A lot of times lower light is lower temp. So many camnabis university programes have found out that hi temps in late flower lower tricome and resin production for yield increases. Some Indica pnenos were knocked down 7% total thc above 80 degrees. The use of CO 2 did not change the outcome...

I agree number 1 mistake is not having a water test done and not recognizing the variable ec readings from cold and hot taps. The descaler water was charging my salt and binding calcium. The clue was the salt in the bottom of the bucket when I changed it out. I had both lowered ppm and ph by...

O sorry no I know how the leaves died. oldest fan leaves with largest spread got sick first. I thought it was specs of PM but it would brush off and then a black eruption would start. It spread as a rusty looking blight like high ph beans will get. so far no growth less than a 3 inch leaf...

Ok I see the issue. You are in soil I am hydro. The static ph idea in hydro requires a monitoring ph system or hourly adjustments. It is recommended in hydro to roll your ph from 5.5 to 6.5 as some nute uptakes are PH related. The key is tayloring the time it stays in this ph range based on what...

After I decided it was a pathogen I defoliated and took out to the garbage as to not spread the spores. I am dragging the tent and plant outside and running a sulpher smoker and then a wipedown. I agree that I had nute problems but after going to ro the plants look better but still got...

which mAsterblend product do you use? is it used with a salt carrier like jacks? I have the ppm on all nutes for what I mix and would like to compare what bag or bottle you use.

I am confused. Jacks 321 Which Jack’s fertilizer(s) should I use to feed my cannabis plants? If you are using a pure water source (reverse osmosis, distilled water, or rainwater) we recommend the 3-2-1 program or the 12-4-16 program. If you are using any other water source (well water...

Update Treating for a rust pathogen. What I thought was Powdery Mildew was the spores spreading. Sulpher burner on the way. Defoliate was harsh and I rewiped whole tent with ACV at 10-1. Plant looks bad. still only fan leaves inpacted but not many of them left. Can a pot plant live with no...

After some more research I am going with a rust disease. I no longer think it was PM as it was never dust like always a dot of white that I could brush off. Will cull any leaf showing signs and have a sulpher burner on the way. Hope this fixes it.

The problem started at 76.2 f and 70% RH. I had noticed some white spots on tent walls and tiny white spots on leaves both fan and new growth. I needed to get RH down to 60% and on VPD chart that means around 72-73. Various university programs on cannabis state 70-85 during veg with no problems...

update My problem is that the pictures look like cal def, mag def, qnd a fungal issue. Starts with small brown spots on fan leaves and progress to major damage and leaf necrosis in about 3 days. Running out of fan leaves. I do not cull until leaves shrivel. Non fan leaves are not getting this...

update Ph adjustment down from 6.3. Ppm on new mix 700 ppm. Due to PMildew max RH adjusted to 60% which to stay in vpd range temps at 72. Pm treatment included apple cider vinager on all surfaces and my wife lovingly wiped all fan leaves with neem. After 24 hours at new temps plant doing well...

Ok outside the box thinking. It sounds like you can not damage THIS door. New interior door is $49 and it is your door. Hold the other one until done and reinstall. Prehungs are $69 and its 3 pins and bam.

New game I installed recently. It pretends you are a pot grower and have to make endless changes on a screen chasing the mythical VDP.

update Powdery Mildew has made an appearance this morning. Just a few spores on tent walls and a couple of white specs on leaves. The mildew is only on old fan leaves that were stressed earlier not new growth. I have tiered RH from 80% in seedling to 58% now 4 weeks into veg. Plant still...

update Message off to Jacks about water testing and if this descaller can be causing problems. I did a massive dofoliate on all the badley damaged fan leaves. It left me with this. Cut out only damaged fan leaves. Looks like a spindley gg4 auto with problems. My wife made an observation...

Weed in the early 80's in Ohio was low power seeded bags of ditch weed. 35 an ounce. 110 a QP. Just about the time I quit ( aircraft mechanic subject to drug screens ) we started to see " sensimilea" which was pure buds and sold by the gram. Smelled like pine and was very potent for its time.
