A little yellowing in the middle

[Finnicki]

On this 2 month old fem auto flower, I’m seeing a bit of yellowing. I backed the light off and is now 20” away. I water with CalMag once a week. Also been adding a bit of nutes. Using Atreum lights on 40% power. Thanks for any input. I also have kelp meal and worm castings but have not used either in this grow.

Don’t really see any huge issues, but it’s hard to tell with photographs sometimes. Maybe up the N a little.

Keep these they will help. Can't really tell need up close to a leaf to really tell what's wrong. But way it looks it's nitrogen deff

Thank you for the charts. I will switch to flower nutes next watering.

A little bit of yellowing in the middle of the new growth is not all that unusual.

As @Phytoplankton mentions it might be a good idea to bump up the Nitrogen a bit. The Nitrogen will boost the Chlorophyll and that is what gives the leaves and stems the green color. Plants must have Nitrogen in order for proper levels of photosynthesis to take place. And they need that little bit of Nitrogen even in flower.

Some of the Cal-Mag products have Nitrogen included, usually in small amounts, so you can cover both at the same time if you want.

Both GeoFloras have nitrogen in them. No iron at all however. Watering once a week. 7 gal Airpots Looking for a supplement for the iron now.

I added some Bloom and worm castings to each pot and watered each plant. Wait and see if color improves on older plant. Young ‘un is two weeks behind big sister and has no discoloration.

Here is a bud forming on the 2 month old auto flower fem. Trichs on the leaves already. Should be done by 6-1 methinks. Well, I hope so anyways.

My friend, kelp meal and worm castings are essential during flowering phase. If you say ya have them, then apply a Top Dressing of them. Pretty looking Budlets BTW

Using either of them, or both at the same time would not hurt and should be a bonus. The Worm Castings will add more microbes to the soil and the Kelp would help the overall health of the plant.

Top dressing would work but a Worm Casting and Kelp tea would be even faster. Plenty of web pages and messages about the amounts of each to add to a gallon, or per liter, of water.
