DONT THROW THEM AWAY!
Wait a second. You have fem'd autos so your talking about plants that will rival the usual idea of a "weed." They dont look too horrible, but you need to take some time to think about what you can provide them.
What have you been giving them so far as far as the following
2. Fresh air and wind
5. PH levels of feed and in soil.
6. How often do you water. How much?
What your seeing looks like a nitrogen deficiency it can be caused by either not enough nitrogen in your feed and soil or there is a PH imbalance causing your plant to not be able to absorb it. This cause slowed growth because Nitrogen goes hand in hand with photosynthesis which also involves chlorophyl. When there is a lack of nitrogen chlorophyl breaks down in the leaves allowing another form of plant color to shine through, which is yellow.
This always happens to flowering plants, late in flowering, as they plant will have stopped absorbing as much Nitrogen when flowering started and takes every last bit it can to give to its flowers so it takes it from the bottom of the plant that isnt as important and gives it to the top. In Nitrogen def'd plants the old growth slowly goes yellow while new growth looks okay but not perfect.
Once a nitro def happens the leaves may not fully recover if they recover much at all, however new growth will be okay given that you solve the issue.
Either not enough N in the N-P-K on your fertilizer or your PH is off.
Your gonna want to test the PH issue first because if you start feeding more and its a PH problem then you'll go from one extreme to the other and burn em with too much food. Trust me they dont just get fat like we do. Unfortunately.
However as far as putting outside, alot of people think that if they cant seem to provide well enough in an indoor grow that, mother nature will adopt them and nurse em into outdoor monsters. This is not how it works. The outdoors is the best area to grow, it has just the right conditions providing the strain you grow is close enough to the hardiness zone it likes. It will grow anywhere tho so for the most part your good.
What you have to understand is the plants will go through extreme shock if you just kick em out one day and dont come back for a while. They arent used to the outdoors so if you do decided to get em outside do so a little bit at a time, maybe stick em in a sunny window for a few days, then let em outside for a few days during the morning before it starts to get too hot and bright outside. Then eventually let em outside all day. Then eventually let em outside all day and all night. Then they will be hardened. This may actually give em enough oomph to make em go at the ground like some kinda of taz devil and quickly obese themselves but with less chance of overfertilization.
So it boils down to this. Figure out why they arent getting the right amount of N and decide if you can provide what they need inside now. If you cant start getting em ready to go out on their own. These plant withstood the test of time, and now its withstands the test of well, us, but it will eventually die if conditions do no go back to normal.
