Does this look right?

Hello all...

Northern Lights auto, 3 weeks into flower, feeding with Bloom since flowering started, and the large fan leaves are turning yellow. Buds are developing normally, with pistils still white. My concern is with the yellowing leaves, and my best guess is that the flowers are drawing nitrogen away from the leaves. Any help/opinions would be appreciated! Apologize that some pics are turned....

You have critters eating yer leaves bud

Some lower yellow is normal, looks like u need a bit of added P in yer nutes

 

[daveclark]

No critters I can see with my loupe or microscope...all leaves around the buds are bright green...it's the older and larger fan leaves which are yellowing...

If its yellowing from bottom upwards, nitrogen deficiency.

As its in flowering you do need less nitro so that makes me think maybe its a lack of phosphorus, just like Chris said.

what nutes are you using at what measurements?

Since flowering began, I'm using Dyna-Grow Bloom 3-12-6 mixed with rain water at 1/4 tsp/gallon

Try 1/2 tsp per gallon and see how it does. Alternatively if you have the other bottled nutrients, you can add 1/4th tsp of whichever one has the highest nitrogen number (the first number).

Thanks for the responses...I will start using 1/2 tsp bloom and 1/4 tsp grow and see how it goes...

Cut my 10 week old WW this morning...

Looks good, you're not drying it out in the open are you? Usually drying is done in the dark as light degrades THC when bud is being dried.

I dry cut branches hanging in the dark (garage with windows covered black plastic) with a fan to help the 2 week process.
