white vain on the leaves

ok i have an auto white widow thats 17 days old from seed and has been overwatterd i think but it also has white vains on leafs and am wondering what caused it?
info:
im growing outdoor but am giving few hours of light before and after i put her outside under floresent light.
my soil is homemade compost, perlite and fish blood and bone.
temps range from 28-20ºc, (the later when i leave out on warm nights).
im not sure what humidity is.
i water with water from my private water supply which has a ph of 6.9.
thats all i can think off ill try post pics soon and id really apreiciate any input.

here is pic soz about quality

she perfectly fine, good job to for up in the high lands lol

im not to far from you, just down a bit lol and ive struggle this year outside, the extreme changes in the weather wow, like today low 80 s up to early afternoon then tropical thunderstorms followed by now a massive drop in temps and massive rise in rh, all in 2 hours and its been the same now for 2 weeks, so that what i meant by good job, i was not been funny, i just read my post back and thought or no,

lol do you know we just had tropical type storms like mostly all last week which is why i started taking her inside. lol and thanks for comment i really apreciate it.

the only thing sadj are the tips of you're leafs starting to hock or bend slightly or is it just the pic, if so slight over fert or the start of or soils to hot ive never used what you listed, as i use coco, but ww are tough old girls and are quite tolerant to high ecs, or the start of calcium can give bent tips, so just bare it mind thats all, youre water, do you know it starting ec, as it sounds very soft lol ph 6.9, so im just thinking watch out for the cal/mag deff, use egg shells crushed n boiled, you can Google it, dolomite lime there is a few

lol thanks again for advice. i think you might be right about soil being to hot im pretty sure i put to much of the fish stuff in tho it is slow release. im fairly new to this and am not sure what soft or hard water is. thanks again

lol again what is ec is it electric current?

hard water will have more elements/minerals in it, like calcium and magnesium chlorine ect giving it a higher ppm or ec reading, were softer water has less crap in it and less bad pathogens ect it also contains less minerals ect and will have a lower ec readings, and if that tip bending gets no worts it will grow out, the new growth does not look dis-formed u should be ok, just keep an eye on it, but have a read to on adding some cal/mag,

ive got to shoot. lights out at 12, ibe back on 2morrow, so i send you a friend request and if i can help in any way im always more than willing to help a fellow grower, if i can lol

lol my water might be soft. cee it comes from miles up hill and goes straight from river to house so i always thaught it there would be an abundance of minerals in it lol probly should stop being such a tight ass and invest in some proper equipment. i have plain lime and epsome salts will they do if its a cal/mag def? also is spring water good for plants cause i got a natural spring next to my house lol thanks for all the help.

Looks good to me. I don't think it's really having any real issues other than being a bit too wet, and that can cause the discoloration you're seeing too from not being able to eat and displacing all the oxygen from the soil.

I'm talking about the light green, not the white. The "white" is normal. I'd more worried about the lightish new growth that isn't evenly light and the bit of light coloration on the older growth, but don't treat it. Definitely don't treat it foliar right now, just stop watering it so much.

Epsom salt i think it's a tsp per gallon or tbsp forgot, foliar feed and it'll fix it if it's the issue. Dolomite lime in the soil will help but don't foliar the lime. Spring water is probably abundant in minerals and microminerals. Are the plants around the spring healthy? If so, it's good water

i also used rock dust to add minerals to soil and it had cal and mg but it is super slow release and i kind of skimped.

I'd say if anything it's avoiding the rock dust because it doesn't need it yet.

lol thanks for advice ye my flor lights arnt very good but its only whilst weather is crap lol im ordering 6 105 actual watt cfl bulbs because ill probly be bringing them in cause weather is being a bit to unpredictable. and yeh the plants round the the spring grow in abundance and are very vibrent considering the clay soil. thanks again lol im knackerd going to go to bed lol thanks.

I think its fine

thanks spartacus420
