ratdog Posted January 18 Share Posted January 18 hello all, i've recently switched to coco in the hope of combatting my soft water issues, but i seemed to have fallen at the first hurdle i potted up my deficient plants on saturday, they looked happy for about 24 hours then started sulking. i mixed nutes to 1.5 ec as according to the ionics bottle directions but think it may be too much? ph is 5.5-6 my ph pen is a bit crap tbh. here's a pic from just now, a few are ok, but most are not happy. should i repot with fresh coco and feed at a lower ec? of flush please help! crispy leaves were from before, and this is near lights out Link to comment Share on other sites More sharing options...
monkeypig Posted January 18 Share Posted January 18 (edited) Are they warm enough mate? Your pots look a wee bit dry for coco too. Obviously don't overwater, but try to avoid too much wet and dry. E2A electrician time - raise up those electric bits to the right and pleez dude, get a new stuffing gland on that open cable access.

Your pots look a wee bit dry for coco too. the room is at 28 and they seem heavy enough, i have been watering a little, ive had issues with over watering before so trying to be careful. so 1.5 ec isn't too much?

mikeydoughnut Posted January 18 Share Posted January 18 1.5 to me seems excessive but not on pot up. I watered through my last pot up at 1.6 until the run off measured 1.2. I’m battling cold though so have to keep the light and feed aligned with the heat. Also 6.0 seems to be the sweet spot for me. I wouldn’t go lower. Especially given calcium uptake is best available at 6.2 - possibly bro science but knowing different things are best absorbed throughout the ph range it kinda makes sense. My first port of call would be temps but if environment is sound test your run off and see what’s in that there coco. If you don’t go abit heavier on pot up you’ll be pushing loads through to get your target EC. If you don’t push enough through they’ll be going hungry. 2 1 Link to comment Share on other sites More sharing options...

The intense I've been running for ages seems to be happier running high EC but depends on the feeds used, and also running LED seems to want higher EC. Make sure you are watering to run off , but try raising them (stick them on upturned saucer ?) to stop them sitting in run off. 1 Link to comment Share on other sites More sharing options...
Mr mcgregor Posted January 18 Share Posted January 18 If they've a decent amount of roots..?,fertigate til you get 20% run off. They'll pick up in no time. Don't be shy ,it's not compost! 2 Link to comment Share on other sites More sharing options...
GSZZ Posted January 18 Share Posted January 18 Cant add much more to whats already being said, 1.5 ec is alright as @monkeypig said it depends on the food used and composition, and they do look like they could do with a bit more water going through the pot - and I know 28c is alright, but I'd honestly get it a bit higher to 30/31c, try and keep RH between 60 - 70% also. 4 Link to comment Share on other sites More sharing options...

I tried that in veg after fatboy suggested it as a way to raise humidity and it works excellently. 2 Link to comment Share on other sites More sharing options...

smilertoo Posted January 18 Share Posted January 18 I must be lucky with Scottish water, never measured any PH etc in my coco. I did make some risers to go under the pots though. 2 Link to comment Share on other sites More sharing options...

Coir holds a set amount of air, so as long as it drains and isnt sat in its own filth you wont over water unless room temps arent ideal - but that'll be sorted going forward now you've turned some knobs (oo err) n that. For some perspective, after I water them in, I miss a day and then water again, and then after that point I water everyday even though the volume of solution going through the pot might only be a few hundred ml until run off, that increases day by day until they need it more than once per day. 7 Link to comment Share on other sites More sharing options...

Black Shadow Posted January 18 Share Posted January 18 Wrap the pots with bubble wrap, a couple of wraps Put a meat thermometer in at least one pot Your feed should be @26*C and feed to 10-20% run off, twice a day at least, from day 21 in flower I feed every 2 hours Use a brand name Calmag Clay pellets on the top stop evaporation and disperse the feed, coco is very easy to make boggy Any photo of the base of the pot, like roots coming out? 1 Link to comment Share on other sites More sharing options...
