She’s due for the chop in 14 days max I just cleaned out the Rez and reset it too 930ppmI didn’t even know Plants could survive at 4000+ PPMs. If your TDS meter is accurate, I’d change out the solution ASAP and get the PPM’s down below 1400.
I top, lollipop & SCROG the sh!t out of my plants to direct all the plants energy into maximizing colas. I’m guessing you’ve got at least 4 weeks left to go, so those buds should swell up nicely if the high PPMs don’t kill them 1st.
Double stuffed sorbet by dna geneticsWhat’s the strain? And that plant is so thick & bushy, it’s blocking light to the lower colas & buds which substantially diminishes bud growth.
1x 600 watt hpsNice! Should be tasty.
How much light are you using?
I trim anything below the canopy and anything that’s not getting good lighting.

Ok... so you want to keep your reservoir between 65-73 F. Use a chiller or heat mat to maintain temp. Best to get some Hydrogaurd or the equivalent to keep roots healthy. 1200 ppm is on the high side - I personally don't go much over 900 ppm.
What nutes are you going to be running?
I
20 is probably OK, 25 is going to be pushing it unless you either run beneficial microbes or a sterile system.
I ran my RDWC system for 3 seasons with rez temps always around 25degC by using hydroguard or GFF to outcompete pythium.
Since it seems that you're in the UK, the availability of these may make running a sterile system easier.
I've done about 50 DWC grows in RubberMaid tubs since '01 and going to get back into again. Been playing in the dirt the last while and it's a major PITA with crappy results. Just not a dirt farmer but can kill it with DWC.
Used mainly AN 3-part from the beginning and with RO water can go the whole grow without changing nutes once with great results. I may do a change after the stretch then switch to Lucas formula style feeding. Just Big Bud and Rhino Skin for AN additives. Any old CalMag will do and of course some Epsom salts. With the pH perfect nutes I never, ever bother checking pH. Just ppm and then add nutes in small amounts to raise or maintain my target ppm.
Start clones around 300 ppm then go up gradually to no more than 1000 tho that can be too high if your RH is low. 500 can be too high here in the winter with grow room RH around 20% a lot of the time. The plants go thru way more water and take up more nutes than they should which leads to toxic salts buildup that really starts to show around mid-flower.
I always ran sterile tubs using food grade H2O2 but 10 years ago or so built a chiller out of a water cooler and fountain pump so could keep the nute temps down to 65F easy. Stopped the peroxide and never got root rot.
I've had 3"/day growth in later veg. Never seen that in soil or soilless.
Good luck!
Just bumping the thread, any input on how I can improve are appreciated!Between & 1/2 lb to a pound per plant, depending on how long I veg them, keeping them healthy, pH management & fresh water...
My tents are only 3 x 4, so I can only do so much with that space.
