When to switch nutrients for flowering auto

High Steve, You swich nutes when you see your plants first signs of flowering. Happy Growing! 😋

I don't grow in hydro but I think the "when" on nutes for them is pretty standard... I actually start my girls off with bloom nutes along with their grow nutes but in general, you want to start bloom nutes as they go into pre-flower. In pre-flower, I start cutting back my grow nutes and pumping up my bloom nutes (my grow nutes are heavy on nitrogen which is a detriment to the flowering stage). Good luck!

As soon as you see the final shoot been pushed up. There'll usually be a node behind it thats when you know its about to flip. Yours is nearing the stage of flipping I think. Bit hard to see. But thats when. Change water, let it sit, some ppl use flora kleen. But if you are using a grow and bloom ratio then just change it to bloom no need to let it sit for a few or use flora kleen. Good luck
