Dutch Passion Dutch Passion AutoXtreme in 30 litre airpot

1= soil ph is 4.5
2&3= soil ph is 4.3
4,5&6= soil ph 3.9

I think it means your soil ph is lower than you thought it was going to be.

Now you need to look at the chart someone already posted to see what nutrients its taking and which ones are locked out. Basically, none.
 
Hi Bob :)

Hi Dude thanks for doing the sums.
Sorry to be a right dumb ass but can you please explain how you get those numbers?
Ive seen the equation above from Blue but mate maths and me just dont mix, ive really no clue.

So with the numbers you have done, Whats the plan now?
What do I have to do?
Do I need to feed higher ph water?

helpppppppppppppppppppp :)
Hey dude if only someone mentioned checking the run off a few weeks ago :dunno:
 
Yeah, you`ve gotta sort that ph out mate(I`d flush em, but I`m sure someone will have alternatives)! :peace:

yes a higher ph watering is in order

dont drown them though , its ok to feed lots of water when its time , but its not ok to feed em water lots of times (too often)
 
If your runoff pH is lower than your starting pH, us this equation:
Soil pH = Runoff pH - Difference.


'Runoff ph' minus the 'difference'= soil ph so that means 5.4 is the run off. the difference is worked out by the 'in' 6.3 - the out 5.4 so 6.3 minus 5.4=9

so 5.4-9= 4.5

You need some dolmite lime and sprinkle it on the top of the soil and use a fork to rake it in the top of the soil.

Dont just ph your water higher as it doesnt work like that.

it sure helps, just doesnt cure things over night, but then neither will the lime

i bring it back up slowly 2-3 waterings ph adjusted accordingly with no lime involved and it works for me 9 times out of 10 , sometimes the plants are just too far gone to recover

peace
 
6 weeks above ground.
Yes Ive got some issues with PH.
Yes Ive got 3 very sick plants.
But you know what its not all bad, these plants are budding up lovely. They smell bloody amazing.

Im all ears EVERYONE by the way for the best way forward with this ph thing :)
What should I set my PH to on the next feed?
Is it best to always feed until run off?
Is say a litre a day not as good as 2/3 litres til run off?
Someone mentioned if you dont run off, salt n shit can build up...

You're welcome, ffs
 
Ow Dude you popped back in.. so what ph should I be feeding now then?
You done the sums my ol mate but whats the last bit? :)
 
hey true,

the grow may not be as completely optimised as you would like, BUT the buds are determined to bloom anyway. Auto's are pretty resilient and I think you will get a decent crop from this.

pH is a funny thing. A lot of the pro-growers/breeders have 2 pH meters since they never like to put 100% trust in any single piece of kit. Some growers find out from their local water board about the water supply - often you get a 'sample analysis' which will show you some useful details (e.g. is it predominantly hard or soft water, approximate pH etc etc etc). Many growers like to allow the tap water to stand for a ay or two before giving it to plants, this allows dissolved gas, e.g. traces of chlorine, to disappear. Some growers like to use RO water (reverse osmosis) in times when they have worries about pH etc. Just adding an excess to allow run off.

For the next grow, you could simplify it a little by using bigger airpots with more compost. This might allow you to be able to forget about feeding (just add water) for the first few weeks of the next grow. Perhaps that would require you to feed them only during the last 5-6 weeks.

But back to this grow, I think you will surprise yourself and pul off a decent harvest. Good luck with it
