Leaves darken along the veins

[ElBado]

Hi all.

Want to ask you about some advice.

My bush is having problems with leaves. They began to darken along the veins. One of the options I'm considering is overflowing the plant, although in my opinion I don't pour a lot. this is only the second try of my groving so I could be wrong in diagnosing the problem.

Living conditions:

type: Mimosa Cake Auto
substrate: peat universal ph 5.5-6.5 is indicated on the package
light: 18/6
ventilation: 150 m3/cub per hour (through coal with appropriate throughputs) Box volume - 0.25 m3
Lamp: LED GrowBoard 60W
watering: 1 liter per week (settled PH ~ 6.0 - 6.5) + fertilizer start from the 3rd week
fertilizers:
1. Flora Series Micro (5-0-1) - 1.3 ml per liter
2. Flora Series Gro (3-1-6) - 1.3 ml per liter
3. Flora Series Bloom (0-5-4) - 1.3 ml per liter

Give her A little Espon Salt, should do the trick. jmo

I agree with George. Lookes like the start of an magnesium deficiency.

1: buy epsom salt 1ts/l and spray it on.
2: Add calmag to your water.

Do you have any idea of the EC/ppm of your tap water? (if you use tap water that is) Soft/hard?

How do U think, should is need to flush with clean, pH’d water before adding? that question because I read about magnesium deficiency/ They told that it could be blocked and not assimilated in case of not correct PH in pot. And I'm not sure for now that it correct. Thank U

Unfortunately about EC/ppm really havn't no idea. So i will try to find how to test it and ask the question again when I get the data, or at least an approximate understanding of softness or hardness. ThanK U !

Are you in Soil or Coco?

If the PH in the rootzone is 2 low the magnesium will get blocked out. I hardly think thats the case here.



Try and find out if your tap is soft of not. Should be listed at your water supplyer.

Unfortunately not in my country)

For now will try to check PH level in soil. And then add some Magnesium.

Thank U for advices

Perhaps try adding some beneficial bacteria and fungus like mykos or ecothrive biosys, that might help make nutrients more available and help buffer ph too.
