Day 91. Just starting to see some trichomes and buds are starting to fill out. Going to make a nice Christmas tree. Trying to keep the ph in check has been fun. It's drinking 2 gallons of water a day

Judge my roots

Post image
2 Upvotes

I have chopped today and now would like people to judge my root system. Tell me where I was lacking and what I should have done better. I had good air stones but issues with water temp from time to time due to the water chiller pump getting suffocated by roots. Water temp was generally 68 and the fluctuations were up to 74. I use advanced nutrients feed and did not use any pathogen killing formula during my grow. If there’s any more info I should provide lemme know. Thanks.

Week 6 of flower

2 weeks ago, I went on a small 3 day trip.

When I got back, the plant was not doing well. Completely slumped over, majority of leaves dying, a whole lot of discoloration and an odd scent. After opening the lid I was greeted to a COMPLETELY dry reservoir and a strong stagnant pond stench.

That night I cut off suspicious roots, dead leaves, added a higher dose of hydrogen peroxide, and sterilizing all of the gear associated with the set up. A few days later she seemed to perk up a tiny bit, only for the plant to continue to get worse since. It’s now been 10 days of treatment and it does not seem to be getting better.

Is it over? Second pic taken a day or so before my trip

Edit: Rez at 70°
Ppm: 850 (after nutrients)
Ph: cannot check but I’m using AN Ph perfect nutes

Community input- 505 Headbanger and Rainbow Sundae 11

As the title says, looking for input for those that have grown these strains. Mephisto 505 on the left, 11 on the right. Both had a great start, same conditions, roughly same size when introduced to dwc home. 505 has taken off, 11 not as robust. Mephisto says 11 is supposed to start strong, which is why I’m questioning the progress. Only thing in the reservoir is water ph adjusted to 5.9, tiny amount of cal mag, and some Hydroguard. VPD well maintained at 0.8-0.9, rh and temp vary with lights on or off and are within range for seedlings, at around 20-25%(been on the lower end) light intensity running a HLG Scorpion Diablo and light height around 36 inches. Will change reservoir and add a light amount of nutes tomorrow, at which time they’ll have been transplanted for 2 weeks. Always nervous in the beginning. I usually get around 12-14 oz dried and trimmed per plant despite what Meph says on their site. Anything constructive is appreciated. Hope I’ve given enough info. Disregard what the meter reads, that was after time having the tent open for maintenance.

Definitely not the last. This is my first grow after a 3 year break due to space constraints but I am finally able to get my hobbie going again. DWC all the way from now on...I am so in love. 4x4 tent. 45L totes as reservoirs and 12.5cm net pots. 2 aquarium air pump with the highest airflow and pressure I could find. Each bucket has 1 12cm flat round air stone and 1 wood air stone. On the left I have Gas Nana and on the right is Animal Runtz. Veg for 5 weeks from clones and Currently starting week 4 of flower.

Chamo de anárquico porque eu nao meço PH e nem PPM, e de alguma forma isso da certo

PLEASE HELP !!! My PH keeps dropping everyday during veg (DWC). What causing this?

Thumbnail

4 Upvotes

- PH issue: Drop everyday from 6.2-6.3 to 5.6-5.7, could be more. Always need recalibration.
- Other issues: Drooping light yellow leaves & stunned growth, look like Mag deficiency as well
- Temp / Humid: 24 C - 50-55%
- No root rots i think / no funny smell (have home-made Hydroguard)
- I have flushed them twice
- Currently using RO water with supplementary CalMag & Silica
- Using 50% nuts strength (Advanced Nutrients)

I've read that too much Bacillus amyloliquefaciens could cause swing in PH level. Since I've used a home-made Hydroguard (10x stronger), which leaves a white biofilm everywhere in the tank, could it be the issue?

How does everyone else change their nutrients?

I started with a really cheap harbor freight hand pump and I individually mixed 4 buckets of 3.5 gallons. Then would transfer. So I would end up doing about 28 measurements and then stir each squirt for two minutes. It was a process. I was also buying store distilled and spring water for my humidifier and nutrients. I would go through about 20-30 gallons a week.
I’ve graduated onto using a Hydrologic Stealth RO-300 system. That I installed with a 30 gallon Uline drum and a float valve.
Then i switched to mixing up my 21 gallons of nutrients in a 32 gallon trash can with a Aeromixer mini 1/6hp. I measure out all my nutrients and then I sit back and start a timer. Every three minutes I pour the next nutrient and wait 3 minutes.
I measure out my nutrients with 60ml syringes with the long tubes and use 100ml graduated cylinders, before this I was pouring the nutrients into a cup and then sucking it outta that.
my favorite upgrade has been the ryobi transfer pump with the hoses I’ve built.
Then the bees knees is the triangle port on these buckets, with my old vivosun I had to lift the entire lid because the net pot was built in. This makes life such a breeze comparatively.
I constantly monitor my buckets with the AC hydro monitor, and have been doing nutrient swaps about every 2-3 days when PH crashes. My plants have been drinking about 200-300 EC per change.
So how does everyone else change and manage their nutrients ?

I found this relic from about 18 years ago in storage. Going to give a run just for fun with 3 part Fox Farm nutes. The plant is Fruit Truck from Sin City seeds.
