Ripley's OG -Mephisto Day 31

Ripley's OG -Mephisto Day 31 - Nutrient Burn?

They have been in a Multi-flow ebb and flow since Day 10, flood for 15 minutes 30 minutes after lights on and then another 9 hours after the light are on.
Lightimetunnel 400w Hydroponics LED Grow Light Full Spectrum COB Reflector Indoor Plant Veg Flowering Lamp Panel - Set to 12/12 right now as I have another that seems to need it - (see my post on Jamacain Berry)
Lucas Formula ( 8 ml/gal General Hydroponics FloraNova Bloom)
1 ml/gal Rapid Start
2 ml/gal - Hydroguard - Bacillus root inoculant

Looks like chemical burn on some of these bottom leaves. which I find curious as my TSD where going down a few weeks ago as can be seen on my record. (sorry photo could have been less blurry)

-Problem: old leaves drying up and dying
-Medium/grow method: Expanded Clay Pellets/ Ebb and flow - since Day 10, flood for 15 minutes 30 minutes after lights on and then another 9 hours after the light are on.

-Feed and supplements used:
Lucas Formula ( 8 ml/gal General Hydroponics FloraNova Bloom)
1 ml/gal Rapid Start
2 ml/gal - Hydroguard - Bacillus root inoculant

-Water source: RO water
-Strain and age : Ripley's OG -Mephisto Day 31
-Climate: 65-79 (RH 55- 80);
- Light used: Lightimetunnel 400w Hydroponics LED Grow Light Full Spectrum COB Reflector Indoor Plant Veg Flowering Lamp Panel - Set to 12/12 right now as I have another that seems to need it - (see my post on Jamacain Berry)
-Additional info: Seems l notice the symptoms a week ago but it was probably happening earlier.

Thanks for any helpful input you may contribute.

A couple of pictures of a leaf all dried up and fallen off.

Can you post a pic of the whole plant?It's not abnormal for a few bottom older leaves to yellow and die off both in hydro or soil so just remove them.If it continues up the plant then some thing is wrong.Bye the way why are you running your lights at 12/12?

Set to 12/12 right now as I have another plant that seems to need it - (see my post on Jamaican Berry here)
The first plant I planted was Jamaican Berry Supper Auto that was suppose to take 90-115 days. At day 112 I was advised to switch it over to 12/12. I have one 4x8 tent so...

I'll get some whole plant pictures of this Ripley's OG when the lights are on. I think she looks a very stretched compared to the sour cracks I have taken to harvest, but between the strain and the light difference ( the SC was grown under the 600 HPS)

... huh,... this is a weird pattern in necrosis, though it looks similar to P defc.; I do see this pattern in hydro more than soil/soilless... was there a pH hiccup recently? temporary shifts seem to cause this sometimes,... Are you using any Micro? Bloom alone is not a balanced feed, there's stuff in Micro that's not in Bloom,... Confined to just these lowers, it smacks of a defc., not nute burn.. that would show pretty much all over, tips first, margins,... The lower light hours and lack of sufficient intensity might be contributing to this as well,...

General Hydroponics FloraNova Bloom is a one nutrient and does not have an accompanying micro. I believe you are confusion the FloraNova with the
Flora Series which consists of three liquid nutrients:

• FloraGro builds strong roots during a plant's vegetative stage.
• FloraMicro is used during a plant's growth and bloom cycles.
• FloraBloom is added while a plant is fruiting and/or flowering.

Whole plant pictures

Sorry - I just noticed this morning (June 12, 2017) that I posted pictures of my Jamacian Berry and have switched with the correct pictures.

temperature too high~

temperature too high~

79 degrees is too high? I thought 80 unless you are using CO2 then 90.
