Hello guys im new here.. I have one litle problem with my babies...first of all i grow on an open hydroponic system made by me.I use flora series from general hydroponics.Now my plants are 2,5 weeks old.I use ph controller so i dont have ph problems..My ph was at first at 5,9 but now i put it at 6.1 cause i though maybe the yellow lower leaves and the pins was from some defiency.Here some photos ...now im giving them 2,5-2,5-2,5 since the start and now i ll give them 7-7-7 ml as the bottle plan... 2x augan auto and 2x chocolate skunk auto( note flora series have full N cause they have Nitrogen to the micro-nuts too) ty for the help... Sorry for my english!

i would give them more veg nutes and some cal +mag. if you dont have that use molasses black strap.

Flora grow has 0,5% magnesium and micro has 5% calsium.I raised the ph for better absorption you think i need more ? Or if i raise the nutrients its ok?

ti think 6.1 is good. i see you got feed tubes. so in your res what is your ppm?

DCobeen · Mar 20, 2014

That is the cheapest way. i bought that one and love it. id has a flashing 10x symbol which is hard to see till you know to look for it. besides that i love it.

Lacking Magnesium. Notice how the veins remain green while the margins are yellowing starting at the tips and moving inward? The veins would be yellowing along with the margins if it where a Nitrogen deficient. I would add a 1/4 tsp of Epsoms salt per gallon o your res for a start.

Ty for help.. but the water here in my place has a lot of salts...epsom are different?
