Yellow edges to leaves
Hello fellow growers. I have noticed some yellow edges to a handful of her leaves. pH droped a bit today down to 5.6 but has been stable at about 6.4 previously. Photos from the last few days show this problem has been creeping for a couple of days. Any ideas?

Re:
Here's more pictures, and the top 3 inches of soil is dry to the touch before I water again usually. I must've messed up the past couple days or something. I did just add that Mars hydro ts600 though. Light stress?

CalMag or PK issue?
What is she telling me? Before I was thinking of a CalMag issue (upper leafs have "burned" tips and get yellowish). So I added it to the reservoir. Is it CalMag or maybe a PK issue, that resolves in a CalMag issue? See my diary for more details.

Could someone help me to identify the issue my plant has?
This girl isn't looking healthy anymore and I need to figure out why. What I did: I topped her pretty early but she recovered well (you can see it in my grow diary). A week later I transplanted her from 0.5L pot to her final autopot 14L. After that she had a hard time recovering.

Deficiencies? Brown spots, yellowing and purple stems
What is this deficiency or maybe toxicity and whats the solution? She is fed with biobizz chart instructions but with every other watering. She is big so I'm guessing I should water with nutes every time? She showed this first week into flowering.

Possible Nitrogen Deficiency?
Is this a nitrogen deficiency? I had a yellowing leaf or two at the bottom of the plant which have since dropped off, but rest of the plant is looking patchy now. I have just switched from fish mix to bio grow.

Calcium Deficiency ?
Got a little deficiency, can't find what it exactly is. Maybe a cause of this problem is that they got 3 days of nonstop light because I fucked up with the timer just before leaving house for 3 days

Is this nitrogen deficiency or something else?
Hello everyone! One of my plants has some fan leaves and new leaves yellowing at the bottom (and some are crispy). The plant is very bushy but from what I understand this could be nitrogen deficiency but wanted to check. The other plant is smaller and doesn't have yellow leaves

Deficiency?
My current grow is on its 5th week of flower and many lower leaves on each plant have begun to yellow then develop brown spots. I’ve did a little bit of research and I think it could be a nitrogen deficiency. Any help is appreciated.
