Ok thank you so much I really appreciate you pointing me in the right direction. Hopefully someone on here does outdoor as well. I have 6 autos in the tent gorilla glue and extreme Girl Scout cookies doing very well. Just so frustrating on my end to not know the problem to correct or fix it. Thanks again.

I'm no expert, but it looks like the new growth is yellowing and the leaves, for the most part, are normal green. Had a very similar situation where I had two plants that, after going through a 10 day period of rain with basically no sun, started putting out yellowing new growth. The first picture is the worst of the two plants. I showed it to an old timer that I know and he said it definitely caused by an iron deficiency. I checked this site and found the 2nd picture (noted as iron deficiency), and I thought it was pretty spot on. I picked up an iron supplement and have been treating them with it for over a week. One plant has completely bounced back and the other (see picture), isn't responding as well. Best of luck.

Just from the pics it looks like iron deficiency- but that could easily be done if the PH is not in the right range in the soil ? How big was the hole you dig? How much soil did you use?
Most important is Ph. I see other symptoms too - but I can’t diagnose without knowing the Ph.

Looks like you have nailed it yes mine look same way. What did you use for iron to balance it ? I’m afraid if I use wood ash or Dolomite it will take to long to act and plants will die by the time it gets into ground.

IGLM GDP Auto - 31 days from sprout

Hang in there Franklin65 they should bounce back and to me looks like they may start they preflower stretch very soon see white hairs . Just leave them be i think they will be good in a few days. I never fimmed a auto, photo i have. I only top and LST auto on my very strong looking stem/branch ones. Yours look good 
I just got one of these but it claims to kill like EVERYTHING! Gnats, spider mites, flies, aphids, just about any bug on earth smaller than a horse... Sounds like it is WAY better than spraying, dusting and all that. Great for an enclosed space like a grow tent or room. Put it in for 12-24 hours and remove. I gather not good for populated spaces (like in your home). Use where human exposure is no more than 4 hours a day. Saw a note on another forum where a guy swears it does what it claims to do. Saw another note where someone used it to "clean" plants/clones or such from outside sources (like a quarantine). They claim it doesn't leave any residue on the plants. Run under $10 at Home Depot & elsewhere and good for 4 months. Anybody here ever use them?

Could of been too close, could be under watered, could be overwatered, could be too hot of soil??
As SoOrbudgal has mentioned there are many things that can cause the symptoms you are showing in your three photo's.
To help in fixing what's wrong lets start with the first issue and work your way down. - Here's a Great bit of groundwork https://www.growweedeasy.com/wp-content/uploads/2014/09/cannabis-plant-problem-flowchart.jpg
* Move your light up
* Water as your plant needs it NOT a set amount (growing medium should feel dry or barely damp to at least the first joint of your index finger, - second joint is better)
* IF you're using a premix growing medium keep in mind that cannabis generally doesn't need additional nutrients at the start of it's growth. Nutrients already added to a growing medium are referred to as 'hot' and that is NOT something you want to start seedlings in.
Also for for future reference you may want to become a bit familiar with the plant leaf diagnosis section of GWE as everyone will encounter at least one of these issues at some point during their growing. That information can be found here: https://www.growweedeasy.com/cannabis-symptoms-pictures
Hope this helps. Happy Pharming!

Thanks - I moved the grow light further away a couple days ago now and the plant seems to be getting a darker green again. I am using coco and have dosed standard calcium and about half the recommended nutrients to start. I think I was overwatering - I am going to let the soil dry some more before I water again. Also this plant did get some heat stress for a day when I left it outside to get some extra rays. the other younger plant I have growing is doing just fine but it didn't get the same light/heat problems.
Also the seed wasn't identified when planted and could be auto or non-auto. Is there a way to identify if this plant is an auto without waiting for it to flower by itself? this is my first grow and I am using a seed I found in a bag of weed. I have spent the last 3 week trawling growweedeasy.com
many thanks

Hey guys, first post and also first time grower. In need of some help here.
The setup:
2xP1000 Viparspectra (22 inches above plants canopy)
Vivosun 6" exhaust (vented to the outside of the garage)
Fox Farms Happy Frog soil
3 Gal pots
2x hurricane 6" fans
homemade 4x2 grow box (2x 14x6 intake vents at the bottom)
plants are 4 weeks old (roughly)
I have the Fox Farm trio nutrients mix, but have only watered with the Big Bloom mixed with Cal-mag once (1 1/2 tsp cal-mag with 1tsp FF Big Bloom in 1 gallon of water pH'd at 6.3) the rest of the grow I have only used distilled water also pH'd at 6.3-6.5. Recently I've noticed the lower leaves tips turning brown and rolling backwards. Yesterday the lower leaves started turning yellow/brown. I'm guessing it's a deficiency of some sort but looking for some help identifying the deficiency and how to go about correcting it. The grow box stays around 77-79 degrees and around 50-55% RH. It seems like all growth has slowed substantially if any at all the past week. Any help would be appreciated. Thanks in advance.
