Nute burn?

[Bobbiegunz]

I would ditch the distilled, that has always caused issues, maybe just some spring or drinking water, I bet you see them green up. Not sure about your well water, it may be fine by itself.

By distilled i mean left put for 24hr thats worse than straight from well? Maybe my terms are off here.

BIGGEST mistake is how often you flood!

You should be flooding 5 times in a lights on period!

This is considered a hydro style grow. The Rockwool needs to be damp and NOT dry out at all!
This IS causing a pH problem too! As the RockWool dries out...The pH is rising!

SO then. You have lowered uptake of K and Zinc (and other things) by high pH, too long. You also have way too low feeding availability, so they aren't getting enough to start with......
The plants are struggling to get what they need!

Cycle the system like this.
The first cycle right at lights on!
The last cycle right before lights out - (as the cycle finish's. The lights should go out) THis carries the Rockwool and the plant till lights on!

Space the other 3 cycles - evenly between the first and the last.....

Things will take off and you'll be very happy and so will your plants...

More points of order:

pH everyday at lights on! pH should run between 5.6 to 6.2.....Different nutrients are best available at differing pH values. The way I used to run hydro styles was to focus on a pH of 5.7 - 6.2....It is best to allow the swing from you setting it to it hitting at 5.7, to rise to about 6.1 -6.2 before adjusting it back down.

As the rockwool and the plant age. The pH will settle down and rise in pH slower.

The damage to the plants will not "repair". They will deepen in green from the needed N. The new growth will show nice fresh undamaged plant as it grows.....You will "see" improvement in 3-5 days.

Good luck

I some how missed this post, the botto. 2/3 of rockwool always seems very wet and the cubes are always very heavy i was worried if i keep them soaked it will cause root problems/over waterong withpight time for the roots to not be soaked?

no, that is not distilled, i am not an expert on well water, but have you ever had it tested? Is it safe to drink straight, or do you have to boil it first?

NOPE! Not for hydro style runs....Ebb and flow is hydro....be it hydroton, rockwool or another media that your plant is in....

I used RW in a 2x2 tray set-up to dial in for strains. The used that info in the full sized bucket systems.
