I’m back for some more abuse.


Coco
600w HPS
Emerald Garden nutrients system dialed back to about 1/3 recommended usage.
Blu Mat watering system. Thanks @xtsho
Environmentals have been great this time. I got out of a tent, and into a closet.
5 Chem Dawg feminized seeds from Canna Genetics Group and 1 bag seed.

Things looking really good right now. I’m going to introduce Avalanche bud hardener next 3-4 weeks.

My biggest concern has been the big fan leaves at the bottom going yellow.

Any thoughts on what you see?

Yeah im not critiquing your grow or whatever but trying to make you a better grower (spread the knowledge). The first pic, the top left plant is starting to claw a little bit. She might not like the N youre giving her right now. I can see a few burnt tips on that one as well. The plant on the bottom right has some burnt tips as well but its yellowing up from the bottom, usually N deficiency, but theres a magnesium deficiency too. See how the veins remain green on that bottom right plant, thats Mg deficiency.
My friend your coco looks dry in the bottom right hand corner. There are many schools of thought on how to grow in coco but I follow the one to NEVER let the coco get dry. When it gets dry like that, the nutrients (if using synthetics) tend to accumulate causing salt build up and can cause nutrient lockout. Which is what I believe is happening to the bottom right plant.
Im not going to say it could be the blumats but I too was looking at getting one of those blumats set up but I saw mixed results on those things. I decided to build my own drip system to avoid what might be due to your blumats not feeding your plants. I would fix those blumats and make sure to adjust them to ALWAYS keep the coco wet. Trust me if you dont believe me look at my current posts in the scrog thread and youll see my plants.
If you have an EC meter, grab a shot glass and catch some runoff after letting the runoff pass for about 3 seconds. Test the runoff and if its WAY over what you feed (by about 300ppm) then you need to flush with about half of what you usually feed and get that in the runoff and feed a little lower than what you were feeding.
Im sorry I cannot look at your nutrient line to see the npk value, im about to do something very important.
