Tell me what you think...

Soil is Bushdoctors coco loco
Nutes are remo nutrients
Was fed 3ml of each( micro, bloom, velokelp, magnifical, nature's candy and astroflower) to 1 gal watermill machine water. Do not have a ph pen at at ( any tests coming up fort ph meters haha)
I have 3 autocobs, 2 of them directly on top of this girl.. temps right now are 90.1 but been in the 70 ls and 80s past days
I'm thinking this is a mg deficiency but let's see what you all think from this picture

- looks like Ca defc. to me mate,... common in coco, and it may be that the coco isn't/wasn't well CEC buffered to begin with, which means what ca is going in is getting bound to the coco and kept from the roots absorbing it....
You know the drill, coco needs TDS/EC and pH taken going in and coming out, at about 20% run-off each time... treat coco like true soil, and shit will go sideways sooner or later,... no way around it Niz', coco is technically a hydro medium, and pH and ppm's are more important than usual vs. soil,.... get equipped or you are gambling....
How far away are the lights? this can be an exacerbating factor if too close,....

@Waira I was under the impression coco loco is still soil like happy frog but instead of sphagnum peat they used coco

I will feed with extra magnifical when she dries out.

Is CL a blend, like Royal Gold Tupur? If so, then that changes things somewhat for sure,... but not the possible CEC buffering issue... It's early enough to do a foliar spray safely, and this is the fastest way into the plant if done right... I use the kelp and 'cal parts at half strength, along with a wetting agent (critical for effectiveness) ; spray the bottoms and tops of leaves (more stomata underneath) 2-3x/week... castile soap will do in a pinch for wetting agent, just enough to make the solution coat and stick, not just bead up... dial it in first with plain water to see how much to use, usually about 1/2tsp/qt.... soil treat too!

Coco Loco is coco, but with amendments. You don't need nutes for the first couple of weeks. Fox Farm says to ph Coco Loco 6.3-6.8 and let it dry before watering. That is somewhat like soil. I water when it's fairly dry, just not as dry as when I used soil. When I began using Coco Loco, there was zero info available on how to best use.
