New grower,leafs discolorated in the last 2 days..

[Tonkatoy]

Hi this is my first grow,indoors.
I have 6 Moon Glow plants on the go,they were cuttings transferred on 18 July to 10 litre pots.
The cuttings arrived in 6 inch pots with coco not soil,went into bat crap soil and all had been doing well until 2 days ago.
I'm in a 6ft x 6ft x 6ft tent,plants under 2 phlizon 1000w and one Mars Hydro 600w,started adding veg nutriment Bio Bizz 4 weeks ago now,would like them to get a bit more veg time in,maybe 2-3 weeks before switching to 12/12,been on 19/5 since the start.
So 2 pants started showing these marks 2 days ago,another plant looks like its got to that one as well.
I have had these pretty close together for the last 2 weeks or so,moved the 3 lights so any light spill that was just lighting up bare floor was giving light to the ones near to it.
I have used bottled water throughout.
PH has been consistently around 7.
Think I have covered the main problems etc now heres some pics hopefully

You can see the leaf discoloration in the top pic,to the left,there is a tiny hint of purple to the color as well,pics dont show the true colors too well.

Hello and welcome to the forum.
The dark purple stems lead me to believe you are dealing with a phosphorus deficiency, The purple on the leaves confirms my suspensions.
I would say that the light colored striping on leaves is a magnesium deficiency.
Color wise the dark green of your plant looks like it's nitrogen levels are fine. The Purpling and magnesium issues lead me to believe you are dealing with a base mineral deficiency.

Any chance you have access to fresh clean wood ash right out of a stove or fire pit? If you do.
Mix 1 L cool dry wood ash in 5 L water. Mix well let stand over night. You can remove anything floating with a strainer.
Use the clear solution 50/50 with water. PH it 6 - 6.5 . Really soak your plant with this. Then add the clear wood ash water to every watering form now on.
10 water 1 clear wood ash solution. You don't need all the gray stuff in the bottom, all the plant available minerals are in the clear solution.

I'd suggest you also give your plant a snort of Cal Mag. If you don't have it add a table spoon of Epsom salts to a liter of water.
Take a ppm reading of your 50/50 wood ash and water solution. Add the magnesium solution until you get a reading of + 75 ppm.

My wood ash solution runs around 850ppm. 50/50 is around 500 ppm. So add magnesium solution to the 50/50 until you get a reading in the 575ppm range. PH it a little lower 6 - 6.5

You could also thin this out 10-1 and folier feed a few times after watering. See how she does.
The wood ash is a broad spectrum plant available mineral inoculate. And will take care of about any deficiency your plant is experiencing. provided your ph values are correct. 6-7 range.

There is actually plenty of Magnesium in the wood ash solution but adding another 75pm won't hurt the plant.
If you want to veg her another couple of weeks add some nitrogen based fertilizer to the 50/50 before deep watering. Go easy you don't want to burn her now.

Thankyou for replying,top leaves on one plant are starting to curl up a bit,its well over a foot above the LED as well.I dont have access to wood ash,I'm in the middle of a city,no fires to get ash,if I started a small fire somewhere I'd have fire engines turning up.
Is there another way to add phosphorus and magnesium to deal with the deficiency?
Anything that can be bought?
Thanks again for replying.

phosphorus and magnesium

Would just using calmag help with this?

 

[Tonkatoy]

Guy at the hydro shop said the deficiency caused because it was stressed caused by temp drop.could have been when it went cooler and I'd left windows open ?
I got some bio biz calmag,going to use that along with putting a small layer on top of bat guano.Thats what he reccomended along with raising the temp,temp is usually around 24-5 degrees he says it should be at least 28,i disagree with that.
Says on the calmag 0.3-0.8ml per litre.
what I'd like to know is how do I carry on feeding with nutriments to carry on vegging,it'd be a few litres of water on each plant if I do calmag and feeding,thats going to flood it no?
Any ideas how I'd go about this please?

You will have to excuse me if sometimes I dont seem to make sense,I'm on the autistic spectrum so dont always seem,well,whatever normal is?

Take a look at Schultz liquid fertilizer for cactus. it's 2-7-7 would bump up the phosphorus and potassium without adding a lot of nitrogen.
Cal-Mag would not hurt. Will fix any upcoming issues with Magnesium and calcium.
