Name that deficiency. Help!

[endive]

Hi all,

I have 3 Nirvana Bubblicious in perlite/vermiculite soilless mix, 2 gallon pots. Only the 2 with matching phenos that are exhibiting yellowing from the leaf tip back towards the stem. Seems to be the "middle leaves", not quite old growth, but not the new growth either.

They are in day 20 of 13/11, under 320W of LEDs. Day temps in the tent are 78-82º F, RH at 48%. No visible pests.

Watering 3-4x a week - Runoff is usually around Ph 5.8 - 6.
Fert sched:
Grow Big: .75 tsp/gal 2x week
0-10-10: 1tsp /gal 2x week
5-45-19: .25 tsp/gal 2x week

Molasses: 1tsp/gal 1x week
Straight water (Ph 6.2) 1x week,

I almost thought light bleaching, but after noticing the green veins, I'm thinking Iron/sulfur deficiency, but any input and or solution appreciated!

Thanks!

Re: Name that deficiency... Help!

Thanks Guys!

I stared at the pics in the "cannabis plants and pests problem solver", as well as the "Indoor Bible". All the pics started to look the same.

An outside set of eyes is good to have!

The more I read the more symptoms my plants seemed to exhibit, I think they may be hypochondriacs.
