Thanks for all the comments guys much appreciated. "AFN smoke out"
First of all some pics, everything looking well. Showing slight signs of P&K def so I've made a tea style feed which isn't looking too active but all the same I added some bat guano 1-10-1, sulphate of potash, epsom salts, molasses and EWC. I'm just chasing my tail with this soil mix really, hopefully I can see out the next 3/4 weeks without a disaster or I'll be seriously gutted after 3 months of growing these out! SC is still showing burn and it's slowly making it's way up the plants main fan leaves, don't know what to do about it apart from hope it doesn't get too much worse, the buds all great, so frosty on the SC and the RQ is putting on weight now.
Added a tube heater which is working amazingly well, brought the temps up nicely and now I'm hitting 19c at pot level with lights out.







My new mix looks to be cooking well, but I've been thinking. I'm not sure if to scrap it, and just go for a basic Subcool mix. I have half the amendments and all I would need would be a bag of Allmix, bag of coco, some Rock dust (in place of Azomite) and some worm castings. All in about £50, at least then I'll know I'm good to go. This new mix feels a bit all over the place, and I noticed when looking at Sub's recipe, he uses bat guano and bonemeal, lot's of P but not much K. I left out the bone meal and added potash in this new mix and no Rock Dust, I used Seaweed Meal. I could always add some Bone Meal. I just don't want to be chasing my tail with burn/deficiencies again, might run some Master Kush next lol.
So any advice? Still got time to get the new stuff and let it cook before I start a new run, or just use what I've got and make it work?
