However their first two leaves after a while got what looks like burns on them, but I took it as "nutrients/energy is going towards the new leaves, so maybe this is normal

==>> great observation.. perhaps .. i dont know abut the SINGULAR conclusion ...

it seems.. the insult.. is long gone.. as it is not on the new growth ... i wonder about cold damage ... OR ... improper hardening off if you started the seed indoors ...

its hard to tell if or how off color they are ... and whether it is a camera trick in the covering .... or true color.. is this your concern ????

i also wonder... though you are pnw.. could it have gotten too hot in there ...

ken

EDIT: also.. if indoor start.. did you use peat pots ... WAG!!! ..

and why not sow a few more seeds .. a later crop is better than no crop .. eh???

Thanks, just in case i will take some pictures today in the daylight so coloring will be much better.
They werent actually started indoors, they were planted directly as seeds into the raised bed. As for too cold, i dont *think* so, we never got frost or temps that low, and my cloche has been on (never take it off yet). As for too hot? Well we had SOME days of 80F and blaring sun (hotter in the cloche but i kept the soil well watered).

Btw on the corner the Bush Beans are on, i make a hole using the corners of the Cloche, so theres an air vent.
Yes i have another crop growing thats about a week and a half past germination.

Here are the new pictures in the day-light:

http://sdrv.ms/12C14cO (Notice the very top leaf is wilting...im not sure if thats normal because as you see below theres new growth so maybe the energy and nutrients are going to that or if something is wrong)

http://sdrv.ms/10Y5BYF (With this one its obvious the top leaves is discolored)

http://sdrv.ms/1aghwlS (This one you see the top leaf is wilting as well, again i dont know if thats normal or somethings wrong)

No one has seen that before on leaves? Or what?

ken made several comments.

The problem is environmental stress.

The 2nd link you just posted very clearly shows the dead tissue between the veins, most clearly so on the leaf that's toward the back a bit and nearly dead center. Dry tissue between the veins like that indicates the plants ran short of water, probably suddenly and briefly, also probably on your 80 degree day.

When it comes to beans, temps below 50F are too cold. (The same goes for tomatoes.) They require consistent warmth.

The wilted topmost leaves (1st & 3rd new image) are due to stress -- roots aren't keeping up with the tops' demands/requirements for water. Reasons why include dry planting mix; and/or small root system; and/or cool to cold soil temps; and/or high air temps -- singly or in any combo you can think of.

Thanks Jean.

My watering habits are once every other day at about 5-7 pm when theres still a bit of day-light left. Sometimes once a day. The temps have always been 50+ since i planted the seeds (straight into the bed, which is covered with a cloche).
What should i have done on those few days of 80F to have prevented them from running short on water? Watered every night?

I dont know about small root system, they were planted spaced out like the seed-directions said directly into my raised bed.
Its just weird because literally nothing else i am growing is having a single issue, yet these bean bushes have two issues.

Im not TOO worried though because they are continuing to show new growth of leaves and the like.

What type of planting media are you using? It doesn't look like soil. It might be too sharply draining to hold the moisture consistently. The cloche, is it fabric?

Its a 50/50 mix of great soil from my local Nursery and Fertilizer/Compost soil...im not sure exactly what it would be called, i will try to find out.
I dont *think* thats the problem just because i have (after a few days of not watering certain areas that have nothing growing) and dig with my finger down a few inches of soil and its moist.
(If you go to my website: http://nathansgardens.weebly.com/ you can see many pictures of my raised bed/cloche)

No its not fabric, its Green-House plastic material. Im like 90% sure this is what i bought and used: http://www.greenhousemegastore.com/product/4-year-greenhouse-film/plastic-greenhouse-film

I have one corner folded open in such a way that it creates a vent, i will most likely buy two zippers and attach them to the cloche so i can zip open vents.

You're cooking your plants under that plastic. It's not meant to be so close to plants. It's for greenhouse walls. Remove the plastic.

That makes 100% sense, but i have seen others have pretty much exactly what i have setup, so is there a way to have it on and it be better?
I mean like...have it further away from the bed and taller so there is way more air room, and also have the zipper vents i mentioned earlier and keep them fully open?
I know theres other types of Cloches i could use to protect against bugs/animals and they have a tiny bit of thermal retention, like Summer-weight (which i own a roll of) but like i said they only have a tiny bit of thermal retention.

Btw i have been kinda thinking that (cooking) is a possibility and especially with today's and this coming weeks weather (full sun, 70-80F) i took it off earlier today.
