Hi all. First time indoor/coco grower so entirely open to advice and mentoring.
Strain: Wedding Cake AutoFem
Medium: Coco Coir
I have a 4x2x6 tent, SF2000 LED light, humidifier, 3x oscillating fans, one inline intake with filter and one inline outtake going as well as 2x sensors for temp/humidity (one upper and one lower).
Im on the start of week 3 (Day 21) and notice some stress but not entirely if its nutrient deficiencies like nitrogen or phosphorous, or possibly just phototoxicity from the lights (have them at 30 inches above at 50%) and the slight burnt tip led me to that idea but it was also sitting on the coco early on and may have been nutrient burnt possibly?
Im going to transplant this weekend to a 6gal fabric pot in coco/perlite and maybe some worm castings (thought about doing some happy frog mix in it but not to sure on that viability).
I currently use Cronk Nutrients (bonnie, kelp me kelp you, cal mag and monkey juice.
I do pH my feeding water to 5.8-6.5 after mixing nutrients or just plain water.
Humidity levels tend to stay around 65-75%, temperatures fluctuate unfortunately since my setup is in my garage and doesnt have desginated AC. I do my best to keep in the 80s but with the recent heat waves its been in the low/mid 90s.
Any help on identifying or advising would be greatly appreciated.
I would higly recommend trasfering her into a fabric pot. That metal is going to absorbe heat which will transfer to your roots.
Secondly, she looks hungry. I would recommend next watering to water until run off and collect a sample to run a PH and TDS test and adjust feeding accordingly.
That’s your issue, PH is too high and plant is in nute lockout resulting in inabilityto uptake nutrients. Only way to get it down is to flush up to 3x with water PH’ed to 6.00. Take reading at that point and test again. Continue to flush until you read 6.0, let that dry out and water again with 2x nutrients and water at 5.6, that should get you down to 5.8
With coco, you want to try and stay at 5.8 PH, the PH ranges you are using is for regular grow medium.
Thank you for the guidance and insight especially as a OEF/OIF veteran myself to another veteran.
Soil/outdoor has been norm when it comes to growing plants haha.
Coco is new to me altogether so that makes sense. I tried flushing earlier this week twice with a lower pH base water which after i tested and had higher pH runoff so not to sure if that helps either.
Is this salvagable you think or should I wipe and start over clean with whats learned with this mistake?
You might want to reconsider putting FF soil in your coco, two totally different ph needs. If you are torn between coco and soil, consider Promix. It’s considered soil less so you run it at 5.8 to 6.1 and water less than coco. I grow in soil and Promix and perlite (my fave). If your gonna run coco, let me introduce you to @OGIncognito , he knows coco.
You can use either, HP has more perlite than BX. Otherwise, they are the same. I use BX but add 40-50% more perlite. You can add castings, bone and blood meal and a bit of wood ashes to it to make super soil. I prefer to feed mine as I know exactly how much and what they get. Good luck!
