Not sure about that browning. Once they're damaged like that they won't come back. Get your Ph in check with a couple straight waterings no nutes at 5.5 ph with a bit of runoff (may see a temporary shock from ph change) then resume feeding again around 5.8ph +\- 0.3ph every time, straight ph'd water+calmag with a bit of runoff every fourth watering. Browning of them leafs could be from excess salts due to lockout, not for sure though. Watch your new growth for signs, damage is irreversible on them lowers.

Not saying this is what it is. But I just dealt with what I thought was a def or ph imbalance etc. Turns out I had "Root Gnats". Have you seen any gnats flying around lately?

IMO looks kind of like K and Mg.

What strength nutes are you feeding?

Ppm EC TDS etc?

If you're testing strength then what is the runoff testing for nutrient strength vs what strength is going in?

only have a ph tester no ppm ec or tds meters
and have only been feeding 1/4 strength go box nutes and from what I've hear the GO line is very hard to burn with. Also its still eating any veg nutes left after lightly flushing switching to flower when I feed next should I have switched to flower nutes earlier?

What's the NPK of the flower nutes?

What's the NPK of the veg?

I use a 5-4-3 start to finish and have used a 6-3-8 from start to finish.


Also something to bare in mind is that with every watering in soiless you should be feeding.

with my go box for some reason I have to use the cal mag every water and the others every other or I get funny spotted leaves every time. also the bio marine would probably help this always brought out the green in my leaves for sure

how much do you use per gal or 4 liters? is the feeding chart a good schedule to use? have you ever burnt plants using it? Thanks will try using the bio marine and cal mag too. any other info you have on the go line that's worth sharing would be much appreciated have been looking for someone who also uses GO.

gave it its first ro watering at a PH of 5.5 2 days ago runoff tested 5.9. The browning and leaf dropping is continuing will add some pics does anyone know if this is a def or nute burn?I need to know.

That damage is nute burn and they are also showing signs of early N toxicity, aka the claw is beginning.
