New Grower can someone help please

[mudduck3214]

So I've had a few successful autoflower grows but this one is giving me problems. My biggest issue is none of my plants are done. They have been going for about 130 days. The strains are 2 black Jack auto (sweet seeds) and 2 cobra (flash seeds). The cobras are in full flower nice buds that need to swell and finish, one of the black jacks has some flowers but the other has a few hairs and no actual buds starting. I'm running two 300 watt topled grow lights they are the green reflector series and ive been using grow more nutes. I quit using nutes earlier this week thinking maybe that's why there taking soooooo long. There tiered in 16oz solo cups on top of 1 gallon pots. And I'm using a coco blend. There light schedule is 18/6. Any help would be great.
Here are some pictures. This is the black jack thats not doing much. and here is one that's better and the 2 cobras on the right.

I would say that the 2 cobras are done for sure, the Black Jack's now that is a conundrum. My only thoughts are that you didn't get autoflowering seeds on the BJ's but that is just a guess. I have not seen any auto go that long.

If that were my grow room I would harvest the Cobras and try flipping to 12/12 to see what happens.

I would also try posting this same thread in the AFN 24 hour help forum and see if anyone else has an idea. Sending good grow karma you way and btw the cobras and BJ's look very nice!

My thoughts too maybe the black jack is one of there fast versions as they call them on there web site. When i grow true blue berry it never gets as full as a super skunk that i grow right beside the BB some strains will get rock hard nut never fat

Thanks for the advice guys. I'm going to let them go at least another week so I can continue flushing them. The other reason is there still throwing white hairs and none of them have started turning colors.
I feel like I have too much time invested to cut them early if there not done. If anyone thinks this is a bad idea let me know. I'm not concerned with room either because I have a cabinet for starts.
Also is it possible that being cramped and over heated in there previous grow box could cause this? I thought it would only hurt my yeild not slow them way down..

Oh yes too high of temps cause very slow or stopped growth. Photosynthis stops being produced at 95 degrees or so(depending on the strain) so if it is too hot your plants won't grow.

Also as stated above I think you should go ahead and harvest the Cobras because they look done. I would leave the Jacks for another week or so and see how they look then, because you hit it right on the head you have put too much time and energy to cull them early.

Thanks derek I think when the lights come on today I'll pull the cobras out and inspect them closer and get some better pics posted. I don't doubt your advice I just want to be positive before I chop them.

 

[derek420colorado]

Oh yeah for sure some more pics would help and you do want to make sure that they are ready. lookin forward to seeing what these monsters weigh

Derek is right and dunno why I didn't consider that sooner. I don't see you mentioning temperatures anywhere but definitely temperatures out of the zone will significantly reduce grow and ripening time.

 

[mudduck3214]

I hadn't really mentioned temps a lot because I don't have a thermometer. But they were in my garage in a cabinet from the first week of June till the end of August and it was usually pretty warm in there. Then I moved and built a room in my basement and then they started showing signs of improvement but that brings me to now...

My grow space still needs improvements like more fans and white paint etc, but the temps feel like room temperature to me so I think there OK now.
