Plants are starving if you haven't started feeding at the proper ph and ec. There is no nutrients in coco. Cheers

Yellow on Cotyledon normal?
Is that yellow on the cotyledon leaf normal? 2 days post sprouting and that one had helmut head the first day. I was able to remove seed pod by lightly lifting the edge of it with tweezers.

Light green tops
I've got one plant with extra light green tops. Any suggestions or is this normal sometimes? See my diary for feeding details. I've treated all plants exactly the same the only difference would be the type of pot (airpot) and I didn't root prune like I did the others.

Should I be removing sick leaves?
When running into issues with yellowing and necrosis, is it better to leave the affected fan leaves of to take them off? Worried removing so many might have hurt me more than leaving them and trying to just fix the issue.

Blotched spots on fan leaves - calcium or fungus?
Started noticing some funny spots showing up on the big fan leaves. Light colours patches in non-uniform shapes-looks like it's spreading across a few of the big fan leaves only. Not sure if it's calcium deficiency or a fungal infection. No insects noted.

Nutrient burn, magnesium def, light burn? Leaf tip yellowing but not turning brown/curling
4 week since planted autoflower, both started getting this at the same time. First time running autos, grown in FF Happy Frog soil. Soil was used for 3 weeks in a different grow so nutrients may be needed. Light burn, mag deficiency? Have only used ph 6.2-6.5 water, no nutrients.

'rips' on leaves
Leaf damage between the veins only found it on two older leaves, had problems with calcium and magnesium deficiency early on, could this be a symptom of that or what else could it be? Haven't found any pests..
