    Trying to grow 4 CBD plants in one DWC

    Upped the EC to 1.0 and it seems to be making an improvement. I think the issue was caused by a combination of low EC and stress from topping. Does anyone know if high CBD low THC varieties generally need more nutes?

    Trying to grow 4 CBD plants in one DWC

    Yeh you're probably right. 4/4 seeds popped so I wanted to see if I could finish veg a little earlier by starting with more seedlings. Thanks for the help. I'll go back to just A+B and CalMag for next water change and go from there.

    Trying to grow 4 CBD plants in one DWC

    Hey guys :) Maybe I'm being a little ambitious but for my latest project I'm trying to grow 4 plants in one 70L DWC. 2 of them are Humboldt Blue Dream CBD (the ones on the right) and the other two are Dr. Seedsman 30:1 CBD (the sick looking ones on the left). In the following pics you can see...

    Brown roots/root rot? After adding great white.

    Also just some comments on your setup: I have a feeling that using a towel to block the light like you have isn't the best idea. I would be paranoid that it is fucking with the micro humidity around the leaves etc as towels are very absorbent. One way to get your humidity up is to hang a towel...

    Brown roots/root rot? After adding great white.

    Yep 1.4 - 1.6 EC is way way way to high, bring it down to like .6. When u notice the drop to .4 bring it up to .7 or .8 etc. Its likely that your roots are dyed from too much of just the A + B. Ideally you want your EC to remain stable and the plants to drink lots of water (they wont yet be...

    Brown roots/root rot? After adding great white.

    You should be fine in that case, make sure to keep your EC pretty low, around 0.6 at that stage of growth increasing to about 1.0 or 1.2 towards the end of veg. Those rust spots on the bottom leaves are something I get using H&G too but I'm pretty sure its because I get greedy and jack up the EC...

    Brown roots/root rot? After adding great white.

    Hey mate, that is likely not root rot. I've had exactly the same looking roots as you when using House and Garden nutrients. It's the additives "roots accelerator" and "amino [something]" that are dying the roots brown. You'll know which ones I'm talking about because they're black as the night...

    Bluelab ph controller

    Hey mate, I'm in the process of doing the exact same thing! I've set up automation for my humidifier and exhaust fan and am just about to purchase the components for a ph controller. I think im going to grab the Atlas scientific EZO ph circuit & Voltage isolator, use my existing blue lab probe...

    2 seedlings in each rockwool cube, keep or chop?

    new pics: So its kinda interesting actually: the leaves on the two smaller plants of each strain have rusted up and died (likely due to the 24 - 48 hours I was giving them 1.0EC, why do I always get greedy with nutes lol ) but the leaves on the two bigger plants seem to have tolerated the...

    2 seedlings in each rockwool cube, keep or chop?

    New pics: So maybe someone smarter than me knows why the leaves of my early plants are dying like the leaves on the little mutant pure indica on the left. My last 3 grows I've had the same issue... leaves look really healthy then all of a sudden start to rust. See this thread for previous...

    2 seedlings in each rockwool cube, keep or chop?

    Maybe a little late to do that as the roots have been developing for a couple of weeks now. Would have been a good idea had I thought of it earlier though. What i did notice though is that in my last grow was that the paper surrounding the rockwool cubes didnt rip, eventually constricting the...

    2 seedlings in each rockwool cube, keep or chop?

    Thanks guys :) I'm of two minds - part of me wants to just rip the weaker one but the other part of me is thinking that it just means that I wont have to top the plants and will save a couple days in veging time. How come?

    2 seedlings in each rockwool cube, keep or chop?

    Hey guys :) After a couple failed goes at popping single seeds I ended up soaking rockwool cubes and chucking 2 seeds in each cube to double my chances. Well it turns out that 4 seedlings sprouted, 2 in each cube. I was planning on doing 2 plants in 1 res (2 pots) but now I was wondering if...

    Best Water Temps? + Do It Yourself Water Chiller Details!

    You should only need one pump. Its best practice to use an external pump where possible to reduce heat in the res and leave more room for the roots to grow without disruption.

    Purifying my poorly made RSO (Pics inside)

    So i used a syringe to collect the brown layer. It completely took away the alcohol taste. There is still a little burnt taste, but a decent bit less. There is also a lot of chlorophyll taste but at least now its tolerable. Looks kinda gross though and I dont know how potent it will be. I...

    Purifying my poorly made RSO (Pics inside)

    Hey mate thanks for the info :) I'll definitely put a bit more prep into it next time. I was too keen and just kind of went for it... Any ideas on how I could purify the stuff I have now though? I was thinking of freezing it (to make it easier to remove from the container) then mixing it with...

    Purifying my poorly made RSO (Pics inside)

    Hey guys, I made some RSO from all of my AVB (approx 2 - 3 ounces), trim (approx 1 ounce) and about 1 ounce of flower. I chopped it up into reasonably small pieces and poured isopropyl alcohol over it, stirred it for about 5 mins, then drained it. I did two washes with iso. I then put the iso...
