Advice Needed please....

Hi guys,

1st post so hopefully im in the correct section.

2 plants in same room, fed/watered at same time with same solution.

1 plant looking healthy, 1 plant looks like she is suffering a little.

A little about the space:

Viparspectra V900 at around 14"
Day temp: 74f / 50-55RH
Night temp: 71f / 50-55RH
2 x Amnesia Haze - Day 8 of Flower
Canna coco with couple inch of clay pebbles top & bottom of 11ltr pot.

Initally didnt have my PH pen so used a solution/paper test. i think the solution was old and may have given a lower reading than actual PH.
Got my Pen and measured 6.8.
And also used 17ml of each A & B in 5 litres.

Re-did my solution at 10ml A and 20ml B. That has been left over night to be retested for tomorrows feed.
Yesterday i gave them both a good run through of PH water incase of salt, still a little damp today so left them as is today.

So im stuck between a deficiency or possible nute burn.

Initial instinct thinks nute burn but other plant is loving life, leaves affected seem mainly in middle of plant with top and bottom showing tiny amounts of colouration on leaf tips.


Any advice or tips greatly appreciated.

I understand the length of time needed for these girls.

Ive already done a watering with just PH'd water to see how it responds, guess itll be a couple of days before i can tell.
Will give the poorly girl just water on next top up and the healthy one a dose of the 10A/20B solution.

Ordered some PK13/14, hoping it arrives tomorrow.

Calmag was on the agenda, however i do have some Chempak Calcium but has ratio's of 15.5% Nitrogen and 26% Calcium. Because of the Nitrogen ive not used it as i know that part of the NPK used in the A/B solutions and unsure of upping the N will do more harm or not.

Lear Learn Learn will be what im doing over the next few weeks

Epsom salt is also a good obe to use for your plants

Anyone else care to give any input on helping this poorly girl?

 

[Disco Biscuit]

Just been to check on them, healthy girl looking very healthy still, poorly girl still looking poorly.

Gave poorly girl a small amount of PH water again and gave healthy girl the 10A/20B mix.

Just got my PK13/14 but holding back off it until i fully understand how and when to use it.

Also ordered Calmag as seems using LED, they dont give the moisture to the leaves that an HPS would, so read that added Calmag will be needed.

Heres a few more pics from today (Day 9 of flower)

Just for the record, this my 1st time although ive been growing Chilli plants for past few years so have some basic knowledge of plants needs.
