Brown spot
On only one of my plants there is a brown spot which I have no idea where it can come from. I didn't give too much fertilizer and I regulate my ph between 6 and 6.5. Some idea?

Should I start fertilizing or monitor the pH?
Hi, I'm a beginner, about 10 days after switch, my lower and slightly higher leaves started showing signs of damage. I grow them in a greenhouse in strong sunlight, but I think that they don't get burned, I haven't fertilized them even once. What do you think of this?

Maui Waui CA deficiency?
Can anyone confirm or guess at the kind of deficiency my plant is having? I am not sure if "hard water" (instead of RO so far) is the right answer or if I need some special sauce... Thank you! Details here: https://growdiaries.com/diaries/139533-grow-journal-by-fejg87fb2skvf

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!

What’s appening to the little northern light auto?
so far I have only given her the rqs growtablets plus a break of plain water and given this reaction today I have also started to give her some advanced nutrients (MGB) is it just a delayed nutrient problem or should I worry?

Are those nutrient defficiencies? Which ones?
A plant had interveinal chlorosis on new leaves and then proceeded to show brown patches between veins on middle leaves. Another has coppery brown spots on leaf edges on the middle of the plant. Both were rootbound in living soil (peat/perlite/hummus + ammendments).

brown spots on older leaves
The brown spots are appearing more prominently on the older leaves. Overall, the color of the leaves is rather light green compared to other grow diaries. What could I do to fix the deficiency?

Thankfully not my plant but what do you think this deficiency is? My first thought was actually that one plant fungus r something that causes brown circle like spots. This is the top of the plant. No curling to leaves.
