At the very begging of my troubles i thought iron def may be the problem until all different things started to happen and i sorta forgot about the iron !! Any way, i have 6 plants in different stages of growth and have bought a powder (just containing iron) that i have mixed up at half strength to play it safe. I have watered all plants (just now) and also given a foliar feed which i intend to do every day for a few days. My question is did you have to continue adding to keep the iron to the feed for the rest of the grow or just occasionally or not at ?
The box says that it lasts 2 or 3 months with the one dosage. I am growing in BioBizz light mix and intend to grow in coco the next time around as i believe this will be better for nutrient take up. Many thanks for this thread and any words of wisdom that you have learnt since writing this thread. :thumbsup:
How did you make out Mr gold after adding the iron? I am having the same issue with 500UV's...lime green on new growth. This started almost instantly...3rd day in.
