Yellowing weeding cakeStill having a issue 5 days into flowering and my wedding cake has gotten very yellow looking. It hasn’t seem to slow down any but I’ve also applied some nutes yesterday but not heavy as I’m swapping over from veg nutes to bloom. Any advice? I moved fans and lights 18”+

1st grow yellow leaves and brown spotsLast two days some big fan leaves started to get yellow with brown spots. Im half way through flowering stage. Is that normal? Can it be nutrient deficiencies if some of these leaves are on top?? It's not overwatering for sure, I'm puzzled :(

Am I taking the correct steps?I think this is due to a combination of overwatering (1l per 24 h in 60% Light-Mix, 30% coco, 10% perlite) and possibly overfeeding (used close to recommended dosage). I have let her dry out for almost 2 days and today watered 0.5 l plain water ph-ed to 6.5. What do you think?

Strange yellow patchesThis is a new one for me, sont think I've ever seen discolouration like this before. My first thought was having left some nute solution on her leaves after feeding but pretty sure I've ruled that out and more leaves have begun to show the same discoloring. Any advice appreciated

Leaves with yellow spotsWe have find some leaves with yellow spots in them. The tips on new leaves are also turning yellow. Is this nutrient burn? Searching online I found it may be due to pH fluctuations, although we use pH controller with ferts (before ferts only bottled water pH ~5.5).

Is this Stating something or is it paranoyaI had a few leaves that were turning yellow, but they are lower leaves that are slightly yellowish on the outside, generally the plant has become a little lighter since it started flowering.
Am I worrying too much?

Brown/yellowy Spots and StripesAlright, last night I did a reservoir change. I added a fraction more nutrients to the water (.25ml per gallon). I also topped the plants. This morning I woke up and there were these brown/yellow spots and stripes on the leaves. Any idea what it’s from?
Thanks!

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 so

Bottom leaves yellowing in floweringMy lower leaves started turning yellow and drying out, am I having nutrient deficiencies? My guess would be nitrogen or potassium but not sure, had some nutrient burning earlier so cut down on the feeding a bit.
