problem bad light refraction with glass???

[mr Hanky]

I'm vegging a california orange bud by dutch passion feminised in a new cabinet in dwc and i don't know why the leaf grow discolored and yellow striped i don't think it is a nutrient deficiency (I have previously vegged another cali o. in this cabinet and had same problem in soil) so I think it is due to the 5mm glass shield under the 150w hps that provides bad light refraction, is this possible?????? or what is my problem??????

nobody knows ?

Not the glass. And unfortunately I can't blow up that pic for better inspection .
But if you look around there's a troubleshooting form that MyNameStitch posted up... fill it out as best you can.
The REALLY important stuff from the looks of your plants is
-Res pH
-Res EC
-Nute mix you are using
-Medium
-Water source
-If not tap water are you using calmag
-Appearance of roots
-Is your res aerated in some way

Ya, like stinky has suggested, more information is needed, also can you post a better picture? The picture is way to tiny to really see it in detail.

thanks for any reply

reverse osmosis water ec 0.0 15lt
res ph 5.8
res ec 1.1
res temp 68°
cab temp 65-75°
GH nutes 1,5grow 1micro 0,5bloom
210lt/h air pump 24h
15min on - 4h off drip system
healty roots
ventilation ok, humidity ok.....




I don't know! it happens also in soil and since they are seedlings

Looks like the plant is lacking iron or something.

Ug, why did you post small pics when we asked you to not post small pics?

GH nutes 1,5grow 1micro 0,5bloom

How much of each in how much water?
Are you mixing the micros in first before the grow and bloom?

If you're using RO water.....where's your CalMag? You NEED it with ro water.

STINKSTER! Great to see you.

How did you pre-treat your rockwool before you started using it? And the hydroton?
Can you get a pH reading of the runoff as it is coming directly out of the medium, not actually IN the res?
Something doesn't add up. When is the last time you calibrated your meter (and I'm only half kidding about this, but is it a Hanna? lol)

 

[Weedhound]

Or get some CalMag......

I think you need to up your nutes a little bit. Everything listed looks good and the roots look ok (no pix) but I am going with what was said. I don't think you need to get a calmag. Just raise you nutes up a bit, or just the micro. That has calcium in it along with iron.

those are some funky lookin leaves - need the bible before posting possible diagnosis no your everyday problem thats for sure
