This looks like it could be ph lockout . Try flushing your plant and see how she does

Hi! Check on "tobacco mosaic virus". The yellowish stains could be signs of it. Good luck!! :)

Kind of looks like very weird Potassium excess. Could be a form of PH lockout.

First grow yellowing seedlings :( nute problem?
I seem to be following all the instructions on grow temperature range, light distance, and watering schedule(only watering hen the medium is drying); I've hardly used any nutes until day 22 as advised and I personally think this has caused me some issues although I may be wrong.

Strange coloured fan leaves (3) on one of my 4 plants, maybe some sort of deficiency? Thanks people!
Hey there smart people! I have about 3 strange coloured fan leaves on one of my 4 plants and I’m not really sure what to make of it. To me it doesn’t look like any deficiencies that I came across per say. All other leaves look nice and healthy. Kinda randomly scattered. THX!

Yellow spots on leaves
Are the yellowing spots signs of Leaf Septoria? I'm assuming it's more of a nutrients issue but have never experienced LS and wanted to get some second opinions.
