Week 4









Week 5

This week was terrible, i think i fail ;/

Nice set-up!
Looks more like Ca than Phosphorous in the one picture. May want to add Cal/Mag.
What is your medium? are there other signs of weakness? Because plants look healthy overall.
Is there a reason that you use "Very very little" fertilizer?

[Critical]

Thanks
I'm use soil and perlite 50/50. Last time when i growing was overdose fertilizer i think, so now i'm use not too much i think ppm 350, couze afraid to kill them, i'm paranoic or confusing and if something wrong i think they sick. ) I will fill up this journal for more and more.

[Campesino]

It is better to run the right EC, 350 is pretty low and may contribute to deficiency symptoms. Rather than diluting so much, I suggest measuring EC or PPM and maintaining a target.
As long as you are measuring and know the run-off values you won't risk burning your plants. An overdose of fertilizer dose not lead to an actual overdose... what it leads to is an inability of the plant to drink. Fertilizers add saltiness to the water and if it is too salty the plant can't get water and is "burned". You need to make sure that the plant can drink by providing the correct EC (or PPM, but EC is better). Just playing it super-safe as you are will lead to deficiencies and disappointing results, which based on your description, is your current experience.
Where in the world are you if you don't mind my asking.

Thanks for advice Campesino. I looked water bottom of pots and was the same ppm 350, but PH was 7.2... I first time grow in autopots, i think there is problem ,cant absorb fertilize.. I'm using tap water ;/ need to wait rain. Everytime started problems when i start use nutrients..
Sorry for my not perfect english

[Campesino]

No worries, just curious!
I still say that 350 is really low and probably contributing to deficiency symptoms. I understand that you are cautious with nutes, which is good, but need to find the balance.

Wow looks more like a sea of green than scrog territory to me. But In that regard im new. But very nice looking setup.

[Critical]

Thanks, but its first grow in AutoPots , so a lot of things must to do

[Dutchman1]

Looks like its going to get very crowded in there. Thats alot of plants for that area. Youl have to do some good trimming and air movement will be most important.

[Critical]

Thanks for looking. Ye now its for 2 lamps for now, but i will add soon 1more lamp and 1m2 add. I'm Using to Fans , one from outside and another one In, i will add fotos soon. I Think about scrog, little toping if its posible now? or its too late?

[Critical]

Little Update here with defencies. Every time starts these problems , when start use nutrients.. But i think its PH prome, couse very high was.

[Redwasp]

You say your ph is really high. You need to fix that. Ph can cause what appears to be nutrient deficiency. Because they cant absorb nutrients. My water always starts at 8. When i add nutrients drops to 5. So when straight watering i have to to lower it. When adding nutrients I have to raise it. Started doing 2 5 gallon buckets at a time. Will save you alot of time. When adding nutrients always test after you add them.

[Redwasp]

Hey whats up?

Week 5 its terrible for me, i think i fail my grow, Ph and nutrients defencies affected my plants and i fail i think, i'd like vegative more, but when i look i dont know they give result or not. Added extra P-K Cal-MAg with rain water. Before when i grow, dont used PH metters, ph up, ph dow, used rain water , was perfect. Now tap water and started these problems. What do you think it will recover these plants or not ;/ couze defencies very big i think.
Best regards

[Critical]

Thanks again for advice, understood i will increase it for next watering and how long it takes to see diferenses one week?

[Critical]

And if i will water with 6 ph couze its jumps every day about 0.2-0.3 . Plants will take nutrients till it jumps 6.7-6.8?

[Campesino]

Yes, you should see improvement within a week.
If pH is climbing in the media you can lower the inflow to the bottom of the range as you suggest. Perhaps 6.0-6.3 for inflow and continue to monitor. I would avoid putting in inflow lower than 6.0.
Cheers!

[Cows]

6.8 going to use g.h this is an auto

[Critical]

you mean in auto pots its jums to 6.8ph, sorry dont understand?
