves but I think she still needs at least one more week to grow. Could this be bud rot even if I don't see any other signs? Should I do an early harvest just to be safe?

Yellowing leaves help please (newbie)Hi guys, had a calcium/ magnesium deficiency last week which I have treated with calmag this week However I’m concerned the plant is yellowing more. Is this still related to the same issue ? I understand the brown spots won’t be reversed but should the leaves still be yellowing?
