Any idea what these bright spots can mean? Plant is 2 1/2 weeks old and those spots show only on older growth.

Looks more like a pH issue. Was the coco washed and buffered? Many brands claim to already be....how well they did so is often debatable.

Excess calcium ?
Hi, the young top leaves are starting to have a yellow tip, I guess this is a potassium deficiency due to an excess of calcium in my watering water that is hard and I add extra calgreen and the fact that I water with fertilizer 2/3. Could you confirm the problem ?

Do I have an (Mg) issue?
Leaves turn light, have black spots and 1 leaf rolls in upwards. It got Epsomite with every watering so I guess it's not a deficiency. Last time there was not even a drain. So maybe nutrient absorption is blocked? Should I flush? Is it to stressfull for this autoflower?

Nutrient or water temps? Water temps between 15⁰C and 20⁰C but usually closer to 15⁰C.
Not sure if it's a nutrient deficiency/excess or water temps. Please refer to pics. 2/3 plants are showing light green and yellow tips. New growth seems light in colour as well. pH - 5.9 to 6.1 Daytime temp - 75⁰ to 79⁰ Night temp - 67⁰ to 70⁰ Coco with Gaia Green 444 and 284

Spots in Leaves
Today I noticed these spots in one of my plants. It doesn’t seem to be any of the usual symptoms (as far as I could check), or at least it’s not clear for me... aside from having these spots in a few leaves, the plant looks healthy... do you guys think I should be worried ?

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?

Given the pH is 7-7.5, and given the fact that the tops are fading and thinning while the lower parts of the plant remain green, would you also agree that this is early stage iron deficiency?

What's up with plant 4
Quick Question, Plant 4 in all of my pictures, it's showing signs of a nitrogen deficiency but it's not possible the last run off I tested was 2250 with a pH of 6.0 what else could be causing the leaves to look like they have a deficiency. Burnt tips I understand.

I added a new photo from today - the Blue Dream only, again after one day of watering, looks like it's asking for something more - just can't tell. I have put a lot of N, I can't believe that is what it needs.

Losing colors :'(
I watered only 2L of water without nutrients this week (pot 30 L) You can see it on the diary photos, the plans have lost their colors (yellow). I wanted to know what exactly it was due to, because I read on the net a lack of nitrogen but I would like the expert opinion Thanks !

Light stress? Nutrient burn?
Iam not sure if this is light stress or nutrient burn. Iam leaning more towards light stress. I have incresed the distance of my lights, which will hopefully clear up the problems. Iam watering with a ph of 6.5-6.8. Iam still fighting with fungus gnats which is fun.

White/Yellow snipes on leaves? (13th day of growth from seed)
I noticed a huge change in my plant leaves in less than 24 hours. The leaves look like they are getting burned out. What is happening? I'm uploading pictures to see the problem and also the growth conditions. I'm watering once every 1 or 2 days (PH = 6.0). Not using nutrients yet

I need advice on what to do with this plant. I flushed her a bit and I think nutrient burining is not showing on new growth, what ppm should i feed her?
I watered only last week and mesaured runoff ppm and ph. Water was 350 ppm and 6 ph and runooff was 700ppm and 6.7 ph. Before when i fed her with 850 ppm runoff was 1500 ppm. I would continue to water only but there was a lot of yellow and pale leaves so gave her light dosage.

Growing 2 plants under exactly same conditions: one is completely healthy; the other one got some leaf issues. The discolouration starts in her older leaves and then spreads onto the younger ones. Been giving them stimulators with the following: Ca, Mg, Fe, Mn, Zn, Cu, B, Mo
