According to your log your pH is a bit high.. this can cause a lockout of iron which it looks like what its doing.. shoot between 6.0 and 6.5 if possible! Cheers and happy growing!

Yellow leaves below and some others
Guys, I have this 6 week old baby with some yellow leaves and others (lower) completely yellow. What can it be? I have been using Biobizz Top-Max, Grow and Bloom in small doses as described in the diary. I looked in the deficit chart but couldn't find any answer by myself.

What do these yellow markings on the leave tips mean?
What do these yellow tips on the leaves mean? Are my lights to close? Looks like light burn to me and have adjusted the lights up 10cm for now. Still wanted to make sure since I thought they need more lights during flower. Thanks heaps

The leafs started to look yellow in the middle when I checked on them today. They looked fine to me yesterday so I guess this happened in the past 24-48 hours, not sure why. It can be seen on Day 12 pictures. Is this normal or I should be worried?

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?

Nutrient imbalance or healthy development?
Are the colors of the leaves a sign of healthy development in the flowering stage, or a sign of nutrient deficiency/excess? After struggling a lot with the nutrition of this plant, I am not sure anymore whether I'm doing it right. Some of the leaves become yellow and fall off.

Wilting and yellowing leaves after vinegar water solution
I sprayed a mixture of 1/4 spirit vinegar + 3/4 water under the leaves to get rid of aphids (which may or may not have been the problem) earlier today. Now checking on her, I see yellowing of several leaves and wilting of others, which has me worried... normal, or a problem? 😳
