This is a magnesium deficiency my friend it starts off as a yellowing of the leaves between the veins. It then slowly starts to climb up the leaves and while it's climbing, some of the first affected leaves will develop rusty-looking spots. But don't get confused. The rusty-looking spots are actually a sign of calcium deficiency. When a plant is deficient in magnesium, it will also become deficient in calcium.

I have lots of yellowing on the lower leaves of one plant. After reaserching I think it’s a nitrogen deficiency. Also today I’ve noticed lots of teeny tiny white/clear bugs! I’m super anxious about it, thinking my plants are goners. Any idea on what they are?Week 10

I have been having trouble with my leaf tips and edges appearing yellow and then turning brown. At first it was just the bottom leaves that were affected but now more of the top leaves have the burnt appearance just not as extreme as the lower leaves. What can I do to fix this?Week 6

Yesterday i see new yellow leaves (plant 2). I have just checked them again and on the second plant the two small leaves are now brownish. What could that be? I water every two days and the soil is not wet but slightly moist. The other plant 1 grows wonderfully.Week 1

Hey guys, I have noticed that some of the upper leaves are turning yellow. I read that it may be because of heat stress or light burn but I'm not entirely sure and just wanted to ask what i can do to stop other leaves from having this issue. Anyways, what do you guys think?Week 15

Hi all!
I was checking on my plants and noticed one of them is showing yellow/brown spots in some the top leaves, only showing on 1 plant but I’m nervous it’s leaf septoria?? The plant is in week 10 and is my last pic on week 10 diary. Does anyone know what this could be? :)Week 10

The leafs started to look yellow in the middle when I checked on them today. They looked fine to me yesterday so I guess this happened in the past 24-48 hours, not sure why. It can be seen on Day 12 pictures. Is this normal or I should be worried?Week 2

My leaves on plant getting yellow at week 4. Gave her a flush for a few days with a pH of 6.0 but the run off stayed at 4.8. continued flushing with a high pH of 8.0 then the run off went down to 5.8. I did add peat moss to my Coco/perlite. Could that cause the pH to be low?Week 5

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?Week 5

Super soil growers ever come across any deficiencies? See a couple lower fan leaves I removed today. I'm sure leaf loss to some extent is natural, but I read that the lower leaves are your indicators, so I wanted to run these by yall to see if you suspect and deficienciesWeek 8

Seed started off fine. Germinate well, half inch tap root, placed in 3 gal. pot. 12 hours after she broke surface and that was it. At day 2 no new growth. Noticed the two leaves have brown on the tips. Temps are 75-80, humidity is at 60% and only use 6ph water. Help....Week 1

Saw a lot of yellowing in the flowers, not sure if its enough or too much nutrients, or not enough water or its a pest. I was suggested neem oil to get rid of the pest creating those white spots, any other suggestions about how to get her to look healthier and growing faster?Week 6
