Aphids issues

[Mrkline006]

so you switched meters?

1.0ec = 500ppm @.5 scale & 700ppm .7 scale

so if your meter reads in .7 scale and your feeding @700ppm then you are actually feeding @500ppm.

5 gallons is a shitload of coco for those plants, espescially if you arent letting the pot dry out. im growing 1/3lb plants in 2 gallons of coco and they dry the pot out every 36 hours.

if you gently uncover some of the coco to take a peek at the roots & they arent pearly white then you have root issues, more than likely from overwatering.

maybe someone else will come along with a simple solution i havent thought of.

Im not letting them get fully dry.. i was just saying last grow the medium was COMPLETELY dry in under 24hours last run so this run is throwing me off... As for the roots, like i said just 1.5 weeks ago (almsot 2) they took a transplant into new coco (went back to the EXACT type i had last run) and roots where HUGE and white as SNOW... SUPER bright no issues whatso ever. just not use to watering when medium still looks damp?
