Convex leafs?

[supafly]

Ok guys its a small problem but its nice to get them early. I cant seem to find anything just like it in the plant abuse pages. I was told in this post that it may be getting to much N. I can't seem to find any pics just like this so I was hoping to get alittle more info on this problem and just what to do about it.

Assorted bag seed.
2 Weeks into flower
FFOF soil with D lime, Epsoms plus, and perilight
Watered with PH adjused water. 6.3 ish + or - a tenth.
Old age bloom 5-10-5 1/2 strength once a week.
Humidity arownd 60%
75 to 80 degrees lights on
65 to 70 lights off
1000 watts HPS about 24-28 inches away.

A few leafs on 2 of the plants have a convex face. Only on a few leafs per plant but enough to rise an eyebrow. The only plan of actiont that i can think of is to flush the plants. This is my first organic grow and i was hoping that there was another option that wont thow the plants way off the others. There is also a pic of the whole room so you can see that its just these two that have gotten the same treatment as the rest.

Any ideas?

Thanks

Feed your plants slightly less; the leaf curl is caused by their getting too much nitrogen. The feed you are giving them seems a bit high in P and low in K by the way.

Thanks.

Anyone want to post up some good blooming ferts that have all the nessasary parts? I have never really seen a good all arownd flowering fert.

I have used neptunes harvest, "Rocket fuel"= high P bat Crap+ super phosphate, There are lots of fert just for canna...

5-5-10 is a better ratio. I have been using a tomato feed that has plenty of micronutrients and extra super phosphate, potash and epsom salts. To save hassle in future I shall buy some cannabis feed instead. Canna Terra seems like a good choice.

Anybody have any ideas.

Here is a couple things to check. What is the soil ph? Directions for testing are below in my signature. What type of nitrogen are you using? Ammonia or urea nitrogen in large quantitys can be toxic. Plants prefer nitrate nitrogen.

Tested the soil run off last night of the few plants that where affected. The two that where the worst where pretty far off one another. One at 5.5 and one at 6.9.

Sence they had never been flushed i went ahead and flushed all of them with ajusted water at 6.3 to remove any salts and or N build up, also to help levle off the PH. I toped them off with a feeding of blooming ferts.

As far as the kind of N im not really sure. As stated in the thread im using Old Age Bloom for flower. The packaging said nothing about the type of N.

Any thoughts? Im all ears.


Thanks
