Variegation?

[Orion]

An interesting display. I figured it must be this variegation I keep hearing about. Just the tips, lol that's what she said

That is too symmetrical to be variegation. It is more likely a nutrient or PH problem. I will move this to the Infirmary for more peeps to see it.

Be sure to tag me if I miss it!

Please fill in this form: (copy and paste part is below, this first one tell what specifically to include)

-Problem: (brief description)
-Medium/grow method: soil; soilless-- coco, or peat based like Promix, etc. (please provide the actual product name); DWC, NFT, etc.
-Feed and supplements used: include brand, dosage/strength, frequency of feeding and watering (alone); method-- by hand, drippers, rercirc' or drain-to-waste,... N-P-K #'s too if you can!
-Water source: RO/DI; tap- dechlorinated-?..... EC or TDS reading; pH (don't bother with this on RO/DI, do bother with TDS/EC though to confirm it's working well enough)
-Strain and age
-Climate: night and day ambient T and RH%; res' temperatures; any extremes in T/RH% exposure
- Light used: HID, LED, COB, combo of,... wattage; light cycle hours (20/4, 18/6 , etc.); distance to tops....
-Additional info: PH in the root zone. How long have the plants been affected?...How fast did symptoms appear?... Anything else you think might be relevant..

--Pictures including WHOLE PLANT PICS, and troubled leaves.. use normal light or flash as other light sources ruin color rendering, critical for diagnostics! Turn off the grow lights.

Wow that's an intense list. Pretty sure high temps and high pH were the problem. I've made some large ice bottles to cool the res and got the pH down to a reasonable number and she seems okay now judging from the root growth. She is two weeks from hatch today and the roots have finally reached the bottom of the basket.

Problem: discoloration and initial root dying off.

Medium/grow method:dwc 25 gal res

Feed: and supplements used: I haven't fed yet but am using mega crop only

water source: tap 150ppm and dechlorinated with ascorbic acid

PH in the root zone: around 6

Strain/age: auto ultimate / 14 days since germination

light used: one cob I think I remember they are 55w and seven 10w blue led bulbs in a bulb splitter to supplement.

Climate: around 80 degrees f in the tent 60%rh water temp is around 73.

Additional info: using hydro guard also but it is out of date.
