Not sure why but I'm guessing your pH was a little high 2 weeks before this. Ok did I bingo?

sure ill play along, this looks like too much nitrogen at some point or this plant is a very picky eater, either way less nitrogen

Hello, I just noticed that some of my leaves are starting to have slight discoloration and some holes. See images in week 6. I don't see evidence of bugs or mildew and my fan may have been too close for the leaf with holes. I feed once a week and have switched to a high K feed.

Leaf browning, yellowing curl one day change.
Over night my plant went from looking good with maybe a calcium deficiency to curled leaves looking very soft and drooping. I sprayed with insecticidal soap, but in the past no harm. It is growing outdoors, 30c 60% humidity. Any help appreciated. I sprayed with kelp today.

Please look at the leaves shown, orange and dried parts. I asked a similar question earlier but these look more damaged and I'm wondering if it's worsened due to my setup. Wind damage from fans? Water damage from humidifier? Light or heat damage? Managing VPD is tough. Thanks!

Opinions needed.
I have found what Might be calcium deficiency on one leaf near the top of one of my bush’s. but the rest of the bush looks super happy. Could it be light burn?? I feed them cal/mag so I m struggling to believe it could be calcium deficiency.

Is that not enough calcium?
How can I recognise that it is only a calcium deficide? The plant is also the largest and the only one with such deficiencies. Could the plant also be lacking manganese or magnesium and what can I use to compensate for this? Are pests or diseases excluded?

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?

Nutrient deficiency or surplus?
Hi Guys will post a pic shortly. Have to update the grow as we are actually heading into week 6. One of the white widows is a fair bit smaller than the other. And is showing some form of difficiency or nutrient burn. I think it may be due to to little phosphorus. Opinions?

Blotches on Haze Auto leaves (End of Week 8) - Diagnosis?
Could someone look at the last few images of my Haze? Is this a deficiency? What should I do at this late stage? Otherwise it seems okay, other three Autos are doing great. Block would look different? Very crowded tent. Fairly warm 25-30c. Humid 55%. Feeds 600ppm. Cheers!

Any ideas on this?
I'm guessing this is some sort of deficiency. Some of the spots are rust like and occur and young and old leaves. Any opinions? Advanced Nutrients 3 part. No supplements.

I'll just leave this here.
Only a few leaves, but should I be worried? Last few waters have only had calmag to see if that helps.
