Burning with Nutes or Lights or????.....

How is 4000 watts overkill? My room is approximately 630 cubic feet or 90 square feet, which is about 45 watts per square foot...........

I agree its not over kill.. I think its nitrogen deficiency.. Usually that fading starts when you cut out nitrogen towards the end of the grow. Add some more nitrogen to the effected plants nutrient soup. Other than your yellowing the plants look healthy. Your PH swing is fine I would always set at 5.5 in DWC and then let it float up to 6.3 to absorb all the nutes it needs..

That yellowing is root system stress/issue/rot, also the pots are too small for those nice thick bushes. If roots are brown its a pathogen control issue(my guess),get some H202.If roots are white then i would flood the pots more often as the plants are suffering from lack of moisture as well.
Correct it or they produce very little in weight.

The force is strong with BUDS

The roots arent pearly white but I do not believe its an issue with rot (I've been there). The roots are somewhat tan but not brown and you may be correct about the 2.5 gallon pots. Ill send more pics of my roots and of the room in general when my lights are back on. Im watering 4 times a day for 15 minutes. Should I water more?

Also, Im flushing today (just b/c I do not know what my issue is) and Im curious to a target PPM when I pick back up tomorrow with nutes.

ok i would like to see the roots. Also i recently grew autos in soil in small pots and they went like yours, not good produced fuck all. Did the next batch in larger pots(not massive pots about 2 sizes up) and they were 100% better,greener, thicker,healthier and drinking and feeding better which allowed me to water the plants more often.

Ok. I have more pictures. The roots are tan but not brown and slimy like I have experienced before. Some of my plants do not have hanging roots and some do. If you look at the overview photo, you'll notice that the one plant stands out with the size and color of the leaves. Also, the picture named nuteburn?, what is this? Im confused. This looks like nute burn. Could my problem be that I had nute burn which in turn led to nute lockout which is why I am experiencing other issues.....Please help. I am currently running H20 only.

WOW! You should be using net pots and not those type! Your plants are starving because they don't have the root structure to support the size of plants you have!

Just a wild guess, but per chance are the plants that are doing better have more root structure coming out the bottom of the pot?

still i wish i had 4 1000hps x) hope u solve the problem br0 and try taking out a light maybe it will help ..

Hey, when was the last time you calibrated your PH and EC meters? I had a problem due to faulty readings on my meter.

Im not sure how to correct the problem but one of my plants are dying and the other (only Corleone) are yellowing like crazy and seem to be dying as well and Im only 38 Days into Flower, with at least 20-25 Days remaining. I've flushed for 3 days and started back at 1.6 EC (200 Liters of R/O water,) Here is what went in my reservoir: Bud Candy 140 ml----Sensi CalMg 180ml---Sensizym 140ml---Kushie Kush 140ml---Connoisseur A 280ml---Connoisseur B 280ml. My PH is 5.7. I raised my lights and I dont seem to see any good results. Let me ask this......just to let you guys know, I am legal with this but I am growing 10 Plants (4 Cataract Kush, 6 Corleone Kush, per my patient). I have 5-1000 watt lights going (just added one during flowering) and I have CO2 coming in pretty efficient. Should I be feeding stronger? Advanced is tough. Does anyone have a good formula for AN? For my setup. This is the second time that I have struggled during flowering. My veg is GREAT. But my flowering SUCKS!!!
PLEASE HELP!!

You were right BUDS! I had ROOT BOUND in 5 of my plants. I have never experienced this before so I did not have a clue as to what it was. The 2.5 gallon pots couldnt hold the roots comfortably and therefore they eventually start sucking the life out of their leaves and all the water that it could find. I just purchased 3.5 gallon pot with nettted pots as inserts. Im gonna transplant my vegging girls into these net pots and drop them in these nice BIG BUCKETS and now my roots will hang out of the net pots into the bucket. Oh well, I guess you live and learn.

Thanks!

Also, how could I have corrected this ROOT BOUND? Water more?

Im gonna go ahead and say right off the bat, its more than likely the nutrients. We have very high powered lighting and there has never been a problem with our light burning the bud. The nutrients somtimes overpower and cause the plant to die.
