Thanks for your reply. If I could pick you brains a bit I'd be most grateful. The coco was only watered yesterday and the topsoil is still damp so it must be the lighting making you think its bone dry. I have recently let the topsoil get bone dry down to my second knuckle and I thought this was advised to let it dry right out so the roots search for water. I think you may be onto something though and maybe I am letting them dry out too much. I have always had problems in flower with salt buildup and very low pH giving me bad deficiency symptoms around the 4 week mark into flowering. How often would you be watering a plant like this size in a 5 gallon pot?Add another feed. Your coco is drying out too much. It should always be wet. Your top inch looks bone dry. This will swing ph as those salts build up and you get all sorts locked out. And that twisting is definitely comming from a ph swing.

Been there .Coco is not soil. You don’t water it the same way. I grow in coco and I would water that size plant twice a day at this point. Coco likes multiple, low EC feeds a day. I water my fabric 5gal pots up to 4 times a day in mid flower.
With coco;
If it’s wet, water it.
If it’s damp, water it.
If it’s dry, you fukt up.
Yeah, I can see how that would be a huge pain in the ass.Been there .
Its tough to run different mediums in the same harvest. Different ph and different watering procedures all together.
I have only ever grown in coco so I wouldn't know the difference. I was taught to let it dry out a bit so the roots get bigger searching for water in the early stage. Maybe this advice has been causing all of my problems over the years. I manage this with great results in seedling stage as its very clear when they are dried out and ready to water. I have been told to water 10 times a day in late flower (autofed of course) which I haven't done to be honest. Not sure why I ignored this advice. I do worry about overwatering and root rot if they aren't allowed to dry out and also fungus gnats as the pots are always kept soggy. Maybe if I use nematodes more frequently I can avoid the gnats. I've been taught to use 80% RO water and the Heads 6-9 formula using GH flora series line of nutes and to always hit 1.4EC and pH of 5.8. With the breeds I e chose to grow I've always had calcium problems so I've also been adding calmag. What sort of EC do you water at if you are watering frequently? Thanks for the advice by the way. Just upping my watering frequency may revolutionize my growing. My massive salt buildups which really mess me up around week 4-5 flower may be due to watering only once per day at that stage. Woupd you really recommend watering little plants like that twice per day?Coco is not soil. You don’t water it the same way.

I admire your fortitude. You have probably had some frustrating times, but you kept at it and got to harvest. I guarantee you (as much as some guy on the internet can) that setting up auto watering and giving multiple feeds a day will revolutionize your growing.
The “water and wait until dry” is the method used for soil. Works great for soil. But as you know, doing that it coco will lead to salt build up. Which will cause EC spikes and pH swing in the root zone.
My White Widow plants didn’t like more than a 1.5 EC or I would get tip burn. A 1.2 EC seemed to be the sweet spot for me. I fed 3 times a day in flower to about 20% runoff. I kept the pH around 5.8 for awhile. But I kept getting leaf twisting and blotches only on one side. I raised the pH to around 6.0 and the issues improved greatly. Yes, Gnats are a problem. I use some yellow sticky traps to keep thier numbers down and I’m going to try Gnat Nix this next run.
Don’t worry about overwatering coco. Although contrary to popular belief, coco can be overwatered. You have to try really really hard at it. It has excellent drainage qualities and you shouldn’t have any overwatering issues. As for the root health? I use Bio-Cozyme in my reservoir as my enzyme product. It keeps the drippers clear and “eats” up any dead organic matter. I also give them a weekly microbe tea. I use “Recharge” super microbe pack and some added kelp, bubbled for 24 hours and then subbed in by hand for a normal watering.
Yes, feed that plant twice a day. I was feeding these clones twice a day. Auto watering will be a game changer for you. And it’s not that expensive to put a decent system together. Good luck.
