i use UC roots in my DWC , solves the root rot issue.,, am guessing by the photo your root rot issue is water temp being to high ,since its outside and aeration cause i see no airlines going to your buckets , both those cause root rot. are your trying this the Kratky method ?

when running the Ghost Line you want your heavy feeds(ppm) on weeks 5 to 8/9 , then you want to start lowering your ppm going into flush,,good luck

am also running the Ghost train Haze 1 by Rare Dankness but in coco in 3 Gallon pots under a 600hps, using Advance Neuts.. and i wouldnt run my ppm that high even in coco let alone dwc. i run my base(micro/grow/bloom) around 2.5/3ml/l with my Additives(bud candy/b52/overdrive/rhino skin at 1ml/l and thats putting on the high end of what i feed in coco during heavy flowering at about 1200/1400ppm atm on day 63 of 12/12, starting wk 10 tomorrow ill only use overdrive & water but ill up it to 4ml/l (700ppm)for this wk , next wk flush ,,,,

Are there any tips out there for increasing yield in the final 2 weeks of flowering ---- yes thats what the overdrive is for,,, ALSO use "Dense" by green planet neutrients it has a NPK of 0 0 62,, this shit hardens up you nugs therefor increasing the weight/yield... in a dwc setup i use 1gram a liter in the last 2 weeks but 1 day per week only , you use this alone with water only for 24/36 hrs then empty your rez and refill with your reg neuts, for the rest of week.,,, this shit will give you up to 1600ppm of pure potassium per 2gram a liter,, under a 250 light i would use maybe .5 of a gram per liter and go from there,

@ The8thChevron if, " theres no actually benefit to flushing " then why do it ? ,,the reason you flush is to let your cannabis plants “use up” any extra nutrients contained in the plant and buds. This way there is a much lower level of nutrients left over after harvest, and it's those extra nutrients that can change the smell, taste or (most often) “smoothness” of your buds in a negative way,, and a 2wk flush(most times it 1) is done in earth/promix/coco ,not dwc , dwc is 3/4days

use this as a ppm guide -- Seedlings: 100-ppm First Half of Vegging Cycle: 300-ppm Second Half of Vegging: 450-ppm First Half of Flowering: 750-ppm Second Half of Flowering: 1000-ppm End of Flower, As close to 0 as possible use half these values for rdwc , when starting new strains , and then raise it or lower as need be (ppm goes down more food , ppm goes up less food.) , so for a rdwc 250w hps drop these values by 2/3 and slowly raise or lower as you need , remember less is more in dwc

you running you ppm throught the roof,, 2200 is just way to high in a rdwc with a 250w light thats why you have neut problems, And you need to lower your base neuts when adding addatives & , you could be having root issues also, am running bubba island kush DWC @ 650ppm on the 500 scale in flower under a 600w light , also this is a 10/12 wk flowering strain (not a 10/12 start to finish autoflower) you using overdrive in wk 6/7 of flower ,you should be using it in wks 9/10 or 10/11 and your bigbud you should start using in wk 2 of flower till wk 8/9 or 9/10. your plants still have 3/5 (1 on the left 5/7) wks to go, i would have like to see the root zone . are you using a root inocculant ? i use UC roots, and i use UC roots&water to flush for the last 3 days. .. also when doing rdwc dont start plants at different times,cause you feeding the overdrive to the left plant thats 2 wks younger then the right(thats is getting overD 2/3wks early)..and dont run multipul strains in the same rdwc as not all plants have the same feeding needs,, and if you really wanna know when your plants are ready wait till the tricomes are 100% cloudy & starting to turn amber... hope these tips help , cheers .
