A few of the leaves started to get yellow spots along the veins. I was pretty sure it was nitrogen deficiency so I upped the nutes a little. Over the next day or so, 2-3 different leaves started to curl down at the tip. Is this too much nitrogen?

Seedling getting too much light?
Is my 6cm tall seedling getting too much light? I downloaded a luxmeter app and for front/back cameras, it reads 4000-6000 lux. I'm worried about the light green veins. Is this normal? First grow so super unsure what everything is supposed to look like. Light is 18cm from plant.

Please help identify my Problem: Yellowing leaves with veins showing and some necrosis spots in third week of flower
The 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.

Leaf issue
What seems to be the issue with older and new leaf growth here? It looks like cal-mag or potassium deficiency in my opinion, but I’m not really sure.

Yellow streaks between leaf veins
All three of my plants have light green/yellow streaks in between the veins on the leaves that have been present since about week one (week 3 currently). Could this be a magnesium nutrient deficiency, PH issue, or perhaps just overwatering?

Magnesium deficiency?
Can anybody help with the yellowing between the leaves? Is this a magnesium deficiency? The leaves are still pointing upright but do have slight yellow/brown tips. Have recently transplanted into coco with an EC of 0.56. Ph was 5.8 and runoff was 5.7 when last fed. Any ideas?

They are on the older leaves and they keep getting that faded yellowing starting from the tips. The pH of the run off is 6.43 and they havent been fed a round of nutrients in a week! I thought it was a cal/mag def but they haven't bounced back after a dose. Help please!

Cal or mag def?
Believe this is a cal or mag def. Didn't begin supplementing until last week (2ml organic cal-mag per gal), but they're getting it w/ every watering now. Lightening between veins on higher sites, minor rust spots on lower sites. Think I can ride this out,but wanted to hear others

Hi, im having some troubles with this little girl, there is this yelowing around the edges on some random fan leaves and smaller bottom leaves. I am not sure what is wrong since all the other plants are growing well under same conditions. Could it be magnesium deficiency?

Has anyone else heard of using epsom salt with gallon of water for magnesium and sulfur issues? I'm told you can water them or spray them during lights out. I've had some issues before with magnesium due to soil pH recommended by maker didn't follow it I later corrected it pH
