Is this normal for week 6 flowering or is it nutrient burn

[MisfitDaddy87]

This is my first grow and I'm 6 weeks into flower I'm growing in coco coir feeding 3 times a day with RO water advanced nutrients "Master Recipe" which seems like a lot of nutrients but plant has been doing good so was just wandering if the browning on the leaves are just normal for week 6 or if I should cut back on nutrients any help would be appreciated thank you

That's not normal, I'm not familiar with the nutrient what ec are you using?

For reference my plants are 6wks also in coco with a ec of 1.7

It's about 2.1 after i add everything with ph around 6.0 sould I dail it back some and if so can I just add ph'd RO water to lower ec or do I need to make a new reservoir

Yes bro just dilute it in the reservoir that's fine.

Yes I'd dial it back a little I'd aim for 1.5/1.6ec deppending on the environment, the environment affects ec that's part of the reason for a stable environment.

Plants transpire water from the leafs the water evaporating over the day increases the ec, it's effectively getting concentrated (loosely speaking) but enough to have an effect over time if it's not rinsed away properly each day hence the importance of run off.

If you've a got dry environment the amount of water getting pulled from the leafs is more than an environment that's cool and humid, keep that in mind, if its hot/dry err in the low side and the opposite if it's cooler and humid.

I forgot to add in my 1st reply you've made a nice job for a 1st grow, well done dude.

Before you change the ec it's worth running nutrient through the coco and testing the run off ec it'll tell you if ir need rinsed/leached down, lowering the ec won't help if it's salt build up?

I already diluted down to 1.6ish and the run off is a little over 2.2 I normally try to let it run long enough each time to get good run off to prevent build up I've been doing quite a bit of research but that only goes so far and for temps I keep it at 75 and humidity around 45 but I think I'll go ahead and flush it a time or two to get the ec down to the new level I appreciate the advice and your buds look amazing maybe I can get mine looking like that after a few grows

That's fine bud, if the run off is 2.2 it's close enough to the input to suggest you've been watering adequately, nice job

Water more. Increase runoff, plants at this age use different types of nutrients, when you are not washing out enough of what you are putting in excess nutrients builds up in the soil.

To me it looks like dirty soil. 30% runoff is a good average to go for imo.
