You're probably onto to something with the Ca/Mg. I've seen it in LED grows before and I believe I've read that LEDs cause this deficiency more than other types of light. Just add CaliMagic to each watering and it normally sorts itself out.
Watered two days ago so no need today ... deficiency appears to be lessening ... soil ph 6.4 ... I believe they have just started to frost in the past day or two ... seems late ... first time I've seen the temp below 80*... may have been from when the air was on two days before ...
Photo is last year's Nirvana's auto Blue Mystic at same age as this grow ...
Much heavier budding ... Lot more Frost ... :dance2:
I did a little research on last years Blue Mystic grow ... 3 main differences between last year's and this year's ...
1. 368 watts of LED v. 200 watts.
2. Blue Planet Nutrients 'Farmers Pride' v. soil tab & Roots Organic Buddha & Sea Grow
3. Last year's grow was air conditioned / this years isn't. Due to a bigger LED
Temps only about 5* hotter in this year's Grow ...
I haven't seen heavy frost since I stopped using Farmer's Pride ... :tiphat:
I switched the light to 24/7 on the last visit ... didn't help it to frost up but it didn't hurt it either ... 'P' deficiency appears to be controlled by nutrition ... still some Mg issues ...
