Nute Problem 20 days to go?

[manels1111]

Any ideas on what is happening to my plants. Basically it started two weeks ago. The major fan leaves from all different sections of the plant starting turning light green and slowly to yellow from the the tips going in until the whole leave is unformly yellow. Then it starting spreading to the smaller leaves. The fan leaves stems are dark purple. It started on a couple plants and has since started on about all 10 of my girls. The sickest plants fan leaves are starting to die off. They don't really get crispy or anything just stay yellow and then the stem detaches form the plant.

Background info.

10 lowryder #2
600w hps and 440w hps
Temps 70 degrees
Soil Fox Farm Ocean Forest
Full line fox farm nutes
PH meter says runoff is 6.6 and I calibrate it.

They are 47 days old with about 20 more days to go. I'm afraid they might not make it though its happening fairly slow.

I have a feeling its N defiency but I'm using the full line fox farm nutes.

2 waters ago I gave them a flush with clearex in hopes it was a salt build up issue and 5 days later things still getting worse.

So I gave full strength nutes for only the second time in there life today.

Any ideas?

First pic day 38 you can just starting to see some of the plants starting to light green/yellow

Second pic Day 41
Third pic Day 41 good/bad plant
Fourth pic Day 47 you can see most the plants turning and the tall plant looking the worst

Looks pretty normal to me. Are you harvesting by trich color? They could go earlier than 20 days. But, I don't think it's anything to worry about much.

[manels1111]

I'm going to harvest by trich color. But 10 weeks for lowryder #2 is pretty standard. I looked at the trichs the other day and no ambers yet for sure. My last grow didn't turn yellow at all thats whats got me freaked.

Where are you at in the feeding schedule? If you stopped giving grow big and are giving them beastie bloom they will usually deplete of Nitrogen quickly.The cha ching will bring back the nitrogen.
Or if you like give em a dose of grow big.

[manels1111]

Yeah I really think its a nitrogen problem I noticed the cha ching is 9 N so I'm hoping that solves the problem. Also the N defecieny falls in line with how I nuted them. I'm not used to growing an auto flower. But I fed nothing until week 3 and the plants were already showing pistols. At that point I started with tiger bloom, big bloom, and open sesame. They never got any grow big because they were already flowering by week 3. On top of that my first nute at 1/2 strength at 3 weeks old of tiger bloom, big bloom and open sesame the tips showed a little nute burn so I watered with regular water the next two waters. Which put them about 5 weeks/28 days old with only 1 nute of 1/2 strength. Then at about 6.5 weeks I watered with full strength tiger, big bloom, and beastie. In the next few days they showed the yellowing leaves. I flushed last week and then today just gave them a full tiger, big bloom, and cha ching. So they have had very little nutes in my opinion.

I'm just hoping maybe someone with a trained eye can tell what my defiency is?

Just thought I would ad here is a picture of one of my last good ones.

Hello Man.. Believe me You will not solve any Nitrogen def from using any of the FF Bloom Boosters. Make a long story short I received 6 sets of OpenSesame,BeastieBloomz and Cha Ching... The stuff Works Ok with Mixed results on various strains but always causes extreme yellowing IMO. I only use the ChaChing after experimenting with all three for a year.. It packs on weight and trichs but its hard to control
.. I think the Open Sesame is useless..:hippy: d:rastasmoke:

I've got to second the above, I think they look pretty good.

[manels1111]

What would you suggest at this point?

1. Just chill and let them ride out the next 20 days and finish.

2. Give a little shot of grow big veg nute?

3. Other please explain



Thanks guys for the help by the way.
