I've been using medina hasta grow fertilizer. 6-12-6 through the veg and I'm now 2 weeks into flowering. As I understand it... would be better to lower N levels and increase the P-K? I was hoping for recommendation on a organic fertilizer for flowering. Just 2 cents... I've found the Medina fert. to give pretty good results. Only comparison is with GH 3part. I would say it was much easier and results are very similar.

small cabinet
250 mh
plenty of ventilation
pro-mix potting soil
water with left out tap. ph after medina 6.7

any high phosphorous guano.

use metanaturals bloom its all organic works great

thanks you guys I knew that the guano was high in phosphorus; do you use it dry and top dress or make tea? Thank you nozthedon kinda more what I was shotting for... a brand recommendation. Thank you both though.

Either is fine. you can also dry mix it into the soil before you plant.

Technaflora Pura Vida is also OMRI-listed and useful in hydroponics.

can i use seeweed extract when flowering

Only prob i see (with seaweed extract) during flowering is it can increase the use of N by the plant and "stretch" the plant. I definitely wouldn't use it during the last half of flowering.

I use high p Guano myself. In the last third of flowering now I'm going to make some tea from the stuff, as in five gallon bucket, RO water, bubbles (air, not the entertainment ant the last bateleur party you at) to break it up. I'm not into solids the last part of flower. (let you know how it turns out)

Solids I mix in a 'medicine bottle' with little RO, shake, and dump on the soil surface. then water (always water after solid dumps). I mix then dump, left the stuff in the bottle for a couple days once. That was a smell.

thanks mate have to put some more pictuers up later
