So currently I'm growing 2 Bruce Banner (fast), 2 Purple Punch, and 1 Dutch Treat. All 5 plants are on week 4 of flower and showing signs of nutrient/PH problems. I'm using fox farms oceanic forest soil in 3.5 gallon pots, perlite at the bottom, 40% perlite through out the medium, and topdressed with earthworm castings. I'm using mycorrhizae on the roots, FF Nutrients (big bloom at full dose everyother day, and tiger bloom at half dose the days i don't feed big bloom) along with Terpinator, calmag (mostly in veg), and liquid sea weed (mostly in veg).
I'm currently seeing bottom leaf growth slowly start to become yellow and die off/fall off as it becomes brown, starting as soon as week 1 of flower hit. its a decent amount and almost making a hallow dome of no leaves in the bottom middle of the bruce banners and a little less on the purple punch. There is also top leaf yellowing (only one cola on a purple punch), which im not as concerned about due to age. One plant is also having minor curling up on the top fan leaves on one main cola (purple punch).
My main question is should i flush with just PH downed water at 7.0 (soil is still acidic, with run off being 6.0 PH with 6.5 PH feedings, 7.0 feedings go down to 6.5-6.2 at run off). should i flush with 3 gallons of 7.0 PHed water per plant? I also have sledgehammer for flushing but worried about using it due to its potency on the soil. Any suggestions on preventing further plant death would be great. I'm sure its nutrient lock out
(sorry im new to this forum and tried to explain my problems as best as i could)
Edit: forgot to mention i also use bembe and microbe at every other watering at half dose to help feed it along the way through out the flowering period. Was thinking about using Clearx at the finale stages of flowering for a good flush as close to harvest as possible (want to make the most out of my terpinator seeing how ive gotten dense consistent frost across all nugs so early on) i also plan to use silica blast to help with the heat issues due to closet cooling restrictions ( 400 cfm exhaust across 2 carbon air filters and inline ducting fans, and one 200cfm intake.
