Plant issue

I’ve woke up this morning with these brown leaves around some of the bud sites on just this one plant I I gave just ph’d water at 6.0 yesterday with the ph of the runoff coming out at 6.1 and the ppm at 350ppm. It’s in coco 70/30 with perlite. I have began watering daily the last 4 days and ensured a decent amount of run off. I use rain water when watering. Temps get to 84 during the day and 65 at night time. Any advice would be super appreciated. The plant in the front left is the plant with the issue.
Cheers

Why are you flushing with low ppm during this crucial stage?! Should be in the 1000ppm mark right now.

What exactly is that browing, i don't know other than it looks very much like a Boron deficiency, but fucked if i know someone will say other wise or take a stab in the dark .

botrytis

More info would help..
Like what are you using ( nutes)?
Ppm is very light in my opinion..
Rain water isnt very consistant far as ph goes.. but none the less its normaly good water.. ( unless its city rain)

flushing the plant? I’ve been told by multiple different people that I should be watering daily to ensure there’s no salt build up and as coco needs to stay wet instead of drying out? Have I been given the wrong information? I feed nutrients 1 water then give Ph’d water the next is that not the right thing to do?

im using the classic canna nutrients flower a & b, cal mag, pk 13/14 and then once a week I give canna boost rhizotonic and cannazym. I’d say it’s low as I watered with just water yesterday and then again today to get an accurate measure of ph and ppm. nah I live in the country so no city rain

The seach option on this site or any major search engine on the net solves alot of simple question.. granted im guilty for doing the same thing as O.P. when i first started cannabis forums..

I use exactly the same nutrient line my man, feed every single watering..do not flush the medium if you haven't got the online chart it comes in handy

yeah I got the chart when I bought the nutrients do you feed all nutrients or do you just do the boost, rhizotonic and cannazym once a week?

yeah I’m definitely guilty of it I just never back myself and I’m usually pretty close to what’s wrong but then I still ask anyway to make sure

Feed canna flores A-B, boost, rhizotonic and cannazym every watering, i do mine every second day and PK for one week only around week 4 or 5 as the chart says. Works a treat

true I’ve been feeding the pk for 2 weeks would you say it’s just a waste now?

No you should be feeding the plant nutrients every single day. Never use just water with coco.
