Coco growers

[Mooregrow]

Just got a ph pen and realised my water/feed tank was at 5.2

runoff is coming out at the same 5.2

I know my ph is meant to be at 5.8 so should I continue watering/feeding at 5.8 and hopefully it just sorts itself out. Only one of my three plants are having issues the rest are fine other than slightly stunted and a few spots here and there. The one plant with big issues..it’s runoff come out at 4.2 and then 5.5 after watering again at 5.8 but the others dropped, there runoff to 5.1 so very confused

any ideas?

Really easy to fix. First, ignore run-off for now, it will not tell you anything valuable because you've been flying bling without a pH pen until now. Damn, 5.2? are you using well water or RO water or something?

Prepare double the amount of feed, and flush your coco out. Make it drain the hell out of your pots to wash out as much as you can. When you're done, the coco will be super saturated, so if you can increase the temperature and/or exchaust. This should hopefully kick your plants into drinking in the right range and un-stunt them and fix lockouts.

Only after a maybe 2 weeks I would start checking run-off. In all honestly, I did test run-off when I started learning coco about a decade ago, but after a couple of grows i never bothered. In fact, I didn't even bother to water until run-off, but that's an entirely different story.

Flush your coco really well with ph 5.8 - 6.0 (without nutes), to clean up any salt buildup and reset pH range - use tap water! Never distilled, rain or well water, as coco hates being watered without at least 0.2 to 0.3 EC to not screw up cation exchange potential. Literally, wash the coco off … then, give it a good 5.8 feed.

Only after you're super confident your top feed is perfect, only then your run-off will give you insight of what the exudates and flora are causing deficiencies and what not. So don't get hung up on that just yet, if ever.

Thanks a lot! I think if got it and I will do exactly what you’ve said hopefully that fixes the problem. I’m using tap water and then using ph down.. I was using a colour chart, obviously my eyesight isn’t that good haha. Iv read not to do a “flush” with autos with ph water without nutes in coco? And do you recommend to do that with every plant or just the one suffering?
