Nesta’s Blueberry Cherries and Ice Cream Cake RDWC

[Nesta]

Gmo sould be able to handle 500 ppm, personally I woul lean P deficiency

interesting. I’ve been following the ratios for GH. I can step up the P though. I didnt know tip burn was a result of low P.

 

[SSgrower]

I use Canna Coco a&B with Rooted Leaf by agritech,Rosin Bloom or FF Big Bloom as I switch out the two. I get burnt tips but not a problem I see any breeder speak about? Can you elaborate? SS

Deficiency or Nute burn

This is from my last grow Started to see what i thought was a calcium def around week 1 of flower. Heres a picture at day 14 of flower feeding at 340 ppm 700 scale or 250 tds on the 500 scale. Tips showing what i thought was cal def because they haven't bean above 380 ppm and 180 of that is...

Thanks Smoke!

This Ice Cream Cake is going beast mode!

 

[Nesta]

The ice cream cake continues to explode, but I’m having issues with the blueberry cherries. I don’t know if this is genetic issue or environmental. Running RDWC so I don’t think it’s a root zone issue, as everything else looks fine. Feeding at 500 ppm/5.8ph and 1.2 VPD.

Any idea what could be going on?

This one here looks like a Magnesium deficiency, to me, but I can't really comment on the funky growth. What's the humidity like in that bush?

 

[Nesta]

Humidity hovers around 60% depending on temp.

 

[GrumpAzz]

Do you just have the one B&C or is it two of each in the tent? If two, are they both acting the same, or just the one?

 

[GrumpAzz]

Where to you keep the pH?

 

[Nesta]

5.8

Just one B&C. 2 ICC and 1 GMO. The B&C is the only one doing this

 

[Aqua Man]

Whats your temperature and how are you calculating VPD?

Do you have fans directly on them?

 

[Nesta]

Temps 73 (lights off) 80 (lights on). I am calculating VPD using AC Infinity controller. I am using air temp and not leaf temp.

I have 4 oscillating fans in there, but none pointed directly on the plants.

Whats the lights on humidity? Still about 60?

 

[Aqua Man]

Whats the water temps also

 

[Aqua Man]

Also pic of the roots. This is kinda looking root or bug related. Light seems a bit high for them also.

You said the other plants are all fine. Do you have pics of them?

Lights off humidity is around 54. Water temps 73. PPFD at the canopy is 480. Yes everything else looks pretty good. I’ll get a shot of the roots shortly.
Here is the full tent. The back right is a funky GMO cut, so I’m not concerned about that one. left side are both ice cream cake and the front right is the B&C in question

How the stem at the base of the plant look?

 

[Costanza]

I think your VPD is too high at 1.2
I would lower it down to 1 and get your humidity up in the high 60s low 70s with lights on
I don't hit 1.2 vpd until around week 6 of flower

Here are the roots and stem.

Interesting. I guess I’ve run too high VPD this whole time. Thats an easy adjustment.

 

[Nesta]

I just realized I never posted. What’s in my nutrient solution.

GH Trio ( 40% of the light feed schedule)
Hygrozyme
Southern AG GFF
Armor Si
Ruby Fulvic
Cali Magic

I could be wrong about the VPD causing this, I'm no expert grower I just saw that high VPD and thought maybe that could be a cause who knows

 

[Aqua Man]

Do you have an IR temp gun to check temps?

Just the way the leaf curl is at the base of the stem and spiked leaf edges reminds me of russet mites. Also the yellowing on new growth which can happen in early stretch but usually combined its a root or pest issue.

Ill have to look more at this later.

What light cycle are you on at the moment? If 18/6 480 ppfd is pretty dam high for those plant sizes

 

[Nesta]

Im on 18/6. I knew you were going to tell me to turn the light down . Im at roughly 32 DLI. What do you recommend at this stage?

what week of flower are you at? looks to be around weeks 2-3 I don't think 32 is too crazy

He is about 30 DLI and its not crazy but its getting to the upper limits if everything is dialled in and the plants are happy.

Genetics, environment and all other factors play a huge role. Some can easily handle that and some cannot. Plant size plays a huge role also and sativa’s can naturally handle more light than indicas. It has to do with total leaf surface area and sativas are lower.

personally im not a numbers guy. IMO we should go by the plant response and use numbers as a ballpark to get us close.

IMO the goal in veg is to grow the least stressed and health plants we can so that wr can hammer them in flower

Im in veg. Will flip in a couple weeks.

 

[Aqua Man]

If you drop down to 400 and see how that goes…give 4-5 days to see how they respond. It is also possible its more than light related and the plant is stressed and thus is not able to handle the light the others are.

Process of elimination takes a bit of time but also provides valuable knowledge and that’s worth more than a perfect grow any day of the week
