Re: please help first grow problems ..

First thing I can see is over watering. Then onto some serious nitrogen deficiency. Also you have nute burn. Overall diagnosis is nute lockout.
You should flush with 3 parts water to 1 part pot size. So for your 5gal bucket, you need to flush with 15 gallons of water and let them dry out, and really dry. Some even wait until the top of the soil is crispy dry. Then I wouldn't use nutes for a few days after that and then gauge it yourself on how much nutes. may be g a good idea to use 1/4 nutes as recommended on the bottle at first and raise as you the plant grows more. It may be a good idea to re-check your ph and much of these problems will go away on their own once your PH is correct. Perhaps lower a little to 6.3.
They are not doomed yet, she looks as if she's a tough one. Just keep an eye on her.
