So, I come home from work, check on my ladies and find this on some fan leaves..


The first two are the new problem that I cant diagnose, the third is a pic of a yellowing fan leaf at the bottom of the stalk, though Im not sure what to make of it.


I soil grow with light fertilizer from a hydro shop according to their directions, 1/2 teasp. per 5 gallons.

The plants are vegatative with preflowers...


Please help, let me know if you guys need more info!

Nitrogen Deficiency. 1/2 tsp per 5 gallons seem like a very small amount. What brand are you using? I use BC Grow/Blossom/Boost and awesome blossom same order 1-3-6/ 3-0-2 /3-0-2 /2-11-11
Per gallon 1 tsp 2tsp 2tsp 1/2 tsp

These amounts are for the nutrients I am using but you compare the NPK (1-3-6 ext...) to your product.

Woah those are huge #'s. I see now why it is 1/2 tsp per 5 gallons. Such a high concentration will be hard to manage. If you are only using it at 1/4 strength I would recommend 1/2. Your leaf does look like it is missing nitrogen

It's hard to say. My suggestion is to fix one problem at a time. If you fix one problem the other one might clear up on it's own. If you change to many things at once you wont know what worked and what didn't The only exception to this rule is if the problems are unrelated. like nitrogen problems and bugs.

Fortunately, the leaves were just dying bottom leaves, as the yellow never spread, as well as the degeneration on the other leaves.

Im keeping a close eye on them, and so far they still look OK, except for the degeneration that already happened.

So, in a situation that sounds almost exactly like mine, if the yellowing has begun to spread to leaves which would seem to receive sufficient lighting, then it's probably a nitrogen deficiency, correct? I also use a 20-20-20 fert.

yellowing of the lowest leafs
can sometimes mean they need a transplant
other than that id be flushing then applying a good all purpose nute strong in nitrogen
all the best

The diameter of the pots is about 14", I believe, with about a foot of height. They are in Scott's potting soil and the plants themselves are about a foot tall from the top of the dirt. Should they be in something bigger? If so, how big of pots should I get to carry me all the way through harvest? I'm not sure what strain this is, pretty sure it's an indica variety, but it seems to be one with a very wide root system.

Youre in the wrong thread, this is my problem thread.



The plants are transplanted 100% succesfully thanks in-part to the GROWFAQ.

Transplanted into terraponic soil by supernatural, and using some gro and bloom terra from supernatural as well.

12"/ 3gal pots, they are gonna get a nice root structure in there, Im veggin them for a week before i flower them to promote more root growth, as well as blending in some bloom nutes later as well.


Tell you what it sure takes a lot more water for them now!!

Im still watering with extra nutes as mentioned earlier in the thread, and it just seems that there is no effect, the yellowing is getting worse on the one leaf its now practically dead.

The unknown degeneration is spreading... I think, or it was always on all of the leaves.

This is my first grow, and so far I have been very happy with the results, I plan on keeping a hold of one of these plants as they preflower hugely
