Help! First grow...so close to being done!

[stareyez]

Hi,
So these are in their 4th week of flowering. Recently they started to yellow heavily on older leaves and curl up and turn brown on the leaves that are yellow. The leaves are "crunchy" to the touch.
About my girls
:1) On 12/12 lights. One 1000 HID, 7 plants
2) Growing indoor
3) Watering schedule: Every 3 days, Bloom, HPK and Extreme Serene all from Organic Roots.
4) Growing Medium: Organic mix from grow store...don't remember..
5) What stage of growth: 4th week of flower

PH has tested normal. Ventilation set up with circulating fan and duct hooked up to blower fan.
Unfortunately they suffered a large amount of stress due to moving, heat and other problems but this is new.
I have read many threads and am thinking nute burn or Phosphorus deficiency based on other pics. Please help...I'm so close to the end!

They look burnt. How much are you watering and how often do you feed?

When your in flower the plant will use up it's stored Nitrogen, and this is normal, which will cause the leaves to yellow. Your's look like they have too much water and a nute burn... so I guess I'll wait for your answer form my question above.....

I water them until a little water runs out the bottom. The containers are 3 gallon, made out of "breathable" materials so the water just soaks through. I feed them every three days. Thinking of flushing. My "teacher" has never used these nutes, has the same clones and they are doing fine. Thinking maybe too much build up...

You shouldn't feed each time you water. You should water water feed. Stick your finger it's full length into your soil and dig around next time your going to water. If the soil is moist wait a day. Your watering a single plant in a 3 gallon bag til it comes out the bottem, it sounds like you just answered your own question.... I use a half gallon watering can and put less than half of it on each mother plant in 2 gallon pots every other or some times every third day. The plants in flower are in 3 gallon trays 3-4 plants per tray and get one can for each tray every 2 days. let your soil dry out and cut back on your feeding

What about water feed water feed

 

[stareyez]

I always stick my finger in the soil to make sure it is dry. Because of what my pots are made out of they dry out pretty quick. My watering can is 1 liter, which I use 1 1/2 for each 3 gallon bucket.
I will switch from feeding every day. Thanks everyone for the fast response and advice!
