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

Starting to yellowSo I had good growth up until 2 days ago when the one plant started to yellow. I had them going 24 hours a day and I got grow dots mixed in the bottom two thirds of the pots. Could this be light stress? or could it be hungry?

What may caused the issuesChecked the runoff and confirmed 6.2PH and 130 ppm on water.
checked on my Tank and same was happening.
so gave a 603 ppm solution of cal/mag. Grow A+B perfect pH connoisseur, H2O2 at 5.8 pH.
Will await for results.
i think at week 3 theyre supposed to eat at least 600 ppm?

Problem in 5 Week of VegetationNow in the 5 week of vegetation. The plants are Tropical Gelato cuttings. Everything was great until recently. They looked great.
After another light fertilization, the condition of the plants continued to deteriorate. Soil PH value is between 6 and 7. Can Someone help?

2 autos with crispy feeling sad looking leaves, how can I help them? (more info in diary pl & crit)2 of my autos have been growing leaves that feel crispy and look deformed. I have been watering when the top 5 cm of the soil dries, but I fear maybe I fed them too much nutrients. The temp has also been on the high side (30C 80F). What could be wrong and what can I do for them?

Lower leaves too pale or yellowing?I am noticing the lower leaves of my Royal Critical Automatic to be much more pale green than the top of the plant.
Is this a nutrient/light/watering/lst stress problem if at all?

Leggy Seedling Recovery attemptPlant got leggy. Lowered 100watt vivosun grow system light. DLI is now at 40 with 20hr on cycles. Plant dropped into final pot so soil could support weak thin stem. Watered recently and leaves got more yellow. On day 4 after recovery attempt. Any advice? PH 6.2-6.5.

Leaf IssuesHey all, my almost 5 week old Moby dick auto flower is starting to show some issues in the first week of flower. She got a dose of Veggie nutes 5 days ago, and a little bit of Bloom yesterday trying to fix it. Temps have been high and humidity low, would that cause this?

Yellow on leavesDay 13 leaves started to look yellow / dull on tips hasn't seemed to improve 2 days later, it is the auto soil premix I'm guessing the roots are getting close the soil and nutes kicking in or does this look like another issue?
