Indoor Leaf curl what causes this?

[Matteo21]

I have some think different in a hydro setup. Flood and drain table to be exact. PH is 5.8 and veg nutes at 500PPM. I have not had much fluctuation with these numbers as I check and adjust every day. Any advise would be greatly appreciated.

What are your temps like mate? Is it hot in there?

Could it be Mg def?

Nice chart Hugo. I saved a copy for future reference

over ferting should cause leaf to curl itself downwards, not upwards.

I'm not into hydro, but aint is supposed to be allways "overwatered"?

 

[Hugo]

It's a great tool

sorry but is 500ppm not alot??????? seeing that he is still using veg nutes?

I looked at the chart and it certainly says Mg problems. The person at the hydro store said I didnt need any magnesium supplements if I was not using RO water and that my tap water had enough to make the plants happy. I wish I had more experience this is my 1st hydro grow. Other than the curl the growth is unreal compared to the soil grows I have done. My temps are high 60F 55%humidity
