Yes, it is in the open air and outside the house. It is white on the leaf of edible milk.

Also check for bugs and powdery mildew are those outdoors?

[Bluey]

Yes. But give a reduced amount....you should fix your pH issues first though

Yes, I use city water. There is tap water for drinking in our country. I pour water in a bottle for a day so that the chlorine settles. I bought calcium fertilizer, do you think I should give it?

A quick fix given you are using compost is to add some dolomite lime to your water...I don't know the quantity you need though. This will add calcium and also up the pH and do both immediately

[Bluey]

So you are giving it tap water? Can you measure the pH waste water runoff that first comes out the bottom of the pots?

A combination of leaf soil, coco, compost, sheep manure

[Bluey]

You have a calcium deficiency.

Treatment will vary depending if your growing in coco or soil.

First step is to check your pH. pH too low at the roots is the main cause of what you are seeing

it is my experience that if you light up the seedlings with florescent light in the 6400 kelvin color temp range, the younglings love it over here.

[ChubbNugg]

Yes, by god, Every last one of them!

Deep violets low low 400's nm will promote root growth in early veg. some say.

Some say that the same and lower UVA/B/C will boost oils/cannabinoids and terps in late flower but this has failed to be replicated in all controlled lab testing to date so could just be bullshit. A dark period for 3 days prior to harvest probably works better IMHO.

I used 405nm in early to mid veg and have always filled a 13 gal pot with roots during veg. Is it better? No idea. I think with or without it would fill anyway so I've shelved those globes for purpose built grow lights but continue to supplement from flip with 660 & 730nm to close to harvest...they are not very strong and mounted 30 to 36" above canopy so just leave them on a 12/12 with the main lights. Works well I reckon.

I don't know does it? What have you read about seedling an light?
