QUESTION FOR THE KNOWLEDGEABLE EXPERTS

[ghuser113]

Hey everyone how’s it going? I hope all is well in your garden. Had a Q for the pros out there I have some nirvana Chrystal going and ima about 36 days in to flower give or take a few days they are about 3 to 3.5’ tall under a 1000w hps and I’m using gh nutes grow micro bloom Koolbloom flora + flora blend and my PPM is about 1100 now in a drip systems the water farm from gh I’m sure you are all familiar with those WAS WONDERING WHAT MY TARGET PPM SHOULD END UP BEING I’m using
0ml grow
15ml of micro
30ml bloom
0.1 Of flora +
5ml of flora blend
7ml of koolbloom to a 2 gal rez
Plants look fine but were wonder what the pros that they could handle me myself maybe thought 1500 ppm? To high? To low? What do you guys think? Thank you all, you guys are great and full of knowledge. O YEAH USING RO WATER

Slight tip burn is a way of gauging maximum nute amount. If your plants aren't showing any sign of burn, up the strength a little but IMO, don't go 1500 in a single feeding. Back off when slight tip burn is achieved. Some peeps don't like to drive with the accelerator on the floor so use this tip with caution.

BTW, ppm is a tricky measurement to gauge nute strength. There are several scales for ppm. In extreme circumstances, you and your peer might be talking as much as 600ppm difference if your conversion factors are different. There is one EC. There are 3 different conversion factors for ppm. Knowing your particular conversion factor helps when discussing nute strength in TDS/ppm.

you're already into week 5; many people I know top out their ppm around week 4, but it all depends on what your strain likes and how long you plan on flowering. I would bump it up to 1300 ppm (on a .5 conversion from EC) and see what she does. Don't forget a week or so of flush before the chop, which on an 8 week bloom schedule means that you have another week or two of food. Otherwise DiscoBiscuit just gave you the keys to the kingdom. Good luck!

How do I know what my converstion is i have a oakton 0-1990 ppm pen?

 

[DiscoBiscuit]

How strong is your calibration solution?

 

[humble1]

oaktons are adjustable, but I can't remember how to check them. your manual should be of some help.

 

[ghuser113]

If i were to go to 1300 should I used bloom and koolbloom to get to my target or should I use an over all nute rise like adding more bloom koolbloom micro flora+ flora blend?

 

[humble1]

bloom and koolbloom. you don't need the extra N this late in the game.

 

[fsttimes81]

N in bloom ferts?????

 

[humble1]

yes, if he did an over all nute rise he would be adding back more micro (has N), flora blend (more N) and floro + (more N). Especially with GH nutes he doesn't need more N this late.
check out "The Recipe" over in REZ's forum.

Awww!!! It was a miss read, I thought you were saying bloom and koolbloom were high in N...lol my bad

Cool yall are great think I'm on the right path now, NO more micro, flora blend or flora + correct?
