Please help!

So my HSO blue dream is in week 3 of flower and has developed this deficiency .... can someone please identify and help me get rid of it? thanks

growing in DWC under a 600 watt HPS lamp using GH 3 part nutes

Hope this helps:

First make sure pH and ppm are correct and meters are adjusted because usually that is where most defs start.

i dont understand how it could be a K deficiency im using GH nutes as directed

keeping ph at 6.0 with blue lab meter and ppm is at 725 because if i raise the ppm the plant does nothing but drink water ... so the water level goes down and ppm goes up

I think it probably is K deficiency as the leaves in the picture look significantly the same to yours but idk you might want to add some nutes (or more nutes if your using them already but not too much)

adding more nutes does nothing because as she drinks water the ppm's go way up

Any more opinions ?!

Could this be a nitrogen deficiency?!

Are you using cal mag?

Hey tiller what kind of nitrogen are u feeding with. Seems like it is possible its a nitrogen deficiency. My plant started getting nitrogen def and I gave it some water soluble nitrogen(nitrate) a week later new growth showed no yellowing at tips.

What he said...Looks like Calmag issue to me. Some of your damage is from as you said the plant not eating when fed causing nute burn from lockout of some sort. What do your roots look like? Are they a healthy white or slightly tan?

hydro nutes supposed too be in the 5.5 range?
