Yellowing leaves, some spotting
Hashyanswered grow question 4y ago
Could be it wants a bit more nitrogen. Your balance is 4-4-4 so you could use a calmag nutrient with more nitrogen in, a lot of cal mag products have 2-0-0

Yellow tipsDont know why but one of the girls is suffering from stress. I think this is the cause for the yellow tips or do you have a other opinion? I did LTS training every two to three days, maybe therefore?
A other reason could be light burn. But with a distance of 50cm I dont think soWeek 4

Top leaves are yellowing in flowering-Is this Nutrient deficiency or excess or lock out?I am growing 3 Auto's.
One of the plants seems to be much more affected than the other one.
near harvest/Cloudy Trichomes no amber
I just gave them all a feed with the recommended Fox farm nutrients which is twice the concentration they normally get.
Any ideas?Leaves. Color - Yellow

Yellowing on lower leaves. Any idea what this is?Don't think they should be deficient in anything yet, they're in new Ocean Forest soil and only on day 11 of veg, no way they used up what's in the soil yet.

Cut off yellow leaves.Can I cut off these leaves?
I am worried that this is an autoflowering plant and it will be an additional stress for it. But it also seems to me that it is spending some effort to keep these leaves alive and it would be better if it spent this effort on the buds.Week 5
