I prefer to have total control on what I put in, a true dictator lol. I only use preloaded if need to, all I have. If I do I use a mix of HF/OF/Coco loco at 40/30/30. I like Happy Frog more not as "hot". I only have run auto as of today so cant speak on photo schedule. I would not run them in the same room, I would pick auto or photo but that's me.Appreciate your info., I’m going to switch to 20/4 next grow like u & see if my avg stays the same...running photos & autos current grow (switched lighting to 13/11 @ photo day 15 & autos were day 26 & already flowering by design timing. All doing great , autos flowering the same as 24/0 previously & 2 photos pre-flowering in 7 days surprisingly-4 others are not.
(I use Happy Frog Ocean Forest & Miracle Grow seed starter- quite honestly live the MG seed starter not lost a bean yet). Feed with Orchid Food Nuits (high P-K) & Molasses now, switch to P-K later after week 6.
Some articles I’ve read mention feeding larger amounts of P-K early to promote faster flowering as long as u are using “hot soil”, which Ocean Forest is...comments welcomed pos or neg !!!
