So just give plain water until they start to fade a little, then start to feed them.

If the leaves start to stripe yellow before that (they may well do or about the same time)......

......then they need some Magnesium.

Cheapest Magnesium within easy reach is a tub of Epsom Salts sold by any Boots chemist in the country.

About £1.25 a tub.
A heaped teaspoon per 10L until the new growth doesn't stripe will do it.

Can't use the PH liquids without it as you can't test the water.

PH needs to be bang on from the beginning otherwise Mag defs show up fast.

Purple rhubarb stems are the magic indicator of low PH, if your stems are purple or rhubarb striped then your PH is way too low.

Mag defs can still show up in veg even if your PH is bang on as Ganja is a Mag whore, she loves it and needs quite a bit..
