getting ready to flush tomorrow.

Looking great at your spot, curious on why the flush looking this good. A little defoliation is all I would do. Well done my friend

Thanks, we’ve been across some bumpy spots but came through so far. I was actually using this as a lead in to the question as to when, where and why to do a 10 week flush (or whatever week flush really). I was going on the fact that I havent done a complete flush. although at 5 weeks I did a thorough plain water flush, but the inside of my buckets are coated with salts and I have one big girl that refuses to go into bloom and I thought that might help to spur her into bloom. What are your thoughts on this?

I use GH FloraKleen to help remove the salts during grow if needed to clean system. Plain water is good but if you need to remove the salt buildup you could try something like FloraKleen. If
You are using Hydroguard from the beginning it will help breakdown salts during your grow and all but eliminate the buildup and provide a healthier root system. Also some Humic acid added during will also help.
Sometimes Autos down get the key gene that allows them to flower with a long light period. I’ve had to cut lights down to 12x12 to induce flowering for my ‘Auto’ that wouldn’t flower with long light period.

Good advice from @LateNightGardner. They look to be between week 2-3 of flower??

ah ha! I will try that. the thing is the two plants in front are both GDP. the one on the left is under scrog is the only difference. its the same for all 6. the ones on left are all scrogged. Theres GDP in front with BLD in the middle then SSK in the rear. I think my pump might be a little weak because the sets of plants get smaller the further they get from the reservoir unless its just coincidence that the strains I chose were in order of plant expected height. Anyhow I think I caused the delayed bloom on GDP2. I couldnt make up my mind as to how high I was going to lolipop her and wound up taking 2 more nodes off just as she was going into flower, and it seems to have parked her right were she was getting ready to flower. GDP1 is flowering and has been for a few days now. So I’m just trying to make the best of a bad situation I likely caused.

Yup, SSK in the back has been in flower for 7 days. they were all started at the same time so I expect they will be somewhat in time with one another. and yes definately FloraKleen. Hydrogaurd is a bio product yes?

No worry about 12x12 on autos that are flower in 18x6. They can also flower in 12x12. I actually held off on the failed auto until my other 3 autos were in the final week of flower I did trim the failed auto to keep here canopy under my lights until I flipped her. She did stretch so keep that in mind if you choose to flipped her later. Just treat her like a photo.
They look like they are doing good and are gonna make some nice nugs.

Yup I’ma gonna put em on 12x12 toot sweet(I know I misspelled it) and yeah shes my biggest girl in the room already, and shes too thick to do much of anything with. guess I’ll move my fan and lights accordingly.
Hydroguard is a bacterial root inoculant that is designed to decompose organic matter and break down nutrients, making them readily available for the plant. It also helps roots uptake nutrients more easily as needed.
Hydroguard is a bacterial root inoculant that contains Bacillus amyloliquefaciens. This bacterium is known for its ability to enhance the symbiotic relationship between the roots and their surrounding medium, suppress and resist damping off diseases in soil and hydroponic gardens.

I might try that next grow. I went sterile this time just to have less to keep track of.

That’ll work but you’ll need to continue to use H2O2 to keep them sterile. Also you’ll need to keep your water chilled to below 70F to keep the bad microbes away. 68F is your target water temp. Also keeping your water well oxygenated keep the bad stuff away. O2 will keep the bad anaerobic microbes in check.
To prevent bad microbes from colonizing your DWC cannabis grow, you can take the following steps.
- Avoid using rockwool as it can promote pathogen growth.
- Autoclave airstones to eliminate pathogens that may be present in their porous structure.
- Use beneficial bacteria such as Hydroguard to outcompete the pathogens that cause root rot.
- Keep an eye on pH levels and adjust as needed to promote the growth of beneficial microorganisms.
Anaerobic microbes are microorganisms that can survive and grow in an environment without oxygen. In a DWC system, anaerobic microbes can be harmful to the plants as they can cause root rot and other diseases.
To prevent the growth of anaerobic microbes in your DWC cannabis grow, it is important to maintain a high level of dissolved oxygen in the nutrient solution.
Dissolved oxygen is the first line of defense against anaerobic bacteria that cause root rot. You can achieve this by using an air pump to aerate the nutrient solution and provide oxygen to the roots.

I’m gonna check my local hydro store this evening for some H2O2 stronger than 12%, but yup I hyper oxygenate everything. and my chiller is set to 67.

Now you should not go too strong or you’ll shock you plants and kill them. It is important to note that H2O2 is a powerful oxidation agent and may destroy all organic matter including beneficial bacteria, which is why it is used to keep the hydro res. clean. It is also recommended to use H2O2 in hydroponic mediums along with synthetic nutrients only.
If you’re using 12% use 2ml. per gallon of water. Note that h2o2 generally will break down in 24 hours so you’ll need to repeat every week at least to keep any bad microbes in check. Also it will kill any organic matter in your medium so you should use inly synthetic nutrients. Or go to something like Hydroguard to colonize your root zone and skip the h2o2 all together.

I’ve had good luck with the H2O2 so far.

H2O2 is good tool for the right option. Most big commercial grows also use beneficial microbes to eliminate bad microbes and break down salts inthe system. H2O2 has little effect on salt buildup. I just subscribe to that perspective.
These plants are six weeks from germination and beginning week 2 of flower.
Only h2o2 I’ve used is initial cleaning of buckets and tent.

Great looking bunch of ladies, nice full canopy. Grats

do you use LST or top/fim 'ing or both to get an even canopy like that?

Thanks @zmon. Yes, I did top them all but I’ve found that they grow so fast they really don’t need much to produce an abundance of colas. Once they stretch I start taking the minor growth from the bottom. And do some more pruning as they flower.
I have taken two cuttings from two biggest of three plants on the right and one each from the three on the left on November 30th. Just basically top them all.
The all started on October 24, seedlings planted in a cloner under florescent.
Then went to 3 gallon buckets on November 3.
The three biggest got promoted to 5 gallon buckets on November 20.

I accidently topped one of my autos and figured that was the end of it, but has split off into two mains that dont look any smaller than its sister which didnt get topped. So I’m thinking I’ll scrog one row and top the other for comparison. I do like the scrog so far.
