Normal or a problem????

This is my northern lights plant that just finished 4th week of flowering. The leaves are starting to yellow, but I have also heard they do this when the get close to harvest time.

Is this yellowing normal for 4th week of flowering or is this some sort of deficiency?

I am thinking Mg deficiency because the leaves are yellow, but veins are green and since 'end of flowering' is more like 7-9 weeks, not end of 4th.

Can someone help me diagnose this? Thanks!

are you feeding them some flowering nutes?

newbie, but i believe it's pretty normal as the plant gets further into flowering.

as long as other leaves don't turn this way. you're golden

Yes, fox farm full strength.........tiger bloom and big bloom. Also, fox farms recommends a little big grow during this stage of growth.

My water is PHed to about 6.5 and I added nutes slowly to reach full strength.

About 10 minutes ago, I added 1/4 tsp of Mg(epsom salts) to 1/2 gallon of water and watered my plants. I watered this morning, so I didn't really WATER water them, just topped them off.

We will see!

the epson salts should cure your Mg deficiency, its definitely not nitrogen yellowing and isn't normal for 4 week flowering to occur. You did the right thing, now wait a week to see if it helped.
