Is it best to drop the bloom booster for all plants in general or just our type of plants?
My pH is kept around 5-6 after I add the nutrients to the water and before replacing the water in the reservoir. So it looks to be iron lockout.
Thank you for commenting.
EDIT: These people claim that it could be that the water is too cold. Which is a real possibility this time of year in South Africa.
Came in this one late but, Church got this with the nutrient "cock blocking"......Next page has the OP giving the pH at 5-6 and I would be pHing to 5.8 and letting it rise to about 6.1 - 6.2 before adjusting down again. So maybe a tick low - BUT not the pictured problem!
