Yellowing leaves (help needed)

I am growing belladonna and they have been growing for roughly two weeks in a little homemade grow box under CFL's. I have started to notice on one of the plants that the bigger leaves are starting to go yellow at the tip. I think this could be due to overwatering (as i water them everyday) but i am unsure and am looking for other peoples advice and oppinion.

are you feeding them anything other than water?
is there anything in the soil time released fert?
do you PH your water?

Whoa, that's not good at all, it 'looks' very Nitrogen deficient, more details needed please. What soil, how long in it, what type of water are you using? ie tap water, distilled, well water, rain water etc.

Greenair, the more info you give the better the answer will be.

i use tap water but i let it sit for a couple of days before i use it, im using fox farm soil and its been growing for about 3 weeks now. i was using fox farm grow big for veg. hope that is sufficient info babygro.

Hiya Ventricle

Please don't let your water sit for a couple of days, that's probably the worst thing you can do to it - use it within an hour of drawing it from the tap otherwise all the dissolved oxygen will vaporise out of it into the air - the roots need this dissolved oxygen.

Don't worry about ph at this stage either.

I strongly recommend you repot your plant into a fresh set of soil and nutrients and I rather suspect that will cure your problem. Don't feed it anything except plain water, for the first 2-3 weeks, except perhaps a drop of superthrive per gallon of water, if you have some Superthrive or perhaps 0.5-1.0mil Seaweed extract per litre if you have any of that at repotting time - both of these help to releive the stress of repotting.

Looks like you started ferting too early. You should have waited a few weeks before feeding ferts.

I would flush well with plain water...wait a until soil gets a bit dry before watering again. Then....try adding a bit of ferts....1/4 strength.....next feeding water.......followed by ferts....maybe 1/2 strength if they can take it. But start by flushing the salts that are likely there out of the soil.

From what you guys have been talking about i think my problem is pretty much the same. I have been using tap water, and leaving the water in my spray bottle.

I'm not convinced that my local water's chlorine level is high enough to damage plants.

But I still run a bubble bucket with only tap water. Just in case. The chlorine should be dissolved by the time I use it.

And keeping the water moving instead of sitting for a day or two can't hurt either.

I am using water from my dehumidifier. then shake to oxygenate it at each use. probly overkill. the city water here is harder than my head. rofl...still am having high ph numbers, IF I can trust this cheap ass meter, its reading about 7.0ish. Ideas to lower it?

PH+ and PH- i think. Which you can buy from a grow shop. If the PH needs lowering you stick a bit of PH- liquid in it. Others will know more than me though.
