Chlorine at normal levels wont hurt plants. They need a bit as a micronutrient.Appently if your going to use tap water you should draw it out and then leave it out few hours? Something about allow some of the clorine to evaporate... Not 100%
I do use tap water, I might try to use a carbon filter next time. Temps are around 12 - 15 ºC (57ºF). Thank You!what kind of water are you watering with? my leaves look like that when i cheap out and use tap water. looked around, and it might be from the chlorine. Also, it could be a little heat stress. what are the temps where you live?
I give it 20 hours of light 50% of it is natural, but when its dark outside i give it some cfl lights, not a really profesional system as I am just experimenting. just watered today, last time was 3 days ago.Haven't read the whole thread, but I have read up a lot on the plants "internal water pressure system" that helps it lift its leaves up towards the light.
The plant exerts energy during the daylight hours to strengthen its cell walls, which causes the leaves to lift up towards the sun. There are a lot of things that can affect it (light, nutrients, water, temperature, salt build up, etc) but at that early stage, its probably one of 2 things: light or over watering. Two of the leaves are picked up nicely, but it kind of looks like the plant has juuuust a little bit of stretch to it.
Are you giving it light by putting it in the window? How much light is it getting per day? Its not a big deal, its mostly holding itself up.
Damn chemist shows up when we're discussing kemestry.Just want to note that while Cl is definitely an essential element for plants, they take up chlorine in the form of chloride which is elemental ionic Cl-.
In terms of water treatment\disinfection the chlorination comes in the form of hypochlorous acid (HOCl) and the hypochlorite anion (ClO-), which are referred to in this context as "free" or "available chlorine". You get hypochlorous acid by dissolving chlorine gas (Cl2) in water. Chloramines are formed by mixing hypochlorous or "free chlorine" and ammonia. Chloride, chlorine gas, hypochlorite and chloramines are all chemically distinct compounds that feature the element chlorine. Chlorine gas, hypochlorous/hypochlorite and chloramines are more related chemically, and they are all oxidizers which can penetrate the cell walls of micro-organisms and interfere with cellular materials (such as amino acids).
