Should I just start again???

[Popeye]

Opinions please I have cookie kush and big bang currently in 6ltr pots I accidentally burnt them after transplanting into the 6lre pot 2weeks ago and Iv flushed them twice since and started back wit quarter feed yesterday didn't notice any improvement today. They are in plagron coco clay pebble mix temp between 25 n 27 IV been using rain water pH seems fine between 5.5 and 6 but the humidity is a bit low between 30 and 40 precent.. I don't know if I should scrap them and start again as I don't want to waste soil putting them into 15ltr autopot system as Iv just got new air domes etc so don't want to waste all new stuff on shit crop but if people think they look worth safe I wold consider.. I have some blue dream from humbolt in my fridge should I just start them and say bye bye to the others??? Any help appreciated

OK i'm gonna take a shot. I'm thinking by looking roots are suffocating perhaps over watering. I don't understand but i see this used by EU growers why the stones are on top is it to hold moister? I know these are used for DWC or hydro. They need time to recover now. The droopy either from to frequent waterings, cold temps the yellowing from no nutes and flushed out soil. I would try and correct the mistakes for further plant wellbeing. I hate tossing plants even sick ones, i would treat them easily with low dose NPK allow to really dry by feeling the weight of the pot lift it, know the difference between needing water and just watering cause it's been 4 days. They can recover, but do you have the time and patience to see? It's a 4 month commitment with photo period strains.

The stone are on top because the pots consist of 60%clay pebbles and 40 %coco.. Yes might give them another week in the 6ltr pot I think they might come tru wit some TLC u think humidity levels are problem at 30 - 40 defo not 2 cold never goes below 20.. I always lift the pots for watering so can't understand y they look over watered I suppose once I can get them healthy b4 flower yield should not be affected

I agree with SoOrbudgal maybe watering too much...harder to tell with pebbles and coir and maybe too warm for the strain. Start by dialling back on the watering. if you are watering every 3 days, change it to 4 and make sure that the pots have good drainage. Remember to give nutrients once per week not every watering.

The schedule that works for me is when I flush with PH'd water I wait 4 days. then I water with nutrient mixed water (PH's after I add nutrients) and wait 3 days then repeat. When i do plain water I make sure I use enough to see 10 -20% runoff/waste.

40% humidity sounds okay but remember some strains like it humid and some like it arid.

For veg I would try to keep the RH around 65%, to low damages the leaves, and then they dont do their job any longer.
I see no reason to scrap these, and would suggest recovering them for the experience. It will make your next grow better.
