Plant Toxicities (I think)

[GreenLegacyFineCannabis]

Pics are of a room that's vegging into screens to flower in a vertical bulb room.
Temps are perfect, watering is right I have a meter to test the soil dampness. The PH of my water in this room is 5.7 the soil when dry is 7 but 6.3 when wet...which I'm also curious about. It's barely getting nutrients the one nutrient being used in this room is botanicare grow and some basic cal- mag. The soil is Fox Farm Ocean forest and Light Warrior mixed. Which is a really good mix. I've flushed with pure PHd water and am lightly watering now. Not sure what else to do?

too small of pots for plants that big, root bound.

I have had my moms in 5 gallon pots for months and they are over 6 feet tall. I really doubt that is the issue. Almost looks like your using water softened water but with the lights I can not clearly see the issue.

those look like 5 gallon? some plants do OK some don't like small pots, the leaves are curling down something with the roots is my guess.

Actually those look like 2 gallon pots..Hard to tell, But Backtracker seems to be closer to the issue than me.

They are all in 5 gallons in that room
Thanks for feedback guys. That's what I thought root bound but all my buddies are telling me I don't know what I'm talking about lol

 

[GreenLegacyFineCannabis]

And I know it's hard to tell but those plants are 4 feet tall and bushy it's Obama Kush indica

 

[MrClone]

Very slight chance it could be root rot to.. Doubt it but just in case they are not root bound may want to check that.

Here are some pictures with the light off...

Mildew? Too much water?

Those ridges on the newer leaves mean something as well as that powdery looking stuff.

What's the Humidity?

 

[GreenLegacyFineCannabis]

Powdery mildew isn't going to cause the plants to do this. And as I said I have a moisture meter the plants have a huge root ball. I'm spraying the plants which is probably half the reason they look like that. I sprayed them heavy with neem. They looked a lot worse and are kind of snapping out of it but I'm still kinda confused.

It's below 50% in the room always had powdery problems in that room

You can eliminate the PM with higher brix. .use an amino acid with like superthrive and spray neem oil religously.. You can spray them every day with just neem/water with no issues up until 2nd week flowering

Could trying to veg my plants out through the screens with an HPS be effecting them?

I notice I have this problem everytime it goes from (MH light) in the veg room to starting to get bigger in the screens in the flower room for a couple weeks

Sometimes plants shock a little with the light transition because of the different spectrum of light. I will usually add supplemental lighting meaning I keep the MH and add the HPS so I do not get that stretch and they seem to not shock as much or not at all ... and it is a little easier for a transition.. I also have tried to use a MH for the first two weeks in flowering.. But it seems that If I go lower wattage on the HPS while keeping he MH full strength at 1k watts. Dialing down the HPS to 600 watt for days then go to 750 for 3 days then to full power

Thanks brotha you have been very helpful so has everyone else I'm getting her dialed in. Getting powder gone has always been an issue at my place

I use, silica, Amino acids, kelp, fulvic acide and superthrive in my feed. It should raise your brix making them more resistant to the mold and even pests. I also use neem oil, superthrive with kelp extract, silica, and fulvic acid as a 5:2 ratio as a foliar once a week ( example if i use 2 tablespoons kelp I use 2 and 1/2 times fulvic acid as kelp) this works much better than adding one or the other by itself.HIgher brix also means better taste and stronger smell to.

 

[MrClone]

Actually doing a brix text now on plant that went from 14.2 to 14.9 and see how much it raised since last week

Looks like N toxicity and heat at the least. I think you might be potentially overwatering, too. Pretty severely.
