CannaKropsstarted grow question 5y ago
First time Coco coir. I neglected to check the pH before planting, and I can't seem to get the pH down from 7 to 6. I have tried rinsing with several gallons of 5.5 pH, no help. What is safe to add while growing? Thanks!

With my experience with coco the runoff is never in the absolute correct zone. If your seeing high just keep feed/waterings at 5.5 for your veg cycle. Cheers

Done that myself occasionally. I kept flushing it with ph 5.5 and it took a while to get run off right. I check run off by collecting 15% and ignoring it or and then collect 5% and check that. I find that way I get a better idea of what the soil is. 1st lot of run off will have a different ph then the last bit.

Unknown rust on 7th flowering weekThis started as what I thought was a cal/mag deficiency, bought some, gave it for a week at a good dose and 6.3ph, and this intensified and switched from just lower leaves to the upper and a few sugar leaves on one plant. Any ideas? May calmag takes awhile? Or wrong diagnosis?

Deficiency or light stress?I start by saying that the light was not close enough to cause stress imo.. was about (30cm) of distance from this plant. it seems that it is more a deficiency in my opinion but I don't know exactly which one.. What do you think about that?

Drainage issueI'm not quite sure why this cup doesn't absorb its waterings when the other two solo cups are getting Watered every day. All 3 cups have no drainage. They are all grown in the same conditions.
My first instinct is lack of drainage, do I need to make some holes, bottom or side?

Runoffs are significantly below inputs-Do I have a problem?Runoff continues to be a mystery. When watering I continue to get significantly less Ph and PPM (4.8 ph and 109 ppm) than my inputs (6.2 ph and 155 ppm) but the plant looks healthy. I have no idea what is going on or if its even a problem. Should I be worried and what can I do?
