Stem/Leaf Question

Its moving into my 13th day of the Apollo11 and Cali-Haze vegetative grow using a 150watt Hps. Things are looking lush and green...except on a 1 or 2 of the leaves the ends are starting to get crisp and discolored. The color is hardly noticeable...what is causing the crispness? Also for some reason the two plant's stems are bending in towards the light without any help as if they were competing. Ive just been rotating the plants to make sure they don't grow to much in one direction. Should I get another light? Temps are running in the low 80s.
 
How close are the plants to the light and have you started feeding nutes yet? Any way you can throw up some pics?
 
the plants response to the light is just called phototropism - its normal and a good thing.

the crispness on the end of the leaves however: are you just using tap water? cos if you dont leave it for at least 24 hours, the chlorine burns the tips of the leaves..
 
Ive just been using tap water lately with nutes. I was thinking of starting to use filtered water from one of those water dispensers down the way. Would that water be any different?
 
Yes, very different. Also, tap water needs to be allowed to rest for 24 hours to allow chloramines (by-products of chlorination) to evaporate. If you are not doing this harmful salts can form, like potassium chloride. These salts create electrical imbalances when you water and wind up further locking out elements like Magnesium.

A good filter for you, if you can afford it, would be a Hydrologic small boy with a carbon fiber filter. This will remove 99.99% of these chloramines, and is much more affordable than a RO filtration system or paying by the gallon.

Depends on how many plants you are growing. The more plants you grow, the more water you'll need. Might just be easier and more affordable to pick up a few 5 gallon jugs and filling them up at the RO water machine in front of your local grocery store.

Also a 150w system should be more like 10" from the plants. They don't have very good casting distance, but also make heat pretty easy to manage, so you should be able to keep it a little closer. Use the back of your hand to determine where the "bubble of heat" from the bulb stops, and keep the top of the plants just outside of that heat.

I have come to the conclusion to use filtered water down the street from a dispenser in front of a convenient store. Im a little confused on filtered water, if it has chlorine or not. The only place to get RO water around here is hours away. Also If I were to get RO water wouldnt I have to use Calmag?? The plants seem healthy but tend to be to turning yellowish around the edges of some of the leaves. The nute configuration I have been using is 5ml a+b, 5ml canazyme, and 4ml Riz.
