First post on this forum guys. Im kind of a newbie. Third grow thus far ( If you'd even count my first :P ) Working with 1 feminized ak, 1 feminized el dorado, 1 feminized blackberry and 2 feminized kaya golds. They are 2nd week into flowering. Having a terrible spider mite problem which im starting to tackle ( Fingers Crossed) But really curious about all this yellowing taking place. Not too sure if the yellowing is the result of the spider mites. Also seeing a little bit of browning on some edges and some brown blotching on some of the yellow leaves. Almost looks like nute burn? Any help would be much appreciated.

Did it start yellowing from the bottom up towards the middle? Looks like what mine did when it needed some nitrogen.After I fed it it was green again with a day or two. Also I think furt burn would be more spotted.

[ellochello]

yup the yellowing only started from the bottom now is moving up the middle. Do you think the spider mite problem i'm having would cause yellowing? This was my first year dealing with them so i'm not too sure. And if it is a nitrogen def, will feeding it higher levels of nitrogen interfere with flowering since flowering ferts tend to contain more phosphorous?

[ellochello]

Any other tips anybody? Or good ways of getting the nitrogen back up without interfering with flowering?

[lafurnace]

You still need a little nitrogen when you flower as long as its not as much as you gave it when in veg. The NPK ratio is about 2-1-1 for veg and 1-2-2 for flower. So maybe get 5-10-10 and try a 1/4 of the dose to start with see how she takes feeding.

[ellochello]

ya i figured something along those lines, ill start out with small doses. Thanks to everyone for the help.

ok guys it seems that my problem is getting worse, my spider mite problem is just about taken care of ive added some nitrogen to the mix and now im seeing this.
