Finding Ppm Sweet Spot in Flower

I am trying to find the ss ppm for my sour kush girls.

week 5 flower, and I had the ppm at 1400, I noticed that they were drinking more water than nutes. Tips were just barely burned....(ppm would slowly rise over the day)
I assumed they needed lighter nutes so I dropped it to 1250 ppm.

After a day the ppm was the same and the water level dropped a lot as well.

My question is is this how you find the sweet spot? Is this the goal?

After I add back water I also add back the necessary nutes(base nutes only I don't add back additives), to get back to 1250.

Hope this makes sense.

Thx

Is the goal to get them to eat and drink the same amt?

My girls look great and have a ton of trichomes.

This is the sweet spot for me is 1300 is my target but have had some genetic in the past that were
Nute hungry beasts, 1800 and they were like that all you got!

That is ideal but they change what they eat as time goes by so keeping it dialed in 100% of the
Time is dam hard, if you loose 10 gal from lets say 30 gal and it goes up 50 ppm then your
In the sweet zone, even 100 ppm climb is ok

This is my opion and what works for me, i like being alittle high than under but when its getting close to flush time
I let it drop off

Thanks hellraiser! Ok so a little more drinking than eating is ok. My plants are going strong now, my first hydro attempt!!!

Can't wait to fire these girls up.

I'm so addicted!!!!!

Less is more with feeding. I feed all my strains mid 800's or 1.2 EC and consistently yield very well. EC is only part of the equation when it comes to feeding as the actual mineral makeup of your EC dictates how well your plants will perform. No offense to anyone but if you think your strains do well in the 1000's of ppms, you've got some more practicing to do.

Good info, I'm a rook so I'm in absorbing info mode.

My plants are dark green, but not in terms of nitrogen overdose. This was the color I was shooting for.

At 1.2 ec would you say your plants are dark green, or a few shades lighter?

Does leaf color have any correlation with quality and yield?

Thx for the replies.

I may try lower ppm's next go around.

Hey homebrewer does your ec drop over the course of the day?
AK47 on harvest day below. Feeding levels never exceeded 1.2 EC. My EC doesn't 'drop' necessarily as the plants consume water and nutes in roughly the same ratios. My res is an adequate size to handle 6 plants of that size in rockwool with the number of times I flood per day. Weekly res changes.

:lol: coming from a guy who doesn't know what pH his plants should be in flower makes me wonder why you've wondered out of the newbie area. :confused:

I'd love to see full pics of the strain at harvest that enjoys those feeding levels with no burn. I'm not calling you out, i'm honestly curious.

Anything 1300 - 1600 is pretty high in my opinion. Strains also have a lot to do with it too. Some strains can take a lot of nutes and some cant. Over feeding will cause you to lose lots of water.

ok so when my plants hit week 6 they kicked into overdrive. ph has been crazy, as low as 5.2 after adding 20mls to 5 gal of water. ppms are at 1800( they munch on 300-400 a day) I have no doubt its them lowering the ph due to insane P, and K uptake. I have never vegged to 8 weeks so my questions is do i let them keep the ph in the low 5's or do i Napalm them with 15-20mls of Ph up EVERY DAY to keep it at 5.8.




"Your res is too small and your ppms are too high. Things are far from 'optimal'"- homebrewer
Yeah, but showing up just to criticize is all that bored lonely bastard ever does. I've been around since the "overgrow" days you dildo, just cause i'm trying a new method and learning something new doesn't make you Jack Herrer. With great detailed information like the kind your provided above, I'm baffled at why i didn't solve my problem and you didn't get your own section in this forum! The "Beaver" is right, to each his own so Start helping people with THEIR grow, instead of trying to convert them to your backward ass ways. BTW, yes i got the same if not more yield with no burn at 1600 ppms. I would post a pic, but i could care less what you think. Cheers Mate!

yeah, but showing up just to criticize?? I've been around the block, and im still absorbing info! bottom line is this business is full of opinions. take what works for you and apply it.
Thats RIU for you, lots critical people here. If you dont want criticism then you gotta find a new forum. I'm part of another message board but still use this one too. Alot of growers hate this place thats why they start there own message board. Hellraizer has been around the block he knows how it goes one rule all growers share is " grow what way works best for you"
