So my girls are now in week one of flower, I gave them a mini flush the other day in the form of one watering with plain RO, I then proceeded to not water for 3 days due to a lack of water (a mistake in coco I know) anyway now they are showing signs of slight yellowing leaves  red stems. I have gone back to regular feeding at about 1.7 ec but am worried it will affect flower development as they are now on 12/12

Looks like either a magnesium deficiency or a copper deficiency.  Cal Mag and Micro should help. Coco makes plants starve a lot for magnesium. I always mix Micro in with my Cal mag and water mix with nothing else on my water only days.

Actually, when I grow with coco, I try to water once daily. Day one is the NPK (Grow and Bloom). Day two is the Cal Mag and Micro. Day three is Silicates (Sturdy Stalk). Then repeat. Leaves don't usually recover so I always try to look at the new growth.

@southwestsmoker The farther you go along in flower the less you should use. Cal Mag and Micro can build up. These two are high in Nitrogen. To avoid getting Nitrogen toxicity, it is a good idea to start using Mag Sulfur here in a few weeks. Your leaves don't look very dark green so some extra Nitrogen won't hurt them.

Magnesium and Sulfur is found in Epsom Salt. You're in the early stages of flower so if Cal Mag is all you got for now they should be fine.

oooof, unlucky mate! When the medium dries out the EC rises and you get an EC spike, this could be causing the issue

I agree with this, its about the right time too. Coco grows will usually get a mag def on the first week of flower after a long veg. Spray with some epsom salts mate and they will be fine Smile

about half a teaspoon of epsom salts into 1L of water and then spray the leaves, top and bottom with a fine mister spray. They will feel much better after that Smile
