New Grower Help ! First grow ! is she going to make it ? (auto White Russian from serious seeds)

[calabria420]

My first time growing she's almost half way through week 6 , and is just over 15 inches tall here's some info :
-Lighting - cfl's
-medium- 50% janes organic potting soil & 50% vermiculite in 5 gallon pot
-nutes: Dutch pro grow soil a & b and ph down for adjustments to about 6.4 - 6.5 ph
-18 inch oscillating fan on low for circulation in a 12'x 6 ' washroom in the basement and a dinky humidifier to add a little humidity . The room temp is about 23-24 celcius @ about 38-44 % RH sometimes a bit more or less depending if I turn on ceing exhaust fan or not .In the canopy area it's about 27-28 celcius at about 30-35% RH .
I started her on nutes during week 3 at 1/4 strength then slightly increased up to half strenghth to this point . I never started keeping track of the ph until I started feeding her nutes at which point I bought a ph pen tester and started to regulate her water and feed .
i just did a soil test and it showed a ph of 7 just before I fed her yesterday . Her fan leaves are looking very sick and the deficiencies seem to be getting worse ! I've read all kinds of things but I'm not sure what I should do ! Is it too late to save her ? Also the last feeding I gave her was of veg nutes, I will switch over to bloom nutes next feeding and start swapping out some of the 6500 k bulbs for 2700 k . Any help and advice would be greatly appreciated ! ONE LOVE ! Here are some pics ! Hopefully I upload them right , cause it's my first time doing this !

Looks like nitrogen deff.Iwould give her a full dose of nitrogen along with bloom nutes.She also should be getting cal/mag every other watering.Remove those yellow leaves.

Thanks for your reply ! I really appreciate it ! So you are saying to add extra nitrogen to the half strength Dutch pro bloom nutes next feeding ...? And do you mean to actually physically remove the yellow fan leaves by cutting them off ? Sorry if I'm annoying with my questions I'm really a noob to this ! How much nitrogen should I add ?

First off you need to get the ph of medium down... You need to test your run off next watering, also ag this point don't add any nutes as she's ph locked out and the added nutes will just add to the trouble.... Try to just give her some plain old ph'ed water maybe say at 6 and than water till about 10% runoff and than test the run off to figure where your at... She definitely is still saveable and to medicated and too much going on to post the proper forumula of testing the run off but I'm sure someone will pipe in soon.... :karma Cloud:

Got ya covered,

[h=2]Rough Calculation Guide:[/h] Here's some good info on ph.....
If your runoff pH is higher than your starting pH, use this equation to determine your soil pH:*
Soil pH = Runoff pH + Difference

If your runoff pH is lower than your starting pH, us this equation:
Soil pH = Runoff pH - Difference.

For example, say your the starting pH of your solution before it goes in is 6.5 and the pH of your runoff is 7.0. The difference is +0.5, so using the above equation:
Soil pH = 7.0 + 0.5*
Soil pH = 7.5

If your starting pH is 6.5 and your runoff is 6.0, your difference is -0.5 and using the above equation:
Soil pH = 6.0 - 0.5
Soil pH = 5.5

I strongly suggest a good soil probe,

I agree try and get your soil ph down first,Have you been using cal/mag?What are the npk numbers of your veg nutes and bloom nutes>Yes,remove the yellowed leaves because they will not recover and are of no use.

Just looking at my Dutch pro autoflower soil chart and it advises optimal pH of 5.8. Noticed you have been using pH 6- 6.5.

 

[namvet25]

I believe that 5.8 reading is for hydro not soil.

Just checked and def on soil chart. Have only just started using these nutes myself. ????????

 

[TRIPDOG]

Just double checked on web site. Dutch pro soil pH 5.8 to 6.5. Dutch pro autoflower soil allow to drift between pH 5.5 to 6.5 (5.8 optimal). Sorry if I have confused things.
