Yellow leaves/Brown Spots/Bottom Half

Greenhouse seeds White Rhino, see sig for more details information on grow.


All 7 of my plants started to yellow by the third week due to

1. lack of space in container
2. need of nutes

I transplanted all plants into a bigger container and fed all plants the following (this is their first feed ever, all plants are in Happy Frog soil, ph always adjusted to 6.5):

Per gallon:
~13ml of Liquid Karma
~8ml of Hygrozyme
~5ml of Fox Farm Grow Big


After 1 week all plants tripled in size and turned a nice dark green color except for the two White Rhinos (pictured)

They have been heavily watered twice since with straight up 6.5 ph water... Any ideas as to what they are wanting? If i follow the sick plant chart its telling me they need N, which i kinda find hard to believe.


HELP!

Any questions?
Need more pictures?


ask away


Thanks


pair of WR in question

pair is in the background



Additional information:

All plants are on day 32 in the pics

All plants needed to be transplanted out of the 1.5 g pots into their final place (3gal grow bags) except for the two WR which have SIGNIFICANTLY less roots

the only thing i can think of is N and or Mag Def or they are really sensitive to nutes

this one has me stumped a bit as all the other strains are perfect


I think ill give her a shot of Urea and Epsom Salt


should i do this along with my regular scheduled feeding of

Liquid karma
Hygrozyme
and grow big?


or just the two (urea/epsom salt) alone?


any other suggestions/comments/etc?

its much appreciated

Kinda N and mg defic but I thought wr, like a lot of the other white family, didn't like a lot of nutes so i'm thinkin maybe overwater due to
1. lack of roots
2. roots, but roots that not efficiently taking up water due to could be several conditions.
Containers are small enough as to prohibit to much standing water in the soil but the soil definately looks a lot wetter on top than the other healthy plants in the same sized containers.
if you've been watering the same this means the roots are distressed.
Hard to believe the hygrozyme and LK isn't helping those distress roots but maybe add some hydroguard or h202.
Maybe repot into a lighter soil, like with chunky(er) perlite.
IMO don't add the urea, a higher nitrate n formula would be better.

this is good advice imho, i agree with white typically being extremely sensitive to nutes but i gave her a very mild formula like the rest of the strains at week 3. she continued to stay yellow, the others exploded with growth and greened right up


grrrrrrr

Went ahead and fed these girls a more potent amount of ferts a couple days ago... they seem to be perking up a bit. The roots most certainly have grown, but overall these girls are a lot further behind than the rest of the pack. Im guessing they are about 2 weeks behind. Bummer.


day 36 pics

So with the added ferts and a couple days have gone past... what do you guys think?












overall pics for comparison to the rest

I'm having problems with browning and curling. I just switched to Fox Farm Grow Big. I fed them and did not like it at the heavy feeding suggested. No more Fox Farm for me.
peace

calicoli06, did you gradually ease into the heavy feeding? how old are the plants? what strains? temps? ph? etc. need a lot of information to comment.


curling typically shows heat stress or over/under watering

the plants are these. http://www.icmag.com/ic/showthread.php?t=61371
Did not ease into them. Was using MaxSea before this feeding. Can't blame Fox Farm though cause I forgot to PH the water which I never have to do with my other nutes. :bashhead: . Also I knew it would be risky with the heavy feeding when the ppm meter wouldn't read it. :bashhead: My meter only reads up to 2000ppm. I just thought my plants were ready for a big shot.

in my experience the fox farm nutes lower PH significantly, therefore it needs to be adjusted back up...


when using new nutes its always good practice to ease them into it, half the suggested heavy dose for plants that size...



I'm not a big fan of the fox farm nutes, i had it left over from my last grow... ive since switched over to botanicare products which seem to be less intense... therefore more control over dosages.


i didnt buy the pro grow pro because i didnt think they would need the nutes by the time i started flowering (i got the pro bloom pro). but they asked me for it so i gave them what i had for the veg cycle
