I just went through a problem really similar. It turned out to be a Mg deficiency. Check out my thread in the Plant Problem section to compare pics. I finally got the problem under control, but the leaves that were affected by it all died off or got pruned.;)
By the way the thread title was Mg deficiency or Rust Fungi!!!
Thanks Agoblue read your thread and I'm glad to hear you solved your problem. Two reasons why I don't think it's a mg deficiency. 1) I've been using cal-mag+ since about week 4 at 10 ml/g. And yet the problem seems to be getting worse. 2) your pics look different from mine. The tips of my leaves are crispy as well as the edges. On yours I didn't notice that. I'm not saying it isn't mg deficiency just yet, I just don't understand how it could be. Also, I'm using tap water which should have enough mg in it already.
As promised, attached is a pic of the general size I try to go for when it's ready to go into flower. To be perfectly honest though this rooted clone is a BIT bigger than I would prefer, and a plant this size once finished will give easily over an ounce. In a SOG this plant will likely hog up too much space given my setup, so I'd aim for something slightly smaller. The goal is 3/4 ounce per plant. Hope that helps.Quote:

All the info you have given has been noted. Again, appreciate the info. The people on these forums are so much more helpful than that other forum...cough cough *RIU* cough :D
Gah! Today's mood is glum. I have 2 pieces of news to give today.
#1) My hydro guy just dropped a knowledge bomb on my face today. He told me "everyone knows that when dealing with these companies, whatever they tell you to feed, cut that in half!" Apparantly everyone's known this but me :wtf: he said this is especially true with Advanced Nutrients. Soooo....although I started cutting down the 3 part formula by half for a while now, I've still been using all my additives at full strength (koolbloom, hygrozyme, cal-mag+, Sweet). And get this, I've been using Koolbloom (powder) since like week 4 or 5 of flower, and I'm told using this stuff earlier than 2 weeks before flushing can cause harm :( In short - I think I've botched this grow by overfeeding, feeding improper proportions of additives, and using additives at improper times. However, I'll finish what I started and continue writing this log.
#2) There is some good news! I've been experimenting with coco, using the same strain, and she keeps my self esteem afloat while I burn the plants in the DWC :D
day: Not sure what day of flower she's in. I will guess 28-32.
Nutes: House and Garden Coco A&B @ 12 ml/g each, cal-mag+ @ 10 ml/g, hygrozyme @ 5 ml/g,
I will continue to log her along with the DWC plants. I gotta give House and Garden props for suggesting food levels that are ACCURATE, unlike those money grubbing chumps at AN and GH grr.
more pics later tonight...

Nice plants!
Are you still using tap water? Might be holding your yield back by using tap water. 200ppm is pretty high for water to use for hydro. Filtered water ranges from 6ppm - 20ppm depending on the bottling company. It would be beneficial for you and your plants to replace the unwanted ppm's with nutrient ppm's. Try it for a grow, wouldn't hurt....
If I were you I would veg longer and trim more. And what i mean by trim more is to leave like six to eight bud sites per plant when starting 12/12. You have the head room for it and the 1k watter can envelop the plants in the small space. I've done a similar grow in a 2'd x 3'w x 6'h with a 1k hps, 1 plant dwc/aero, veg 30 days, fl 60 days, yielded 3-4 oz. You can easily double or triple your yield by vegging a bit longer. Just my opinion though....
been a while.
harvest time: 77 days. A lot longer than the 8-9 weeks estimated by Serious Seeds. But then again these plants have gone through significant stress, from the beginning of flower during transplant, and throughout flowering with nutrient burn. But finished at last.
Cangroit, thanks for the compliment. I did use tap throughout the grow, and I will consider your advice for a future grow. It does make sense that the 200 ppm in the water could go to better use.

pic 2: all 8 plants with their fan leaves trimmed. Next time I'll go for more uniformity in size.
pic 3: into the drying tub they go,with the lid closed and plenty of air holes for circulation.
I'll update the final harvest weight with pictures and a smoke report in about a month when they are done. Thanks for stopping by. :pimp:
- the em
update from the coco plant.
day: 40 ish
pic 1: here she is. in all her glory.
pic 2: close up of her face
Here she is from pics taken about 10 days after the last set. February 16.
