Please help...Kushberry problems.

[I Forgot]

I'm 3-4 weeks into flower. I'm using ff ocean forest, 1000w hps, ff big bloom. I have read the plant problems threads. I'm kind of stuck and want some input to help me figure out whats happening or if I'm worrying for nothing. My tops are starting turning light green and the fan leaves are yellowing and starting to drop off. I'm thinking either mag or nitrogen deficiency but not exactly sure. This my 2nd grow so I consider myself a newbie and still learning. Any help would be greatly appreciated. Here are some pics.

The picture's at the bottom of your thread look ok if you are 4 week into flowering then you are half way there.The plant's are takeing all the nitrogean from the leaves this is normal for the leaves to turn yellow.I would advise flushing the plants with the ph you have been useing so far just water it may have a salt build up but they should be fine..............tyke....

Yep, they are yellowing from low nitrogen. It's a little early yet, so I'd hit them with some veg nutes for the next two feedings, then switch back to bloom nutes. On your next run, stick with the veg nutes a little longer. I used to make that mistake too, switching to bloom nutes as soon as i went to 12/12, then having my plants turn yellow early. It has a big effect on yield, way more than i thought it did, until I had a run where i kept them green til the very end. They filled out alot more, for sure(at least 50%).

I just watered today with bloom nutes before I read your suggestions and was wondering if its ok to foliar feed with veg nutes till the next time I water with the veg nutes.

It looks like someone snuck in to your growroom and cut the ends off all the leaves on your plant!!

A buddy said to try it to get light down on lower buds. Bad idea. It was a learning mistake that will never happen again.
