Nitrogen starts yellowing at the bottom, if you have abnormal growth or yellowing on new growth it would be calmag.

I can't see it clear on the photo. Make sure the PH pen is calibrated, also take a look at the new growth after you added the Calmag

Most likely nitrogen deficiency. I know nothing about hydro though, feed needs increasing if it's draining the leaves. It's basically eating itself to survive

Issues with leaves. Day 90 total, 30 of flower. Leaves have been getting more and more yellow the past week, with progressively more brown tips.
Vpd has been pretty close to ideal, the pot had 1 gallon less soil so could be missing out on some nutrients? Possibly Potassium? Otherwise not sure what it could be. Does not appear to be N deficiency because the leaves are affected from the top too. What should I do to fix this

Yellow tips
Dont know why but one of the girls is suffering from stress. I think this is the cause for the yellow tips or do you have a other opinion? I did LTS training every two to three days, maybe therefore? A other reason could be light burn. But with a distance of 50cm I dont think so

Why do my plants only have that light greenish yellowish look at the top and why is one of my plants also having those sick leaves at the bottom?
2 of my 3 plants are a bit yellow-ish at the top since about a week. Plant 1 also had a couple of sick leaves at the bottom that I did remove. Those leaves had brown/dark spots, felt dry like paper, had very purple stems and did smell more like hay. More info in my report.

Newer growth is lighter in color and thicker than the other leaves. She was under my humidifier so maybe drinking too much? Dry organic amendments so no additives in water. Several other grows in same feed schedule and no issues

Can someone tell me what is this? I think the reason is that my nutrients are not balanced but I have no clue what deficiency this is, It could be so much easier to know the reason for this if I know what this is. pH pretty stable 5.8 Ec 1.5. Thanks!

Does anyone know what this is? Just before this happened the leafs were cupping upward. She’s in coco coir and perlite. I feed her biobizz grow 3ml/l and biobizz heaven 4ml/l and cal mag 1ml/l and ph the water to 6.3 about 6-7 weeks into veg and this is the first problem I’ve had
