Yellowing leaves on young plants
Not sure why the plants are yellowing at the bottom
I added some calmag thinking it maybe a nutrient deficiency

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

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.8 months ago

Too Much Light?Top looks yellowish, more so IRL than in the pic and the new growth is kinda taco-ing. Just under 24" from the light, 78F and using Photone the DLI was at ~30. I don't really trust that app but if it's even sorta accurate, 30 might be high with no CO2? says their charts anyways.Leaves. Curl up

Please help identify my Problem: Yellowing leaves with veins showing and some necrosis spots in third week of flowerThe odd thing is that only some leaves in the middle of the plant are affected. My thoughts were Nitrogen or Manganese deficiency or maybe light burn (why in the mid of the plant tho?)? I feed Biobizz Bloom, Grow and TopMax, no Problems until now.Leaves. Veins - yellow between

Week 8 (4 weeks into flowering) - Possible Nitrogen / Cal-Mag issue?Plants show signs of what i assume to be a deficiency. Stopped feeding nitrogen Week 7 according to schedule. Symptoms are not on every leaf but some the upper foliage. Yellowing, burnt tips and rusty spots. My guess is lack of Cal-Mag & Nitrogen. Is my guess correct?Leaves. Tips - Burnt

Yellow tips at bud-leafsWhat is the worst case of what could happen to the buds and the harvest due to the yellow tip burn?
Since 5 days the near leaf buds have yellow tips.
It could have any reason. Flys, high ph, to high nutients.
Already watered with neem oil and gave citrusjuice in water to lower p8 months ago
