Browning of plant 1 lower leaves
Guidance please, On my 1st plant it looks like it has a pH issue however my other plants don't have any signs of a problem. I don't have a pH meter but have test strips and I have not seem an issue with my water. Is the browning on some of the lower fan leaves normal?

Sugar Leaves Turning Yellow
Sugar leaves around top colas have started to turn yellow? No yellowing on any fan leaves. Plants are same distance to light and the environment has stayed constant. Only changed feeding cycle from alternating feeding/watering to feeding,feeding,watering (ppm still the same).

I seem to be having slight yellowing of new growth and some brown spots coming up on the old. Anyone have any ideas what i need to give them? Is this a cal-mag issue or maybe nitrogen? Super newbie and just not sure, thanks! 👍

Black spots spreading // Need your help!
Anyone got a clue what this dark spots could be? It started in a corner of the tent with 1 plant a few weeks ago and now it has spread to another. I suspect pH issues and a nutrient lockout bc of that. Not sure if its the same issue though..Could be an infection as well...

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

Braune Flecken an den Blättern
Hallo zusammen, Ich habe seit ein paar Tagen diese braunen Flecken auf den alten Blättern meiner Pflänzchen. Die Wochen zuvor habe ich gedüngt, allerdings nur mit 1 ml BioGrow, 1 ml BioBloom & 2 ml CalMag von BioBizz — denke eher es ist ein Mangel. Vielen Dank für eure tips!

Need some help asap
What is wrong with her? :( I am assuming N Deficient, but I also have veeeeeeerryyyy lightly burnt tips so it is confusing to me. The lime-greening of the leaves makes me think N Deficient though.. Any thoughts? I have some new nutes on the way should be getting here tonight too.

Got 3 photos. 2 in the ground 1 in 7 gallon. On all 3 the fan leaves and older leaves turning yellow at a pretty rapid rate. Prob losing 15 leaves a week rn. Purp is deeper into budding and not so bad. But should I hit them with a dose of grow big to sort it out? Or no?

Yellowing of leaves Week 9
Help! Is it normal to have such yellowing Week 9? The buds are still green, but the bigger older leaves are quite yellow. Same strain different plant still very very green. Might be the difference between topping an auto and not topping an auto?
