Sure. I'm running jacks at
Pt A 5-12-26 at 350g per gal
Pt B cal nit 15-0-0 at 250g per gal
Epsom at 100g per gal
I increased epsom to 125 w no results yet. Starting water is 30 ppm feeding at 800ppm. pH 5.8-6.2 going in 5.6-5.8, 750-1050 ppm coming out
Im wondering how many ppm of cal and mg I should be feeding starting flower? I've never used jack w straight coco. Never much issue in peat based soilless. Rambling now
I've got a mix of SE and DE hps lamps. The 3 SE running 1000w alternating w the 3 DE at 850w ( my lux meters battery is dead suppose I could download an app)
Temp 78-83
Night 72-75
RH 56-62W
RH 65-75 nightime.
Waterng every other hour at 45 sec just increased to one minute.
I popped one out to look at roots. Not as robust as i woulda liked.
I transplanted clones that were VERY well rooted into 1 gal hard pots w a biodegradable fabric liner (so coco doesn't wash out the drain holes)
17 days ago.
So this far under hps for 17 days
10 days of veg
7 days of flower.
Symptoms began almost 7 days ago. I kinda let it play out. I upped the mag sulfate a bit, but not major. Thought I may have been over-watering but probably not.
Can you give us details about the nutrient solution, light intensity and distance and environmental factors. Every lil bit of info helps.
