Can anyone pin-point this??

So, Ive read the threads on diagnosing your own plants and have looked for people with a similair problem, and feel like I have narrowed it down to a few possibilities. PH, Nitrogen, and possible root-bound..... I know, I know 3 very common problems that are easy to fix, Im just wondering if any of the guru's on here can look and know which problem is causing the leaves to lighten. Im still seeing some growth even though the leaves are yellowing so Im not sure if the roots are bound. Heres some backgroud:

-Been vegging 5 weeks
-Vegging under CFL's (unfortunately couldnt hash the cash for a MH this go, will flower under HPS.)
--The babies are in 1 Gal grow Bags, and have been for 5 weeks
-in a soil mixture of FF Light Warrior and General Organics "ancient forrest"
-temps between 67-77 depending on time of day
-Humidity 35-55%
-Before last friday had not tested PH of water assuming it was ok. It was not so I adjusted and watered with 6.5 PH water on friday. The run-off of that water was right around 6.5 ph so I am assuming my PH is okay?
-Every plant has secondary growth and the "nodes" you look for before you switch the lights

Here are some photos so you can see what im talking about. The one of the group of plants was taken 2 weeks ago before I started noticing color change. The other pics were taken this morning.

I consider any feedback helpful, Thank-you in advance

The only sure thing I can say is to re-pot them, mixing some guano and worm casing into the soil this time. This could be N deficiency or also Fe(Iron) deficiency as well as clogging of soil, or root problems. If you re-pot them with new soil and nutes you take care of all of these points and give the plants a boost.

How are they draining?

It's actually Phosphorus, Sulfur, maybe Iron.

Definitely some pH issues, but maybe in the past, you need to get her straightened out with the NPK profile.

Nitrogen deficiency will start lower on the plant and work up. Your leaves are coming out yellow. This indicates an immobile element deficiency (along with the necrotic blotches) and Phosphorus is the most likely element in short supply.

You can amend a little high phosphorus guano and some Epsom salt into the top inch of the soil and water through it. Or you can pick up a balanced organic nutrient (like a 2-2-3) and use that to balance things out.

Looks like an overall nutrient deficiency. I'd say the nutes in your soil ran out 2 weeks ago.

also looks like overwatering with the leaf tips curled down.

d00d I did all of this....but that soil is sitting in trashbags (go figure) and im wondering why da eff my plants arent growing in this bad ass soil I made?...then I realized my plants arent in the bad ass soil yet, just light warrior and ancient forrest. What the hell was thinking haha this whole time im forgetting im not in super soil yet. wow.


Muffy, probablly the best observation. Im doing alot of stuff but seems I forgot to actually be feeding these guys enough. Realized shortly after i posted this thread it could just be that these guys are real hungry and ran out of nutes weeks ago, which is why they started green, then turned yellow.

I am using a very close soil to subcools mix....but completely forgot that is sitting in trashbags right now until I repot in 7 gal smart pots. The only thing I have the plants in now is light warrior, mixed with Ancient forrest...whcih is the TITS btw. I wasnt even giving the plants the bountiful feast I made for them, what a dummy move hahah. Ill be giving these guys one more water with some food, then making their new homes this weekend. In my soil mix I think im going to throw in some of that Organicare "pure", the granulars with the pink label, comes in a bag. Also wanted to throw in some sort of trace mineral powder, thinking azomite or pyro-clay, Any thoughts? snowcrash?

r8r-I could be over watering, ive been trying to get this dialed down as well. Im watering 2 "red party cup fulls" (I think they are 16oz per cup). I water about every 3 days when the soil is looking dry before leaves droop. Do you think im watering to often given my climate?

Thank you for the feedback guys!

As mentioned, it looks like they are hungry, overall, generally underfed, whether the nutes are unavailable to them, from poor watering habits, or simply not there. At any rate, they are ready for a transplant. Being in 1 gallon bags, is a little small for this stage. I've used grow bags before, and don't like them, because they make it difficult to water thoroughly, having a tendency to leave dry spots, due to the water running down the edges of the bag.

If I were you, I'd start using a weak nute solution(high N), and watering in two segments. Water the first 16 ozs, then wait 20 minutes or so, and give them the other 16(or a little more). That'll make for a more even saturation. Transplant as soon as you can, and you'll be surprised at the difference it'll make. Also, go with at least 3 gallon pots. I use 4 and 5 gallon pots, and want to step up to actual 5 gallon buckets. What I use works great, but I still want to go a tad bigger. Bigger is better, trust me. I'm too tired to type rthe reasons, atm. Wait til I have another coffee.lol
