Bleached Yellow is it PH or deficiency

Hi I have a serious problem ,

I got a G13 haze 6 weeks+ , was growing ok , until a stupidly decided to give it some organic shit Tea 2 weeks ago, seems the tea ph was very low and from there it was downhill, its still growing but all new growth is yellow , I flushed it last week with tap water ph7 run off is 6.5, but still all new growth is yellow.
Yesterday I gave it plain water ph7 with superthrive and some CalMag+.

The Soil is a German made soil with slow release fertilizer soil Ph on the bag is 5.5-6 , so maybe when I flushed all the nutes are gone.

So my Q. is …..Is it still a PH or is it a deficiency or What.
Should I take a cutting from it and start fresh..
Help…..


Grow room 2x2
Temp 25c light on 22light off
Lights 150Mh + 15 HPS
RH%50+-

Correct me if I'm wrong but correct PH LEVELS for soil is between 5.8-6.2... If your PH LEVELS are 7.0 then your most prob locking the plant up so it can not receive nutes..... You've completely flushed ? Purchase EC meter and start off by giving half dose, see how plant responds to this, if ok then add a little more nutes, you really do need to measure your EC to make sure your not over feeding etc, put some cal/mag in.

Thanks for the reply,

To my knowledge soil ph should be around 6.8 Hydro is 5.8 , I put-in water with a Ph of 7 and the runoff was 6.5
Also Im not feeding them the soil has all the stuff needed until 8weeks based on my last grow, but being a smart ass I said lets give them some Organic shit, And The shit hit the Fan for my
The last watering was yesterday I gave them some CalMag.

Hope that helps ... in solving my problem

I have never heard of PH that high for soil..... Soil with enough feed for 8 weeks never heard of either.... Are you UK or USA etc... Maybe things are a little different ..... But 8 weeks without any added nutes ?????????

That thing needs feeding get a good grow nute feed... asap!!

Edit: Could be a zinc deficiency.. So as i said try a good nute feed (but look for one with a good zinc contents)

German Miracle Grow.

flushing only releases more ferts

Ok Thanks,

I'll feed them a low dosage and see.
