Would gentle mean 3x the normal feed flushed with just ph water ?Greetings, noble grower! I agree with Bobcat. The leaf you show reveals signs of nutrient-related distress. The yellowing with dark brown or purple spots along the edges typically points to a nutrient deficiency or imbalance. While 5.8 to 6 is close to optimal, coco often prefers pH around 5.8 to 6.2 for best nutrient availability. If pH drifts lower, potassium uptake can be reduced. Coco fiber can hold onto salts and nutrients; improper flushing or buildup might cause nutrient lockout leading to these symptoms.
- Coco often requires careful feeding with cal-mag supplements and a balanced N-P-K ratio.
- If you suspect nutrient build-up or lockout, a gentle flush with pH-balanced water might help reset.
I've had to do that until you see clear water out the bottom, then restart feedings after and i did the restart feeds at 1/2strength. Some one may have better thoughts about it.Would gentle mean 3x the normal feed flushed with just ph water ?
Yeah I was also wondering how much to come back in at. I was thinking 1000ppm but maybe that’s still too high.I've had to do that until you see clear water out the bottom, then restart feedings after and i did the restart feeds at 1/2strength. Some one may have better thoughts about it.
I know coco growers who never bring their EC (500 scale) above 700-800. There's been many people including me who have suggested your plant issues are due to over-feeding. Feeding more will not correct the issue. I would flush then go with a feed in the 700 EC category.Yeah I was also wondering how much to come back in at.

Dude I am so surprised this did not get handled. Hopefully a coco grower can help.
There are wetting agents and things to help remove the buildup. It takes a soak and purge for a while. Then restart system with reduced nutes.
There was a wonderful lady on riu that was a wiz on coco. Here biggest points were not going over 1000 until you became very familiar with the strain and ride herd on PH like you do.

I rarely go over 1.6 EC in Coco, ever. 1.0 - 1.2 veg and up to 1.6 in flower. It's a balancing act, or can be because in coco and under LEDs you will need CaMg and it eats up EC quickly. I'm favored by an extremely low ppm water source, and with ebb and flow I have total control over frequency, amount per feeding, and with a good perlite to coco ratio all helps favor frequent feedings without drowning. So, lower EC, more frequent feedings is my jam. "Flushes" for me was just one day (2 to 5 cycles) of CaMg at 2ml per gallon, pH to 6.0 and only in between reservoir changes, if even necessary.I know coco growers who never bring their EC (500 scale) above 700-800.

If I were to guess ... your nutrient ratios are off due to the salts buildup.Much love to everyone !! I have read a lot about the lower PPM for Coco, but what has gotten me in a whirlwind is I’ve been running these strains for just about two years and never had an issue going up as high as 1300 ppm so that’s why all of this is just so confusing to me as to what has changed. I am going to completely dial back and get them flushed.

I don't think a "perfect" setup exists. For most people, their success will be determined by how well they read what the plant is telling them. This is why experience is ultimately the best teacher ...If every other aspect of the grow is on point, then a higher EC isn't a big deal, and is actually warranted.
I may be tipping my hand, but I guess I rarely have a perfect setup on any given grow lol
So true. I almost don't care to diagnose much in the way of deficiencies. All I generally need to know is that something undesirable is happening and I just go straight to the source or reason for it. And it's usually something I've overlooked, ignored, or did in error that created any given problem. The cause is usually me - End of mystery diagnosis.I don't think a "perfect" setup exists.

Oh yeah I hate myself right now lmao causing myself so much miserySo true. I almost don't care to diagnose much in the way of deficiencies.
