I moved your thread into the Infirmary where you are more likely to get some help. There will be many opinions so hang on to your handlebars
There are many things that can be happening. First off layering soil can be a problem in itself. Due to the dynamics of water flowing through soil whenever a new strata is encountered the water must fully saturate the upper layer before the water will move to the next layer. I don't think that is the problem here but next time make the soil in the pot homogeneous by mixing it all without layers.
Answer the questions in this form as best as you can and I will look to see if I can make a better guess as to what is happening:
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.
