Deficiency or Nute burn?

Hello!

The following pics were taken at repotting repotting the ladies:




















They are clones from 3 mothers of Wonder Woman. I think these pictures already show some starting deficiencies, but 2 days after repot things got critical. Here are the pics.



This fella doesn't seem to care about anything. Not any sign of any deficiency or burn. Same everything ofcourse.


Soil is some all purpose soil, the picture is in the attached thumbnails section. I cannot delete, so it stays there. It says at least: 0,3% N, 0,1% P2O5, 0,3% K2O. It is 50-50% mixed with perlite, it resulted in a very light mix. I cannot measure PH as of now, my device is broken. I use rainwater, so i guess that should be OK. I also use 1/4 of the recommened strength of Advanced hydroponics Grow, Micro and Bloom with every watering.

Any info is highly apperciated, I dont want to loose them girls. They are 5 weeks since rooting from cuttings, under 400W Philips Retrowhite, 20/4 schedule.

If you are feeding you definately need to read your PH and adjust it. I am almost willing to bet you are locking nutrients out with either to high or to low ph. I am going to assume your PH is very low and acidic because of the nutrients. Since you are feeding the whole lineup you should not be deficient.

Well, if its lockout, it has to be N lockout, doesn't it? It means, soil PH has to be under 6.0 or above 7.0 according to my nute lockout chart. I try to get a new PH meter ASAP. Thank you for the input!

couple leaves got tiny bit of burn on them on the tips. but you got different deficiencys going on get the ph meter then let us know what that is at. check your runoff[h=2][/h]

Here is a chart that works wonders:View attachment 2332447


First thing first though fix that PH and Im sure the problems will slowly work out.

Yep, i got that chart already, thank you. From that I concluded the N deficiency. Only after i got this problem did I realize how small scale the soil PH has from 6 to 7 for optimal nutrient uptake. Hopefully they can be saved. I need at least 2 days more to acquire a new PH meter.

I finally got my new PH meter. Results were really disappointing. After flushing with PH 6.3 water, my runoff was PH 7.5. So I flushed them all good, waiting for them to stabilize. Also I plan to use Superthrive on them when they are ready for nutes again. What would be the next step to bring down that soil PH to an acceptable level?

Any further input is appreciated.

re-pot into buffered soil or add elemental sulfur to this soil

I checked all factors that can cause the high PH. I found out, the molasses do it. They pull PH from 6.5 to 8.5!!!!! So i flushed them ladies, and hope for the best. Now that i have my new PH meter it will be much easier. BTW, is that normal that molasses behave like that?

Bump. Anyoney noticed that molasses rise PH that much? Is it normal???
