is it going to die

[dizzy spells]

ok heres the problem.
i have 1 plant growing in a greenhouse in the garden (uk).
growing in coco husk & fed with hydro tops grow solution a & b. 4ml to 1 ltr water.
the plant is about 4ft tall & was looking nice & green.but now the leaves are starting to go a lighter shade of green & the leaf stems are turning in color to purple.just on some of the leafs,not all.but the leafs look like they are dying off.is this normal for this to happen on a outside plant.
i have flushed out the roots & changed the feed to ,hydro tops bloom solution a & b.4ml to 1 ltr water.
now the plant is in bloom,should i increase the feed or am i wasting my time with it,
any help appreciated.

my guess would be a MAG deficiency... try adding some dolomite lime... Check the PH of the soil if you can... could be a nute lockout. My plant did that exact same thing and I added lime as a top dressing and pushed some water down.... Lime has calcium and Magnesium and will act as a PH buffer to not get a nute lockout... You still have to keep an eye on the soild PH though.. Hope this helps

im finding it hard to get some dolomite lime but been told that epson salts do the same job. magnesium defiency.spray the leaves.im going to get some tomorrow.
how long before i can see the effects?.
or should i just get the dolomite lime?
shes still getting lighter in color.

dolomite lime will stablize your ph-6.5-7 and it adds mag.the lime will make a huge difference in your grow.epsom salts are great if you need a qiuck shot of mag.definatly get the lime.2 tablespoons per gallon of soil just top dress it wioth the lime

also put the lime on the top of the coco husk & poured some feed on to dilute it to the roots.
