What is happening to her?
I noticed a few stains starting to appear. The old tips are kind of burned and the new are a little yellow. I fed her with a compost tea but with nutrients on it, maybe was overfed? Could be PH issues? It's possible, I couldn't take the ph on the last two times I watered her.

Yellow lower leaves
Guys/girls please help! Lower leaves have started getting yellow. I really don't know the issue. Is it of nitrogen deficiency? A lot of you have told me that 4ml of fish juice is a lot, so is there a possibility of nutrient burn? How can save her?

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? 😳

Discolouration of some leaves
Is the colouration of these leaves someone to worry about? She’s a young, 2 week old Wedding Cheesecake auto and I’m new to growing and just want to make sure she’s ok! She’s growing in a 70/30 split of coco and soil and has only been fed water so far! Is it nute time?
