Hellooo!
My Jack Herer auto isnt 100% happy. Early on i had some suspected nute burn so i dropped the ppm way down and ive been bumping it up since then, about 100 a day. But the tips are looking a bit burned to me. I dont know how she can be guzzling nutes but then showing signs of over feeding?
Or is it maybe a deficiency in which case i should crank the ppm up even more?
Any ideas?
Cheers!

Haha sorry!
PPM 1030 down from 1200 24hrs ago, pH 6.3. Thinking about it pH has always been 6 - 6.5, its going up...maybe drop it and let it rise from say 5.7..? Its hardly been below 6...
Cheers!

Yeah,higher ph locks out others so it can burn tips you get an imbalance .1000 ppm is also very high thats 2EC on .5 scale. My self I stick to 1 EC so 500 ppm.Its easier to grow with a slight deficiency in hydro over a toxicity.

Ok thanks i put her down to 5.6 and ill let her drift up, as you say probably stuff (dont know what!) that isnt getting absorbed if shes constantly above 6. I'll bring PPM down too thats also too high.
Cheers!
