Just seeing those things fill out.

Maybe next time you can just grow 1 humongous plant.

Can I run something by you guys?

of course

Hey @Wisher619 why is it I have to drain and refill my system every week or two?

the reason why you have to dump and refill
is because.......
through the course of the week your plant may be taking down some elements more than others
if you just keep topping up
what will happen is those elements that are accumulating will get high enough that it will block other nutrients from uptake

those elements will cause an imbalance
so every 2 weeks or so you dump and start fresh so you know that you are giving the correct ratio of elements

Would it be worth taking the 400W LED (cob 3590x8) out of the 4x4 and putting in 3x3, or no?

I have 1x 250w LED (200w Cob 3070 3500k, 50w red/blue). 2x23w 3500k CFL and 2x36w 6500k LED for a total of 368w.

I'm leaning towards no. But it crossed my mind.

But 118 of those watts are not high bin, so not as effective/efficient.

Is it possible to tell which nutes have been uptaken given ppm and ph changes?

no that is why you gotta change it out
in big agg production hydro
they will get a leaf sampled every week
which will tell them what they need to up and down
there are also new electronic meters that read the analysis of the stock solution to tell what needs to be upped usually those systems use a doser and typically each element is in a seperate tank

the 400 would kill in the 3x3 but it would fare better for you where it is at

Excellent thank you!

 

[mandalaman]

Ok so my 400w tent is looking unhappy. Not sure. I'm going to try and get sips done tomorrow but not sure so need a quicker backup plan if you think there's some major issue.

@Wisher619

 

[mandalaman]

Is it possibly too cold?

 

[mandalaman]

Better pics.

 

[m8ty]

Yes the cold will make 'em yellow like that ..

Part of me is thinkin to get a 630w for the 4x4. Veg RDWC in the 250W and Flower RDWC in the 400W. The other keep things as is and add a 315cmh to the 3x3 for flower. Wondering if the extra cost will pay off almost immediately...
