Do some growers oscillate the PH to access all the nutrients ?

Do some growers ( Hydroponic more so ) oscillate the PH from perhaps 6 to 7 ( and then 7 back down to 6 ) in order to access all of the nutrients shown on the image below ? Do they manipulate the PH to certain values at certain time to access certain nutrients at certain time of a plants growth , or do they constantly manipulate the PH up and down so that the the plant gets all of the nutrients shown below , all of the time ? Do the plants need all of the nutrients within a certain period of time , perhaps during a one week period ? Does a plant need all of the nutrients shown below , requiring constant oscillation of the PH over a one week period , every week ?

Does each species of different plants require a different profile of manipulations of PH ? ; if PH manipulation is every done ?

In hydro you often set it at 5.7 and let it drift to 6.3 pH. pH will rise slowly in a dialed in system.

Different plant species require different pH values for optimal growth. Like blueberries grow naturally in very acidic soil. pH between 4.3-5.5 is optimal for blueberries while 5.7-6.3 is optimal for Cannabis.

Plants need a complete plant food for optimal growth. But you will always have essential and non essential nutrients, same as with humans and animals. Cheers!

That's exactly what I do with hydro.
 
In hydro I alway set the Ph at 6 and walked away. If it drifted it drifted. When I topped up I'd set it at 6 again. When I dumped and refilled the reservoirs I'd set them at 6 again and walk away. The plants were always happy.

I wouldn't even bother trying to manipulate pH from this to that in a small grow. Any potential benefits are just not worth my time fiddling around changing the pH since they would be minimal at best. If you have a very large grow then a pH controller is probably a good investment.

6.4 regular feed
Every week or 5 days 5.4 for treat. How l grow! In flower!

Really, ld ph one plant if its all l had.

I do pH. I set it at 6. I just don't want to bother manually manipulating the pH to different levels. I set it within the range and call it done. But like I said, if you have a large grow then a pH controller can be used for that manipulation. On a large scale any increase in yield due to pH manipulation could be of significance. On a small scale any gains would be minimal if at all.

Now I'm just speaking of myself and my small grow. I try and do as little as possible. Maybe I'm losing out on a few grams here and there but I still end up with more than I need.

:peace:

I saw you ph ed, just didnt get the small grow scenario, am old and slow. Ill catch up sooner or later.
 
I swing mine between between about 5.8 and 6.5 in coco. I'm just mixing up small batches so I target around 6 but don't worry too much about being exact so I can hit that range. I tend to go a bit on the higher side during flower, looking to increase availability of p&k from my base, not sure of it does anything.
