My plants started changing leaf color and it looks like a deficiency or abundence of nutrience of some kind, can anyone tell me whats going on here? Temp is good, and humidity is good also.

They seem to look good in the picture. If your see a light yellow color at the top itās probably new growth.

Okay,is that common to see in autos in full veg phase because they were growing in green

Green and upright is always good imho 
Make sure your light source is at the correct distance.

It could mean itās getting ready to flower or itās just growing. Iāve never had good luck in growing AK47 autoās, the genetics were unstable.

@truthhound they were pre 98 seeds and spent a long time in a dark cool place. They were bought in Amsterdam back in 2000 and got lost in a crisper bin in a refrigerator! I was probably lucky that they germinated. The only one that actually grew, got 8 inches tall and produced 2 grams! Lol!

Yeah theyve been needy, prob not best for first time lost 1 due to not germinating lost another a week and a half in and purged another because it was dying no matter what i tried and was way smaller, still got 6 tho

noob,
Iām going to make a few comments based on what I see, I have no idea of what your nutrient program has been so these are kinda general observations.
First off, a lot of growers do not understand that nitrogen METABOLISM in any plants is DEPENDENT on sulfur availabilityā¦an easy treatment to carry out would be applying a WEAK solution of magnesium sulfate (epsom salts) to your soil/media, give it 5 days and observe the plantās reaction.
You donāt want to go nuts with the magnesium sulfate because it will screw up your Calcium:Magnesium ratioā¦if you see results with your light application, you would know sulfur IS an issue. At that point I would make sure I was feeding some potassium sulfateā¦
Second thing I would consider is applying some micronutrientsā¦your looking for Zinc, Manganese, Iron, with a little touch of Boronā¦thereās a billion of them out there so I make no specific recsā¦

I use all advanced nutriants sensigrow A and B, B52, Voodoo Juice. Every 3 days (caps worth because i dont have a good measuring tool per 100ml also just started giving overdrive about half a cap per 200ml
)

You know, that kind of reinforces my suspicions about lacking adequate sulfateā¦the only sulfate I see is in your Sensi Grow part B. It says thereās 6% potassium derived from potassium nitrate and potassium SULFATEā¦you canāt determine exactly how much of each but because the potassium sulfate is mentioned AFTER the potassium nitrate in the derivation statement (āderived fromā') it generally would signify potassium sulfate is the minor contributionā¦Your micronutrient does contain Iron and Mangasnese but lacks the Zinc which is normally greater than Iron, Manganese, or Boron in micronutrientsā¦
Gosh, if you can purchase small amounts of Zinc sulfate and potassium sulfate (powders) I would add a pinch of both each time you watered , I believe youād see the change your looking forā¦
Thanks for showing the labels !

I am from north of Norway; I have heard a lot about things that has been made by Russian Scientists; and just now I heard that Auto Cannabis Flowers are made in labs in Russia in the 60-70 while they where trying to find out about the hippie movements in the states; so the Autflower plants are acctually not ārealā, they are made upā¦ by Russians.

Um, OK ā¦might want to read up on Ruderalis!

Iām. Autos were made by taking a hemp plant they found that flowers on its own timeline and .ating it with a cannabis plant which in turn made the cannabis plant pull the auto traits into the can plant. It is no way near made by Russians. I mean little man made crazy devices r made by Russians Russians may have found the hemp plant and mated it with cannabis but the way it sounds is like u think they added something to the plant genetically to make it an auto. I do grow autos but I find that they seem to lack a lot of things that photo type bring out like the percentage of return upon extracting. Lol. Autos give me a 5 to 8% return rate where as a photo plant will give me 12 to 18% return autos r still fun to grow and watch tho

Agreed @TheMadFlascher, some easy reading would show Ruderalis is native to Southern Siberia (about as Russian as it makes it) where it adapted its day-neutral properties due to the harsh environment and short growing season. Doubt Russian scientists were trying to correlate the hippy movement arising from Ruderalis autoflowering plants that had weak potency.

Perhaps the Ruskys couldnāt find Humbolt county or Haight-Ashbury on a map ??

Wouldnāt have helped LOL, all the best of Humboldt and the Bay was from labs deep in the Hindu Kush mountains, Thailand and other regions of the world where scientists were trying to create the perfect plant to make us Americans lazyā¦if only they succeeā¦oh, wait
