Magnesion def.?

[Guest]

I agree with Verite on that, the intervenal chlorosis points to an iron deficiency, plus the plant looks overwatered and like it got too much nitrogen. If your pH is out of whack you need to fix that otherwise your plant will have a hard time for sure.

looks like mag def... the viens are still green while in between is yellow classic mag def

blackfin, you've confused the iron deficiency with the mag deficiency. With a mag deficiency the leaves will pale evenly, with an iron deficiency you'll get intervenal chlorosis :wink:

if your using Reverse Osmosis water, that water has been known to be "soft", lackin in minerals... so you'd have to admend with Cal-Mag (calcium and magnesisum, and some iron/micronutes if you got that... <--- buy some liquid seaweed, the blue bottle by maxicrop has iron added + plus all the trace/micronutes)-- be careful though... maxicrop is heavily acidic, i usually half what the bottle says.

peace,

bartender, excellent advice. I personally use a 50/50 mix of tap water and RO water, it has the side benefit of getting my pH to just right without having to add pH down...but that of course depends on the tap water from the source.

I ve had to mix my crap tap(300ppm) & distilled or rain water for years. I use a rain barrel & man i love the spring & summer in the mtns. . My rain is perfect 'as is' at low 6s' on the ph & less than 15 ppm total disolved solids. It is rather bare & like bartender sugg. i also add a bit of cal/mag & EJ microblast(very little) when the plants are young until they can build a bit of reserve. Nice weed-kned to all 3ld
