White stains on leaves

Hi all,

I'm doing my first grow and my initial attempt using rockwool failed, so I switched to soil and so far is growing fine, but some of the leaves have white stains on it. I already checked for spidermites and it doesn't seem to be the problem.

I would appreciate if the experts could give me some advice. Pics attached

I'm doing Indoor and the plant has 2 weeks. I started watering the plant when the two real leaves showed up with 1/4 nuts, then 2 week 1/2 nuts. I give them water when I see they need it and they're on 18/6 light schedule a couple of in away from the plants with a room temperature around 25 C (77 F).

I also have no idea if the plant is too big or small for this stage.

Thanks

hows your humidity? it looks like it could be nutrients dried up on the leaf. but if its way too humid it may be powdery mildew starting.

all that is, is dryed up moisture wipe them down and make sure your Humidity is at nothing higher then 55% or your going to get moisture buildup like that

I notice these 'stains'; are all over the pots. Your plants are nice and they excite you but could you stop ejaculating on the them.

...and quit using nutes, you don't need them yet, your plant looks good sized for 2 weeks. Start using nutes when you transplant into a bigger container.

Let me guess, your spraying them with water from the sink, or some other source where the water is not purified and thus leaving calcium or mineral stains. Get some distilled or purified water that wont leave mineral deposits and spray your plant down with some very light rubbing of the leaves it should come off. Its not good to leave it on there, it will clog the pores in the leaves which absorb stuff like air, i think. Just my guess.

don't worry about it. the plant is fine, but be careful with nutes on young plants. GL

Thanks guys for the help.

I will keep an eye on the humidity, but I guess it should be around 40-45%

I spray them with water ph around 6.5 (no nuts) from a 5L Bottle that I bought on a shop, and not using water from the sink, then I give them some water (also from the same bottle) on the soil with nuts
