I have noticed some light coloured circle patterns on the very edge of my leaves but when I wipe it with water it disappears but I am sure they are returning pretty quickly after wiping

I have only just added the 600 w hps inbetween the two leds . 600w viperspectra n 450 viper too . Anyway I hope you can see a bit clearer ?

I don't think its anything

maybe you dropped some nute drops or something

just treat them to prevent the mold your looking at getting

Hi again I don't know what silica or amaza is mate but it seems OK now anyway no new spots . Please could I get some advice if these look OK now at day 31 from seed . I wonder if they are too bushy and also I hope if anyone can tell me if they are female by these pics below . Thank you for your previous advice by the way , really appreciate it

As far as the white spots I think that's just residual mineral from water (mostly calcium) or some salts from nutes.

To test the theory, mix up your normal water w/your normal nutes and put a few drops on something dark and non absorbent like a trash bag or any other dark plastic thingy. Let the drops evaporate, and I bet you will see exactly what you are seeing on the leaf.

Plants look good BTW

Thank you I could actually see some of the same kind of spots on the taurpaulin/ sheet on the floor from minimum drips after runoff . Does this mean it is what you say and nothing to worry about . Also I did think that the plants was too compact and bushy but will that all stretch out in flower ? I topped them all today about 7 tops on each plant .

And they all seem to get burned tips at 450/500 ppm with canna nutes but manage fine with 300-400 ppm is that normal ?
