definitely burned...what's the solution. ak48 hydro

[Learning all the time]

so, I changed my res three days ago and the next day i started seeing some burnt tips and yellowing lower leaves. i think it was too much nitrogen. i've carefully watched the last day and a half as more and more leaves are becoming scorched and mottled. looking like calcium deficiency, but i believe it was too much nitrogen locking out the cal and mag. i pumped out half of my res and have topped with fresh RO. down to about half the PPM strength, and a ph of 5.7. I have extensive notes on the ammounts of nutrients i used and ph levels through day to day. anyone want to PM me and help me figure out a solution that is best for my situation. i can post no pictures, but will exchange privately. thanks for your help.

these are some pics since the beginning of grow and the close up of my nute problem. please excuse the magnetic interference and the fact that they're iphone pics.

I'm still trying to figure out the attachment thing. my bad.

You should also buy a camera cuz cell phones take shitty pics.

i realize the color and magnetic interference is pretty messed up. my lights turn off in an hour and i'll move from my iMac to my laptop and have pics under CFL. hope you can still help.

Im not being a dink but surely you understand it is tough to help without being able to see the plant.

 

[Learning all the time]

let me know now what you want to see...like i said i have a bunch of notes for what i've fed them and ph and ppm levels more than once daily.

 

[wannaquickee]

without pics id would say (calmag) if there are purple/red spots starting to occur. if not..ph lvl you say theyre fine butttt................................
also just take off feeding for a week. straight water..change res everyday for the first 3 days after 7 days go back to nutes

 

[wannaquickee]

oh and also you dont need RO water for hydro. tap water is fine

last week they were perfectly healthy. they were on an increasing schedule of all advanced nutes with cal mag from botanicare for sup and sweet for taste.

In a 40 gal res R/O water at 10ppm:
cal mag to 317
AN grow to 552
AN micro to 737
AN bloom to 878
Rhino skin
bud candy
bud factor x to 884
bud ignitor to 900
big bud to 935
sweet to 1030
hygrozyme to 1040
sm-90

this week, i went

cal mag to 312
micro to 841
grow to 1140
bloom to 1340
rhinoskin
bud candy
bud factor x to 1345
b-52 to 1430
big bud to 1500
hygrozyme
sm-90

i think i hit them with way too much nitrogen, and that locked out the cal and mag, i tried to compensate by putting some hammerhead in and pumping out half my res refilling it with r/o water and ph'n to 5.7 the ppm is now at 945. should I completely flush the res? or was cutting everything back good enuf?

tap water may be fine in your area but southern nevada is a different story. get RO or else!

fresh pics in half an hour...


...and don't call me shirley! haha

 

[Learning all the time]

maybe anyone using an advanced nutes lineup can tell me wether or not i should bother using cal mag at all. cuz it might be too much calcium. I am using R/O water and have heard i must at some point due to the lack of things in said water. please, anyone, help!

So these are the same plants under cfl after my lights turned off. again, cell phone pics but best i can do this quickly.

that's a good representation of the coloration and area of the plant at which its happening. I have had nothing but green leaves until 3 days ago. day after res change with previously mentioned nutrient regimen. any insight will be apreciated. please read my previous information before asking a bunch of questions that were already answered. nevertheless i will try to answer everyones questions that are able to help. thanks in advance.

Looks like a Ph problem and also possible lock ouy.

 

[Learning all the time]

the ph has not left the 5.5 to 6.1 range since they were clones. sound right?

lock out: What do you think I should do? Run 40 gal R/O water through it asap and then start with fresh nutes? what do you suggest? anyone?

 

[rastadred22]

id say flush slowly goin bac to normal schedule...wats the point of the screen? it doesnt seem practical as they are not being used
