Looks like you may need to add a calmag supplement to your feeding program mate.

Yellow spots on leaves
Hi Growers! First grow here and I'm concerned about new yellow spots on my lower fan leaves (one tip is dark too). Soil is Atami Kilomix, heavily fertilized. 2 days ago only one leave was affected. What can it be? Mg def? N def? P def? N tox? Too less water (100ml every 2-3days)?

On the 31st day I noticed that, in both the plants, the leaves started yellowing from the bottom of the plant! For now the yellowing reached the first couple of fan leaves. You can see that in last three photos. Could be some pH issue or some over/under feeding?

First grow yellowing seedlings :( nute problem?
I seem to be following all the instructions on grow temperature range, light distance, and watering schedule(only watering hen the medium is drying); I've hardly used any nutes until day 22 as advised and I personally think this has caused me some issues although I may be wrong.

Mid flower flush
Hey guys :) Have you ever done mid-flower flushing and if yes, how did it work out? Gonna let the soil dry completely and then water nutes again. Could the pH being buffered to 7.10 (shit soil) be the reason for the yellowing leaves or does the plant need more or less of somethng

Probable phosphorus excess nutrient block
Hi, I was wondering how long are the nutrients blocked after an overfertilisation ? I lowered my EC to 1 (day 24) since they are growing a 3rd internode. Thanks !

Yellowing sugar leaves?
Does this yellowing on the sugar leaves look problematic? I know the end is near so I don’t want to do any damage this close to harvest. Think another week will be long enough? Vermiculite/Perlite/Soil @ 40-40-10% Lotus Bloom @ 1/2 dose (700ppm) 100w LED 14” above canopy

Possible calcium def. or other issue affecting leaves and buds
Is this a calcium issue, and if so why is it spreading to this one bud in particular? There are four photos of the effected bud, as well as a few shots of unaffected buds to compare. Also have spotted leaves that look like ca issue but not sure why its spread to the one bud.

Bottom leaf turned yellow with brown on edge
Hello this is my first grow and had noticed a leaf turned yellow with brown spot on the edge. This is a northern light auto just kicking off with her flowering. I use advanced nutrients 3 in 1 micro grow and bloom and that's all I've ever used. I suspect a nitrogen deficiency...?

What is this rust discoloration on leaves, and how can I stop it?
Does anyone happen to know what is causing this rust colored discoloration on fan leaves? It starts on bottom leaves, and moves up. Also seeing yellowing on leaves, and not sure if its pest issue, light issue, deficiency, or watering concern. Super nervous plants are dying🙁
