hey all,

First grow back in a couple years, dipped into coco for a run and I’m having my go with it.

I’ve been slightly under feeding because I saw a sign of slight leaf curl.

I tested my run off and it’s at 6.2 with 650ppm

I’m in week 2 of flower and I’m thinking they have P/K deficiency with a PH unbalance

I’ve been watering at 5.8-5.9 every time - last feeding had 700ppm

Any help is much appreciated!

Didn’t kill the lights will update tomorrow if it persists, hoping the last watering helped.

Only time will tell.

Hard to see any coloration with the lights. Sorry.

Here’s some updated photos for everyone

The last photo shows a slightly better plant that hasn’t seem to get N deficient

*edit* the plants look olive in color, total lack of vigor, could it be PH lock out?

Happy Growing

Hmm. I would increase my calcium supplement. What are you using for a nutrient mix?
Are you testing your run off daily to monitor your feeding? I don't grow this way but ive considered it. I like to keep my hydro dialed into exactly how much the plants are feeding. A ppm of 700 doesn't mean much to me if I don't know what the last 2 days were.

Just calibrated my Hanna meter. Shoulda gone with what I knew....hit em with 800ppm a little extra N and Macros. Heading outa town on Friday after work. Finger crossed I don’t have to scrap a grow for the first time ever. Many a year history lol

My last two days were 650 and 645 always ph at 5.8
 
Harley is right about a bit of heat curl but its slight. What's your humidity? Light distance and type? They look good to me other than that.
If your having P,K issues its going to show down low first IIRC. The tips will burn and the lower leaves will die off.
 
Looking a little better tonight, too bad I’m heading out of town and I can’t pamper them like they deserve. Fingers crossed one more watering to get in before work tomorrow at8am. I’ll post photos tomorrow

Happy growing
 
Here’s some updated photos,

Problems persist slightly, looking a little better but still slightly N deficient it seems. Got home and fed with 1100ppm ph 5.8

Thoughts?

Could be root disease issues. I would folar fed regularly until you determine. When SWIM finds leaves shriveling up and looking prune like, the plant is not transporating and taking in water properly. I would folar feed and try to determine if there are root issues before it's too late

Those are nowhere even remotely close to scrapable....I see very, very minor leaf discoloration. Granted that can be a sign of future issues yet to develop, but I don't see anything that would make me lose my noodle...
Stay the course.
