ive had another post on this but its kinda dead and things are getting no better. i believe i overused ph down and locked out low end nuts. P Calcium magnesium, maybe more. i started soaking seeds on aprill first vegged till end of may been flowering about 2 weeks now.

I have flushed about a week ago. and gave them half str flower nuts after a couple days, 10 30 20, and it has basic stuff in it too the magnesium and calcium. the water i used to feed was raised to ph 7.5+ to try to raise the soil ph up. ive also fed them all once more with slightly stronger nuts and slightly higher ph. im done adjusting ph. any more and i fear i will just make it worse. some run off is still below or around 6 some is up around 7.5. so now i will just use my tap 6.3-6.5. i do let it sit out.

before flower they had 2 feedings of bat guanno tea and one of a basic veg nut 24 12 18 i think. in ff ocean forest.

i have some dolomite lime but i think i got it too late now. any ideas on what to do or not do. to correct this will be helpful and appreciated.

5/15 is about when i started noticing something was wrong. took a while to figure out what it was. the first pic was then by 5/25 it was in full attack, rusty color'd spots on leaves, lower leaves on near all plants yellowing distorting and dying. By 6/5 things are completely to shit, i think i flushed on 6/3. pics go pretty much in order from oldest to newest. as you can see its not all bad but the condition is moving up toward the healthy stuff. the last pics are today.

Could it be lack of light to lower leaves?
i have a new 600watt hps im in the proccess of hanging maybe that will help.

Ok it isn't that bad because a majority of your plants leaves are still health looking.

I would stop giving them nutes for now, and flush with Ph water of 6.3 to 6.8.

Keep flushing until the runoff reads the same ph. Flushing will stabilize the PH soil.

Once you have accomplished this, do not give them nutes yet. Just watch them.

From there you can use nutes, but remember during the flowering stage you want to give them a nute that has a high phosphorus.

Read this article and will explain fertilizers http://www.learn2grow.com/gardeningguides/fertilizer/basics/understandingfertilizernumbers.aspx

You will be ok

yeah i know about ferts, when and what and all. thanks for the vote of confidence. i suppose i could flush again, i do have to drag all the plants out tonight to install the new 600 watt hps. and yeah im done with any nuts for some time now. they will hopefully pull on around.

Hi Ery, i was checkin out your situation earlier. I think you're right about the main issue being the PH. And totally agree with what Keico said too.
If your tap water is 6.3 - 6.5 , 1st off lucky you, mines 8.4 :-( and like Keico said flush it through till it all evens out. I think they'll rebound for you. Good luck!

i suppose im in for a bit of work tonight :p

last time i flushed them was tedious at least.. and puttin up the light and cleaning up the room rightly, then maybe setting up my cfl rig in the cloning room.. i normally try not to associate growing with work, more a hobby. tonight though will be different

Yea I know what ya mean, sometimes it can feel like work, but for time invested is well worth the end result

looks like root rot to me. kinda hard to fix that late into flowering. slow down on watering for a bit.

p.s. the damage is already done. you may have solved the problem. check for any new growth, this is your best sign.

some still suffer. some seem to be on the up swing. ph on run off is still coming to a decent range some still a bit off. mostly thats the worst looking plants. i think they will pull through. here are some pics, at least the buds are looking decent for 2 weeks eh?

still i have a hand full of ded vegetation. and thats light burn on that one plant with the sativa the close up leaf is from my main problem.
