Hi...
And here we are again...
Like every round I have difficult times...
Last few rounds I manage how to make big healthy plants/roots in rockwool slabs in veg.
So I went to bigger space with bigger reflectors and bigger plants to push my limits.
Good to know is I make really healthy plants and roots in veg with 500ppm 6x daily with huge runoff I was recirculate 30gallon rez 10 days replace at max.
I recirculate 30gallon rez for first two weeks in flower with 650-700ppms the deficienties show up very rapidly so I push to 800 at the starting week 3... the defs were worse...So I start use pure R/O without tap water for more space for nutrients.
Im at 1100ppm with 850-1000ppm runoff at week 4 it depend on radiation. And didnt saw much improve with 1000ppm yet... Few plants looks great in lower radiation places but majority have huge defs. This is new for me Im seriously worried I was thinking about lockout or wrong badge of nutrients.
I make my best so I stop recirculating rez and use 10% runoff like the pros with R/O 1000ppm.
I think I should use 1000 ppm at week 2... and I guess I wouldnt see so much yellow leafs.
The question is how much PPM I should use now.
pH system in my hands is not ideal but I grow big nice frosty buds with it in the past.
In veg and stretch phase Im around 6.4pH
In bloom Im at 5.5 pH in slabs... the rez pH the whole season is at 6.0pH ... plants are eating and chasing pH isnt worthy... they are happier with stable pH rather when I was chasing perfect point and stress them with unstable pH.
The question for you guys Is....
Have I really that hungry plants or I missing something? I really try to be a good grower and I have hard time to push PPMs so high im worried about roots and nute burn!! Roots are the hearth of the plant! and I know I can have still high yield but with reasonable PPMs.
Typical N def are all over the plants and at the top I can see P def.. purple leafs like in the flush phase! damn with 1000ppm... is It possible? Truth is I never have so many big plants and so good enviroment.
Im almost sure its not lockout and nutrients should be normal.
I always thought anything above 1.5 EC is too much.
But that typical N def with 1.8 EC is overhelming they just wanna more food.

General EC feed strength guidelines
- Propagation: 0.5-1.5 EC or 320-960 PPM
- Underfed Mature Plant: 1.5-2.0 EC or 960-1,300 PPM
- Optimal Range for Mature Plant: 2.0-3.6 EC or 960-2,300 PPM
- Too Much: Above 3.6 EC or 2,300 PPM
- Plant Damage: Occurs at or above 5.0 EC or 3,200 PPM
