Health of plant , like anything older it gets its immunity to defenses decrease . Look into regalia as a SAR boost and for spores of many molds i cluding pm and budrot I would suggest looking into southern ag biological fungicide. mixing those together and applying them will give u 2 modes of defense and can be used till day of harvest . the mode of aid for regalia is a systematic SAR/immunity gain and overall health improvement/aid. SABF works as a surface defense where anywhere u spray it the species of bacteria will defend. the regalia can be mixed together but the regalia even if rains only needs to be applied every 7 days vs SABF I would suggest re-applying if u get rain if outdoors ( ur not )
regalia @30ml per gallon (once a week) mixed with + SABF at 5-15ml per gallon, 5ml dose - preventive , 15ml = infective/more vulnerable time of cycle.
doing this preventive actions like for pest has not only eliminated pm and reduced bud rot to a crazy % as a farmer vouch for this 100%, I’ve tried god know products for budrot and pm and none ever worked this and this safe.
even for future, these tools I use from start-finish/last week of bloom . prevention and making plant happiest is best IPM tool!

As a hint for cost ^ non cg label of this is cheaper aka cannabis . u can get their 2.5 gallon for almost same price as their 1 gal of cg and it’s same % and only diff is making it cannabis approved label. just saying I would hate to pay 130+ for a gal vs 150-200 for 2.5 gal and same thing. Just saying and u can always buy the quart of cg first than if j like buy the cheaper version
SABF is cheap, effective, safe and like regalia can be mixed with anything that allows bacteria . Amazon sells it

‘your right about the airflow thou, yes vpd is key but u need that airflow inside ur canopy but also newr medium for IPM and to let the medium dry out and breath. It’s a great IPM tool for flys/fungus gnats since they are flying to ur medium to hatch their babies.
