Yeah I have got all sorts mate b52, big bud, bud candy etc. etc. but I have only been using the Sensi grow/bloom A&B. Maybe l sould give them a shot next feed and see how they look.
I gave them one shot of cal mag near the start and that's all. I would be worried about giving it to them now as its 2-0-0 and I thought the extra N could be bad at this stage?
