Growing with rockwool cubes/overwatered/yellow leaves/

[mikiee2020]

Hi everyone.
Just found this website and hoping it could help me.
So i just started growing in rockwool cubes. Is anyone from here growing with it? can you guys please give me some advises?
So the first day friend of mine suggested to water 50 gallons for 80 cannabis, but then i noticed that the leaves started to curl down, i researched and found out that i over watered.
Now its been several days that i haven't watered them and the cubes started to dry. but i noticed another problem, as you can see on the picture the leaves turn into yelllow.
can you guys help me please
is there any advises you can give me ?
can i do anything to bring them back.

see! getting them out of the rock wool at this stage is a big deal that may well mean starting over

obvious nute burnt, if they can be safely removed and a gentle
washed the rootstock by leaving in a bubble cloner(or clean sink with fish pump)
for 24 hours then reinsert to a clean and DAMP rockwool block

if this is a large commercial grow scrap and start over as the delay would be too costing

good luck

ps few commercial growers would still use rock wool due to the risks with molds and algeas

Thank you so much,
one more question I researched that growing in soil is easier and better, do you think can I transfer them into a soil?

Sure can, use quality soil with 30% perlite or clean river sand, improves drainage and avoids root compaction
tidy up the yellow leaves a week or so after transplant to use as control points, no nutes for 2-3 weeks

transplant at days end so to recover over night, don't be in a rush to return to the lights
these in veg are surpirisingly very tough, opposite to when in flower

good luck

What are putting into the water? You measure ph and ppm? If you don’t mind me asking, how you end up taking care of so many plants? It’s hard to find the cause of a problem without much info. A lot of things can make plants look very ill
