The only thing could be "over-feeding": too strong and too many x's per week. A plant really need to be feed 2-3 x's per week - but being an auto you are in middle flower so consider a short "flush" (4 days) with a dry day or so after flush, then start using corrected amounts of nutrients . Use root juice till week 8 of flower. you plant has only at most 2 more month's till harvest

[george]

[steve]

[george]

To much fert. To close to light might also be ph. Check for 6.5

[george]

I did everytime i do that its , i saw a chart for the lights and u can put it till 20cm distance for 250 w hps. and if its light i need to bend?

Lower original leaves will fade out and die....

Super crop that tall one to make even and drop light....

[george]

So what shall i do i already adjust ph so is it norma on 5th week of autoflower?

[Green75]

Went back and looked at pics again...I see no nute burn signs really....our curled top leaves on tops...you might just have a ph issue....but I did see you are using both grow and bloom nutes at same time...nooo she is an auto and in flower stage so feed her bloom nutes. Might also be a nitrogen toxicity due to that...

Ph make even 6... Always
6.5 is not enough fudge room

[george]

i just followed the program of biobizz didnt know about grow, and i read that bio bizz soil need nitro for flower just a bit , is that true?

[Green75]

Sure but not that much...not as much as when in veg stage.

[george]

i just pute 2ml in 1 litre of water then in 6 7 week i will reduce it 1 ml

[Green75]

Bloom nutes only...

[george]

And one more thing i put 1,5 ltr water and doesnt ran it off at allanymore like it used to do.

[Green75]

Use more water till you get decent run off...like 20% run off....Always at 6 ph...water and nute water...6

Autos only require a fraction of the nutrients usually given to cannabis plants.
no more than 1/2 what you would normally use .
