Are you flushing ? It's just the natural fade of the plant as it comes to the end of its cycle in flower. Nothing to worry about , it's just a lack of chlorophyll in the leaf as she fades out.

PH measuring for Organic Growers
If I’m growing organically, do I measure my PH still? I heard that the PH up & down liquid isn’t organic & that organic growers should throw away there PH meter because the soil will adjust to what ever PH level I water them with. Is this true? I’m having a cal/mag deficiency.

Advice on next feed.
So just before I water tonight I want to ask what some more experienced growers would do instead. I'm getting near the finish and honestly just want to make it there without losing too much bud production. I think my next water tonight will just be 1ml of bloom/l, inputs?

I am struggling to find out what my plants are lacking or what I am overdoing here, can someone please help diagnose what this brown spots are on leaves? My guess was boron deficiency I’m worried if I don’t fix it quick it will kill the crop :(

Low PH runoff, dealing with deficiency due to low soil PH. Added lime and PH went from 5.4 to 5.0 after watering. How to raise it safely and quickly?
I have been dealing with a nutrient deficiency so added nutrients.It looked ok but then got a bit worse and I took some runoff readings which were 5.4 and then 5.0 the next week after adding lime to raise soil PH. How can I best raise the soil Ph being that I added lime already.

To Nute or Not?
About to hit two weeks. Growth has been steady, but slow. In lambert's cactus/succ. mix. I want them to be in a bigger pot and different soil, but they seem too little to transfer atm. Do they look like they're starting to lacking nutes? Did suffer some light/heat :(

Calmag deficiency or Nutrient lockout caused by Pk excess ?
Flo+44. Probably I didn't remove Pk fast enough (left it for more than 19 days, should have left it for 15). So I reduced the nutes from 1.15 to 0.70 now, hoping to avoid the lockout... Thx !
