Yellowing of the lower leaves during flowering is quite normal/common, but either add or up your P/K booster to help your plant, she will be hungry for phosphorous (P) and especially potassium (K) during flowering.

The damaged leaves won't recover, but it will prevent the other leaves from suffering the same fate.

Yellow and purple leaves
I stopped feeding beginning of the week because I had yellow tops on one of my buds. I think it is causing yellow leaves. Does that sound correct? Also I am seeing sort of a purple colouring on some of the leaves. Is that okay?

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?

Seedlings going yellow
Could yellowing of leaves on seedlings be from too much fertilizer ( liquid fish, compost,seaweed type.) I wouldn't suspect iron deficiency as it is new premium potting mix that they are planted in. I did feed with about half strength liquid feet about 5 days ago.

Feeding
How often am I meant to feed and water my plants. I do water my plants every 3 days and after every three feeds I flush. Concerned as all the bottom leaves in my grow are turning yellow but the tops are okay. I do give them Calmag so I’m not sure what the issue is here.

Yellow on leaves
Day 13 leaves started to look yellow / dull on tips hasn't seemed to improve 2 days later, it is the auto soil premix I'm guessing the roots are getting close the soil and nutes kicking in or does this look like another issue?

Leaves turning yellow/pointing up, stem turning purple
Having a problem with one of them.. all the leaves have gone very yellow and are pointing upwards. The stem is also very purple now. Any ideas what this could be? Other than a feeding of bud candy and watering here and there it hasn’t gotten any other feeding. Thanks!
