Hello there autoflower lovers! I came here in search for your help. My 6 week old heavyweight seems to be having a little bit of a issue. It's been budding for about 2 weeks or more. Here is what I am using for my setup:
450w led with 300w led side lighting.
Promix all purpose soil
Distilled water with 3ml of calmag+
Flora nova bloom since week 3-4 of growing. Did not use any grow nutes just bloom (Lucas formula). At 3ml per gallon right now.

Here is my problem. I noticed some yellowing and some nute burn tips on my leafs so I lowered my feeding to 2ml per gallon once and since that it has been getting more yellow and worse. I added the regular 3ml per gal and fed here 2 days ago and added a little nitrogen. (Bat guano) I'm not sure what this is. My runoff pH is at 6.0 6.1 and my intake pH is around 6.4 6.5. Do you think that what I did is right? Or should I flush? I have the same strain in a two gallon container and it is eating up nutes since week 2.your website is the best out of all and I would love your expertise in autoflowers!!! Thank you in advance! 20150202_145849.jpg20150202_145818.jpg20150202_145802.jpg
 
I've got a fast and vast going at the moment but it hasn't had that issue. I've seen yellowing like that before but it was on a plant that had spider mites. Most likely not that but have you checked on the underside of the leaves? I'm sure someone who's more experienced will drop in to help you :)
 
I think it's an N deficiency and should give her more N.
Because those tips don't seem like nute burns but rather just dying.
Could've been iron but then the leaves would be yellowing from the inside out.

at least to me it appears she's short of something rather then has too much.

Thank you for the input! I was thinking the same thing last night when I was watering the small guy. I noticed today that the leaves where not as yellow and are getting greener. Another question is should I pick off the leaves that are shriveled up on the bottom? Again thank you for the responses. I'll be sure to update some bud pics in a little while!

Thank you for dropping in!! No I have not checked for spider mites yet but I will once I get home from work! Again thank you!
 
I forgot to mention I have vipar LED lights a 2x2 5w and a 3x2 5w and they seem to be working pretty well! Do you think it will be enough to finish flowering? ? Thank you AFN!! I am also attaching a pic of buds and closeup on some leaves. 20150204_002516.jpg

Yes don't leave leafs lying around always make sure to keep things clean and tidy to reduce chances of disease and molds forming!
