Today marks the fifth week of flowering and I noticed that the leaves near the bottom of the plant are beginning to yellow. Is this normal or something to be concerned about? I changed the reservoir a week ago and added an extra tsp. per gallon of Ionic Bloom (bottle recommends 4 and I put in 5). The pH checked out although I'm yet to check it today. I understand that towards the end of the life cycle leaves naturally begin to yellow, however it seems like there are at least a couple more weeks left (1st orange hair seen a few days ago). Thanks in advance for any advice. Here are some pics.

Some shade-leaf yellowing is normal. It happens when you change to bloom nutrient. It has little nitrogen in it which plants use in the growth period..

This is a possibility:

<P>That link didn't help me at all. The only thing I want to know is if this is a serious problem and what I should do about it if it is a serious problem. The link essentially said nothing but nitrogen deficiency and wasn't very specific about that.</P>

Here is a close up of the leaves.

This is not a problem.That is very normal at 5 wks flower,some time i see this at 4wks.these plants do this near the end of flowering,even outside with no attention they will do the same.Nice plants.

Thanks for the advice Ron, I just ordered a 30x microscope so I can check out those trichomes. Hope to have a very merry christmas, you do the same.

this exact same thing is happening to my outdoor plant right now, at first i began to worry about it but ive since realized that this is completly normal as the plant is taking nitrogen from the fan leaves to focus towards the buds the result of this is the dying off of those fan leaves
