Deficiency getting worst

Hi there

here's a previous thread i posted when i noticed the beginning of that sign which they told me " calmag " deficiency CLICK HERE

well from there until now i did foliar spray just a few fan leaves and watering with RO water 40 PPM before ,and after adding calmag went to 180 PPM.
3 days later it was looks the same no improvement ,and yesterday was the time for the compost tea and i did .
and today some leaves looks worst than before ,no signs of improvement ,don't know how bad is it ,and how bad its gonna affect my harvest and smoke .
please check pics and advise me ,your newbie fellow grower is fked up and need some help
love ya all


maybe its not clear on all pics ,but that browny spots are mostly on 70% of the plant leaves vary from early " few spots " to late " leaves looks totally fkedup ".

Grow medi = peatmoss + vermicast + perlite + Natural living soil concentrate ( Supersoil )
2 / 5 gallon fabric pots
temps 20 ~ 23 C night 24 ~ 28 C lights on
Humidity 40~ 60 %

The damaged leaves wont ever look better so focus on the new growth.

Using RO water your going to need to suppliment cal/ mag to your feeds and water.
What is you ph?

R.O with calmag 6.5~6.8PH
last time i checked run off - PH was around 5.8 PH ,i have been told to not worry about soil PH in living soil.
yea i know but my whole growth cycle i haven't faced any deficiency at all ,but after it flipped into flower i noticed a few deficiency specially now in week 4 it become so obvious , i also thought the same about that damaged leaves wont become better again , should i remove it or let fall naturally ?
some of them are big and blocking some buds below.

Hey, how are things looking? Plain water flush then pure green coconut water might help. Also, too much potassium blocks calcium, is it possible that's a factor?

Soil with a 5.8 PH could affect P, Ca and Mg uptake.

I only know coco, nutrients with every feeding. Never plain water.

well tbh i dont know i just flush them a bit and add garden lime as other suggest ,i think they back doing fine after a week ,just a few more fan leaves getting the same shit, thanks god i didn't do heavy defoliation ,so i have so many back up fan leaves haha
i hope it just survive for another 2 weeks until harvest ,smell great so far but i think buds stopped fatting up since a week or so
but buds looks amazing ,well see next two weeks and how it goes
