chem burn or missing something ?

comments

Kind of looks like nute burn. Does the whole plant look like that or just a few leaves on top ? What are the white spots ? infestation ? Can you show the whole plant ?

Nitrogen (N) deficiency is what you are showing. Could go into toxic salts too so watch the other plants. N is the one thing that locks out most of the time too. You can try to change the nutrients and give enhanced N or you can flush the whole medium for a few days then go back to a full NPK. You can also treat with a dose of N as well like seabird guano, fish emulsion and blood meal or use an enhancer that has an extra dose of N.

If it is a lock and you add more nuts.. you could be in big trouble... I would at least flush for 12 hours... straight water... zero ppm and 7.0 ph.

lets us know what happens

: )

flushing with ph 5.9 water
switching too GH 3 part liquid
28 days into 12/12
any hints on mix. ?
these are the trees in the other posts .
to be safe flush for 48 hours ?
What causes N block ?
epsond salt make root look white,
why every outher time , could be the problem ? what do u thinks cause it ?

deficiency is not always lockout, most of the time it's just the plant needs more (N) then the others and that's all.

There is a cycle feeding chart in the FAQ for GH 3-part nutrients.

Flushing is normal in Hydro for 48-72 hours keeping the Ph balanced.

I never said it was locked out. But miss balanced Ph is the cause most of the time. There is a Ph chart in the FAQ you should have a copy of on your desktop.

You don't need epson salt all the time, I use more H²o² then epson salt 5ml per gallon with every water change for vegetation and flower up to the last 3 weeks of flower then I don't bother.

thanks
