Deficiency Identification Assistance

[habitual felon]

Hi Guys,
I started growing on a whim. Just ordered some seeds one night and started researching while I awaited their arrival. So my set up is amateur and lacking, but please reserve judgment.
I am having some sort of deficiency prob. My first grow. EAST Coast. No grow journal as I work 2 jobs and just don't have the time or the funds to invest into an elaborate grow or document it extensively. But here's what I am currently working on-
2 fast 2 vast Auto from TSSC- day 1 = 07/12/2015
OG Kush Auto from TSSC - day 1 = 07/12/2015
Im using general hydro flora series at 25%. Currently feeding the bloom schedule as the girls have pistils now. Also using cal mag + 3 ml per gallon. My water is PH to 6.5 my runoff is just under 7. Im using 8 X 23 CFL 5,000. Was using 10 but my temps went a lil high for the ventilation I have. Im growing in MG all organic soil no perlite. But pretty substantial sized mulch in the soil provides adequate draining. IDK if I am leaving any thing out here. The pics are all of the 2 fast which is the sick plant except for the last pic. Which is the OG for a reference as they are on the same nutes and feeding schedule. Typically phd RO water w cal mag then 3 days dry then a feeding and 3 days dry. Let me know what all of you experts think. I believe this to be nitogen and am treating for that currently w emulsion. Back into the shadows I go. Thanks Guys

Howdy, hf
Thank you for providing some substantial info in the first post! lol
To my eyes, it looks like a couple possibilities. First, at the age of these plants, I think 25% GH is low- they look like they're hungry. The second thing is, as the plants get bigger, I recommend feeding/watering more often, perhaps every 2nd day, as the roots are taking up more as they are bigger, and you may be getting dry spots in your soil/medium that is affecting the nute intake.
Another thing to consider.. I'd mix the calmag+ in WITH the nute mix, and feed with both nutes and calmag at the same time. If you think about it, you're only feeding nutes every 6 days, and at 25%, too. I think they'll be much happier getting a feed more often, and at a higher dose now that they're growing up I'd up the nute strength to 50% at this point, and they should respond quickly.
Let us know how it goes
tokes to you

It looks like N to me. I myself would go a little lower on you Ph in to make your runoff come out at 6.5 that might let the plant take up more N without having to add more. If you're putting water in at 6.5 and its coming out at 7 the soil is probly around 7.5

Thanks for the quick feed back Guys. I will implement both of these strategies and update soon w any further signs of stress or recovery. Thanks again.

Hi felon.. I keep this on my desktop ill share it with ya!!

HF -- .... That MG soil has some built-in fert's, which can be a source of prob's with some auto's,... even so, I'm with Waxi' a feed conc. increase is called for, ditto for the Ca-Mg,.... the leaves: yellow with green veins, down low, is very likely Mg defc.; I think I see some reddish discoloring here and there, and the withered leaves, looks like P defc.,.... Symptoms are oddly severe on few leaves, while others look fine,... could be the MG soil doing weird things! Try upping the nute's, and give it a few days to show, meantime watch for worsening symptoms, or halting,.....

OK. Quick update no pics. I increased the amount of nutes to 50 % and CAL MAG + is up to five ML per gallon of both water and nutes. The deficiency has stopped spreading but most of the damaged leaves were lost. Plant seems to be pretty healthy otherwise. Pics when there is time. I think this issue is resolved thx to all of the great feedback. Back into the shadows.

 

[Waira]

...yeah, past a certain point, the plant will tap out those leaves and simply ditch them,... halting of progression is a great sign!

 

[habitual felon]

Plant has fully recovered. Thanks for all of the help!!!!
