Hey WH,
So far they are pretty hearty and not showing any nute burn that I can tell. Some of the lower leaves are getting brown and brittle probably due to lack of light and nutes being directed to growing shoots. I let them get up above 1500 PPM only when I got busy and didn't check the PH/PPM for a few days.

These BDs seem to take alot of abuse with nutes. They were the ones that I grew originally when the cola crashed down prior to harvest. That was when I didn't have a PPM pen and just mixed according to the directions per Botanicare literature (which I believe is too aggressive).

So far, so good. I am changing nutes today and gonna try to report PPM/PH numbers as often as I can... hopefully daily.

Wow, gotta love Mr Clipboard.....:D

There has been a Res Change and new nutes for the (anonymous, unnamed) girls. I snuck in just before "lights on" and snapped this pic:

BD1 Nutes:
3 gal RO water = 10 PPM
+ 2ml/gal Zone = 10 PPM
+ 10 ml/gal EJ Microblast = 184 PPM
+ 10 ml/gal CalMag = 615 PPM
+ 15 ml/gal PBP Grow = 1378 PPM
+ 6 ml of UP to get a PH of 5.8

Added it all to the res (which always has a little residual solution left in it) and PPM was 1266. Not what I wanted so I added 15 ml more PBP Grow and final PPM = 1427, PH = 5.8.

BD2 Nutes:
3 gal RO water = 10 PPM
+ 2ml/gal Zone = 10 PPM
+ 10 ml/gal EJ Microblast = 160 PPM
+ 10 ml/gal CalMag = 596 PPM
+ 20 ml/gal PBP Grow = 1527 PPM
+ 5 ml of UP to get a PH of 5.8

Added it all to the res and PPM was 1388. Damn near perfect. Final PPM = 1388, PH = 5.8.

And for those that are interested, I took a couple of shots of their roots. Pretty white and strong although parts look a bit brownish, which I attribute to the organic micro-nutes. You'll see in the shot that brown residue in the reservoir.
If anyone has a different opinion let me know...

Oh, BTW - still got those damn gnats so I added 1/4 of a Mosquito Dunk to each res to help fix the problem (hydro store didn't carry Gnatrol, said they had same active ingredient). If anyone develops a gnat problem, check out this link and LW's idea on how to get rid of those little fuckers....

MVP.....what day of flowering are you at? Have your plants been on CalMag from the start here? May be time to start backing down your CalMag. Might be the lighting but those are some DARK green leaves.

Hey....you could leave out the extra pbp and start up some LK or sweet.....just thinking out loud....well thinking in type....:D

Actually still in Veg - using Grow nutes not Bloom as mistakenly indicated in the retro post. I'm trying to fill out the screen with growing shoots before flipping them over to Flower (that is also part of why I started flowering the MK clones from the cloning log - so I could have some buds while waiting out the BD SCROG).

Regarding LK/Sweet, I was thinking of following Latewood's method - adding the LK and/or Sweet during top offs - when the water levels fall. I'm gonna go stick my head in there now and look at the leaves. It's probably the lighting (so friggin tough to get shots inside a closet), but I wanna make sure that its on the right course.

Another post momentarily after I check out their color.....

If they are in veg i'm happy with their color..:thumbsup:...must be the lighting.....sorry if i scared you. :( I'll get your feedback about latewood's method....never tried it myself but always like to hear about stuff that works. ;)

And for those that are interested, I took a couple of shots of their roots. Pretty white and strong although parts look a bit brownish, which I attribute to the organic micro-nutes. You'll see in the shot that brown residue in the reservoir.

Mine look alot like that when I use Liquid Karma. It has chunks that settle to the bottom.

LK does it to mine too....rinses off if you are gentle with the roots....but I don't really worry about it.
