Hi! im experiencing yellowing and falling leaves in all the strains i planted 5 weeks ago. Only lower leaves. Thought it could be nitrogen deficency but already fed them with N nutrient and still slowly yellowing from bottom to top. All plants are in early flowering stage.
Hey dude noticed this was a Double post I thought I'd put this here to save other growers writing, please see other questions for further information on the issue 😝
Im not being able to stop the yellowing of lower leaves going up. Lowere leaves are diying and the next level is yellowing. A couple of days ago i fed it with N ti stop it but does not seem to work. PH in runoff read 5.9 with 6.5 input water ph. Any ideas on how to stop it?
Since you're in flower and it's pulling mobile nutes up from the lower leaves, I'd guess you need more bloom nutes. P + K + Mg much more than Nitrogen. A 5.9 pH runoff could be locking out some of the nutes too, I'm thinking Mg specifically (which prefers at least 6.0 or 6.5+). I suggest you try feeding it with a higher pH water to get the runoff into the correct range, and see if that helps.
I planted two new honey peach and one is getting already yellow leaves, only trhee weeks old. Its the earliest i have seen yellowing leaves and dont know why is happening. Air temperatures have been high for the last couple of days (over 35 celsius)
