Mars Reflector 96x3 Mix Up Grow

[Peteey010]

Saturday again time for a quick update. HB and WTR are 17/19 days old now and are growing well no issues there going by the size of the leaves already I think they're going to be quite big.
The 2 MG and PE are about 7 or 8 days now not alot happening there as they're still putting down roots but I expect them to take off in the next few days.
Now for the photo's.....one of the NL in coco is coming along nicely now putting out side branches and top growth just a slight discoloration of the leaves, the other NL isn't doing as well but is still putting out top growth but has more discoloration and the SR is like a bit of both she's growing and starting to put out branches but looks a funny color.
I'm adding 1ml per litre of cal/mag to each feed so any ideas as to what it could be or is it just because they had so much damage done when they were seedlings, I'm not too fussed about losing the photo's as the tent will be pretty full with the auto's in there

Can anyone tell me what this is the start of..The leaves are going light green from the outside in.
Ph is 6.1 ppm is just over 700 and daytime temp is around 25c mark
Well the SR and one of the NL came out today. They weren't recovering so the extra space will come in handy later.

Sure seems like magnesium defiency to me. Magnesium is best absorbed between 6.0 to 6.5 pH so that should be ok with your system. Hydroponics and LED's combined really can make some strains eat that stuff a lot. If these babies have had other issues as well before then I guess the underlying problem would be totally out of my knowledge. Seem a bit odd that all the leaves are having this yellowing and not just the older ones..

I'm not convinced the LEDs have anything to do with it. I've grown probably 100 plants since I got my LED lights, and I've never had a cal/mag problem, other than that was caused by my water. something in the water caused lockout. When I switched to RO water, my problems ended. What water are you using? What nutes? Supplements? I do agree it looks like Magnesium Def You need to check PH before to go adding Cal/Mag though, as it could be just lockout.

Thanks Pop and Med
I calibrated my ph pen tested the water in the reservoir and got a reading of 6.9/7 oops.
Added ph down got it to around 6.1/6.2 now. I'm gonna give it a couple of days see if that makes a difference.
It wasn't an easy job either once I found out that ph was way off I had to lift the autopots from their trays let them drain empty out the trays reconnect everything and them flush out the feed pipes, I don't want to have to do that when they get bigger.
I'm not going to add anymore cal/mag just yet as the reservoir has 1ml per litre already

Hello Peteey010, is the PH issue solved yet?

 

[Peteey010]

Yes PH is now at a steady 6.1 just got to wait a couple of days for them to get better, should be ok the ph was the only thing out.
The lights are doing a superb job with the other plants no heat issues temps at 25/26 daytime and 21/22 nighttime, humidity is 45%, ppm is 650 all is good in the tent :Sharing One:

Good to know Peteey010.

Ok so that's another set of seeds gone down the drain.
I seriously messed up again so I'm going back to basics and what I know works from previous grows.
I pulled them all today as they were just getting worse and worse no signs of recovery in any of them.
The soil was like a bog and the plants had no roots so I guess autopots are not for me plus in my error and haste to correct things previously I put vermiculite and not perlite into the mix so that was just holding water and nutes causing death by acid drowning.

So I am now going to go back to normal dirt (john innes #2) in normal pots fed with the same nutes I used on tha shiznit and purple amnesia so I know that all works fine.
I will still be using the led and have asked and expert to guide me along the way.
Now down to the beans I've put to soak
5 Max Gom from autoflor.es for the autos plus I have put 5 NL and 5 NLxOG which are regular photo's (they can stay in the polytunnel for veg and go in the tent when the auto's are finished then any males can be picked out)
I will keep everything here so people can go back through the journal and learn how not to grow
Wish me luck I think I need some at the moment

I feel for you. I'm new and I know I have been overwatering. I've lost 3 seedlings (out of 6) due to most likely:
