Hi Everyone,
I'm having a few issues with my first indoor grow, a lot I've been able to resolve myself, but this one issue I can't seem to figure out and hoping for some guidance.
This new plant is 17 days old, and started showing symptoms on first set of leaves about a week ago, from there it has spread to the 2nd set, 3rd set is looking ok for now, but the issue comes on fast, the 2nd set looked as healthy as the new growth 2 days ago.(only transplanted into 5 gal pot today).
For watering, it was initial watering of medium then basically nothing for 12 days, have recently watered a little bit last few days before transplant today, it may of gotten a little dry on a hot day and night before watered the next day.
I've also had it appear on one other plant (last pic), whilst I have 8 or so others that are not showing any symptoms, I've defoliated a lot of it from the older plant
Medium is well balanced but soil was cheapo big box store, water is PH'd and aerated, temps have been high at 27-29c the last week, with humidity ranging 50-65%, but try to keep temps around 25-26c.
My first thought was calcium/magnesium issues, as I tested my tap water and it's only 50ppm, but only the two plants showing issues, haven't really fertilised a tonne, trace amounts of fish emulsion and seaweed tonic mostly, but have added tiny amounts of Epsom salt and gypsum to water to see if that would help, issue still progressing though.
I'm not experienced enough on nute burn but it doesn't look like it to me.
Now trying to think of other potential issues, the seeds are very old (10 years) and storage wasn't the best, but I did soak them in 3% hydrogen peroxide for 12 hours before they went into paper towel/ziplock, so hoping that cleared anything that might of been pre-germination related.
Could vapour from a humidifier cause the yellowing and spotting, I don't treat the water that goes in and we do have chlorine and chloramine treated city water.
or could it be bacterial or fungal related?
I can answer any questions about it as I've probably left off important info.
Thanks for any assistance
