Indoor yellow leaves

[regenon]

I have 8 auto haze in full flowering right now , one or two of them turned light green and seems to be yellow , should I change the pots ? the pots arent so big they are 25 cm.

I used some nutes but in very small quantity and water.


In the front are the super critical haze no auto flowers , they got some curly leavesand some of them are light green, I change the pots yesterday in 20 L bags hope they are come back to life .

Flash + Light make it hard to tell, how far along are they in flowering? I don't see enough buds to warrant the usage of the leaves yet, did you feed enough nitrogen through out the veg stage? Are they the flash line of Super Haze? If so, Stitch reccomends veg nutes through week 7 I think...

Are they leaves just "coming off" already? If not they can still be restored...

here are better photos

they are 1 month and almost 2 weeks , I didnt give them no nutes during the vegetation. the problem is that from a week ago i switched under 12 12 beacause I have the super cronic haze to in the tent and I needed to change it because they where growing to tall.

I forgot some big leaves where dryded so I ripe them off.

No nutes was the problem, that's an early flowering N def. Adding N now for the next 2 weeks will help some, but you can't add too much as it will cause your buds to turn out fluffy rather than dense.

The plant is using up the nitrogen from the leaves and using it to the form the buds, unfortunately the wasn't enough to support the plant. Do NOT rip the leaves off until they're crumbly and brown and damn near fall off, they still have SOME purpose.

I'd use a veg feeding for 2-2.5 weeks (at half dose sense you're already flowering) (until there's more bud sites, you can still feed nitrogen definitely at this point only being 6 weeks old) but do NOT do it for more than 2.5 weeks.

You can also foliar feed a diluted veg nute just spray carefully. The buds are still small enough that it won't cause rot or mildew if your air circulation is sufficient. I wouldn't do this for more than a week.

So to summarize, feed 1/2 str veg nutes with every watering for the next 2 weeks (I'm assuming that's only 6 waterings, if not cut it down to no more than 6 waterings) and foliar feed the upper (newer) fan leaves with veg nutes about 3-3.5hrs before lights on.

What kind of media did you grow in from the start? Like, what kind of soil?

I will start from tomorow to fed them with veg nute , I started in soil , I am watering them every 2 days , like 500 ml per plant.

Was a good soil with all the nutes in from biobizz but when I transplanted them I used another type of soil , maybe that is the problem.

I see deficiencies in Nitrogen, potassium, and calcium... That's a lot going on at one time.

What kind of soil mix are you using?

What are you doing to monitor and regulate your pH?

He's using the BioBizz which has enough feed for about ~14-21 days. I see the nitrogen definitely and the calcium possibly (I think I see the spotting? Not entirely sure due to the HPS lighting, again this should be reconciled with the veg nutes and normal tap water) but I don't see the Potassium def? What do you see that indicates that? I see the bit of curling and mottling in the third picture but I don't see excessive burning or curling. (I'm not saying you're wrong, I'm saying help me understand so I can identify in the future.. )

Could you get us some shots not in the HPS like you did with the one plant? The HPS I think is what is causing some of the confusion here!

What kind of nutes are you using?

That's the mix I'm referring to.

In the pic that is by itself in "post #1", the plants in the bottom left hand corner, along the wall, are browning and dying from the tips of the leaves inward. This usually means a phosphorous def.

In the first pic of the group of four, we have browning and dying along the serrated edges. This is usually an indication of either a potassium or calcium def. There's even one leaf that looks like a zinc def.

So I'm back to this:

Ahhh, I see now.. I didn't pay attention to the corners of the first post, should have looked at all of the plants.. yeah, those issues are all pH swings causing different lockouts. Otherwise there wouldn't be so many different deficiencies among the same plants. I still stand by the early flowering N def for the main yellow ones that are yellow from the middle up!

Go Joe Dirt!
