Burnt tip deficiency?
On every grow I see this same deficiency, it doesn’t appear on new growth. It normally appears on older leaves sometimes from the node right before the new one and lower on the plant. I’ve feed cal mag 5ml all the way through. I was thinking it might be sulfur but not sure.

Help! Sick looking plant
Hey! My plant has been looking really weak for the past 3 days. Can't figure out if it's a PH problem or a nitrogen deficiency. Any tips? Thanks 🙌

I've been getting some of the burnt tips as a result of the watering with nutes. The nute mixture is already half the recommended dose. I've tested my runoff pH and its about 4 or 5 even though I've been pHing my water to be around 7 and no lower than 6. Anyone have any tips?

should I be worried?
I have a problem identifying the cause.I notice that the lower leaves become dry, crunchy lose their color. But only the very last leaves at the bottom. I do not notice any problem towards the apex. Does anyone have a lead please? An excess of P ?or K?

Burnt tips and yellowing leaves
About two week ago, lower leaves started yellowing, and I saw burn leave tips, so I suspected nutrient burn. I only watered with tap 6.5 pHed water since, but the burnt tips and yellowing are getting worse continuously. At least 3 largest lower leaves died off over the period.

Yellow Cotyledons?
NLxBB was born with yellow cotyledons. The shell was stuck after sprouting so I had to help remove it. Took around 2 days before I saw them barely open with new growth. The new growth is green and seems healthy. Is there any reason why this is happening?

Soil pH is surprisingly high. What's the best/safest way to lower soil pH (without eliminating nutrients from dry amendments)
Granite Runtz #2's leaves have started to lighten in color & develop rust spots/mottling. Troubleshooting this, my soil pH is in mid 7s; I always pH water to 6.4-5. Will daily watering with ~pH 6.0-2 be enough to lower soil pH sufficiently? I wonder if this also affected growth?

Strange yellow patches
This 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

Tips turning yellow
The tips of the leaves are getting yellow. What does it mean? And what can I do about it? I just replanted her a day ago. No nutes since then and not much before that either. I attach two photos: the first taken today and the second - last week.
