First grow - my setup

Hey bro, I only have two weeks more experience than you so take my advice with a grain of salt. This is what has worked for me so far.

I have had salt build-up on my drip rings, hydroton, and grow tent floor pretty much since I started adding nutes. I could scrub everything every couple days and it would still reappear. I have stopped worrying about it, and so far no issues. I'm just going to sterilize everything after each grow. It's the nutes that's cause salt build-up. I figure if the nutes are loaded with salt, a slight build up can't be too bad.

To answer your question, from my research, yes you can flush out your system with straight RO water. Probably let it run through your system for 12 hours. Hopefully someone with more experience chimes in.

 

Update: first pic is the Thai lights. The rest are the GB. Been flowering just under a month.

 

Thanks magic! I have recently started mixing my nutes differently. I ph water in a 5 gallon water jug, let it recirculate/bubble for a few hours ( I use an extra recirculating tube from the waterfarms which pulls water from the bottom of the jug and spits it out in short bubbly bursts up top). I than mix in micro, let it recirculate for a bit, than mix in bloom and let it recirculate for 12-24 hours. This method enables me to keep my ph/ppm more stable.

 

Thanks man! I'm loving dwc and rdwc so far!

 

Hey guys!
Back to work so I'm away from home for two weeks! I took a month off that's why I was able to post so frequently! They were fine when I left a few days ago! Hopefully they are alright when I get back. Only time will tell. I will let you guys know on in a few days, I'm going to jet home for a few hours.

 

Thanks for checking on me! My plants should be ready to harvest in about two weeks! I'm going to go home in a few days to switch out my nutes for straight water!

 

Quick update:
White widow is looking good. Left for a week and came back to a pretty healthy looking plant. These two little guys had their waterfarms pretty much drained in a week!

Thai lights and GB are starting to fill out nicely. A few leaves have turned brown on one of the god buds?

 

Thanks guys! As you've probably noticed I changed my setup's and plans!
I downgraded to 2 individual waterfarms in the 3x3 veg tent. And I also downgraded my 1000w to a 600w in the 5x5 flower tent. I plan on only having 2 plants in flower and 2 plants in veg max! I'm going to be using scottyballs waterfarm scrog method. I don't know why but I got slightly paranoid! I want to use less energy and have under 6 plants (I'm in canada)

 

Thanks for the reassurance! I'm still going to keep it under 6 though, to be a bit safer. Any ideas why my leaves are turning dark brown magic? Or anyone? I'm not too concerned to be honest, just nice to know!

Also the ppm had risen in the week I was gone about 150ppm. Ph was acceptable in both systems, about 5.8. I did a 50% res change and dropped the ppm down to 700. I'm going to give them another week or two of nutes before I start my flush. I figure an "8 week" strain would be better left for 9-10 weeks before harvest. They are currently on day 45 of flower.

Another predictament is I have a sativa and indica in the ecogrower! I honestly didn't think of this until now! I'm thinking the Thai Lights will take an extra two weeks on top of the god bud. What I'm thinking I'm going to do run very week nutes (300ppm) up until a couple days before I harvest the God Bud. Than I will switch to straight water and continue flushing the Thai Lights for the two weeks. It may nit be perfect, but I will make it work! I've learned lots this first grow.

Also I added tinsfoil over the two waterfarms in the veg tent to keep splashing off the lower leaves and light off the hydroton.

 

Thanks for the help magic!! Unfortunately there is no way to Seperate the two strains. 2 of the god bud are on their own res so I switched them to straight water today!
