So i decided to do a couple little autos... and well one has been nothing but aggro from the off and the other seemed to be doing well but is now showing signs of defiencies. But im not sure what. The leaves are clawing (tips turning down) so i thought it may be n-tox... but today ive noticed the leaves yellowing, this is on several leaves at both bottom and top of the plant. The yellowing looks similar to nitrogen deficiency. Im confused does it have too much or too little?? Any help would be appreciated. Thankyou in advanceView attachment 3743711

Hi thanx for your response. Ive had someone say nitrogen, i was thinking maybe zinc? But ill look into that thanx

Zinc being a micro element and immobile tends to show on very new growth first . magnesium is mobile and will be shifted from older growth easily . Nitrogen normally creates a leaf that's fully yellowing not just between the veins.

Definately looks like magnesium, the solution here isn't a cal/mag solution since you already appear to have some excess nitrogen issues. I would feed with 1 gram pure Epsom salts in a gallon of water next feed.

Make sure you use pure Epsom salts (100% pure magnesium sulfate) don't get the perfumed junk or anything.

You need to address why you have this issue as well, make sure your feed program contains enough calcium and magnesium and that your pH is in the proper boundary.

Thanx for the heads up. While you're about can i pic your brain on my other auto?. Its been problematic from seedling, its now budding but looks under developed. Is it worth continuing with? 20160727_160225.jpg

Ive been using vitalink hydro bloom a + b and a little big bud too. I have another plant thats not auto thats thriving using same nutes. Think ill just stay away from autos i never seem to have much luck with them.

Show me a picture of the overall plant under clear lighting so I can get a look at the generally coloring/ condition of the plant.

Also tell me what it's growing in and what you are feeding it.

ph range should be around 5.8-6.2 in hydro, strictly speaking 5,5-6.5 but varying between 5.8-6.2 should allow all nutrients to be absorbed.

i thanx for the response. The testing kit im using at the moment isnt specific with the actual ph its just by a colour chart. Think i need to invest in a more accurate test means.
