New growth on top yellowing with pix, help!

I have 5 plants just put into flower 5 days ago. The new growth on top looks to be yellowing, as the plants all look healthy and bottom leaves are all healthy and dark green not sure what is going on. I'm feeding them fox farm neuttz and haven't started them on their flower neuts yet.could this be my problem that they are in flower and require flower neuts now? I'm using led lights 1000 wat and 600 wat that stay a good foot from the top of them and ph water to 6.5 as I'm using tap and haven't had problems with my tap in past harvests. Weird thing is 2 of my plants aren't having this problem and 3 are. I add a dose of cal mag to my neuts as well. I heard that new growth when put into flower may turn yellow from plants growing so fast but don't remember this happening before. Thanx for help all.

Is the three your having problems with under the 1000 watt light?

Well I kinda rotate them around alot so they aren't under one light for that long

that was my guess and that the light might be too close. raise them up a bit see what happens.

Ok I'll raise em a few. Inches, also some leaves are turning two toned. Not sure if this is related to the yellowing.

They kind of look ok just want to grow maybe up your nute ppm up a 100ppm's. Are you adding a microbe product if not you should be adding a little bit once a week.

Which light is the 1000 - the black one?? are they both at the same height from the canopy??

Yes the black one is the 1000. I just had them under my veg t5 lights and put them under the led few days ago. Not adding anything besides fox farm and cal mag. And u think I should up neuts ?

so did they look fine under the t-5? and yes up the nute a little a 100ppm's isnt much-- if they looked fine under the t-5 and then you put them under bigger lights and they got a little faded means their hungry and growing if not then dont up anything. Lights should be about 2 feet away from canopy, and get some microbes working for you. If you do nothing but add a microbe product at a very little dosage once a week will help you more than anything else I can think of right now.

you didnt answer
are they both at the same height from the canopy?? if so and the ones under the 1k are the worst looking ones and every else is the same then raise that light up and leave the other where its at for a week and see what happens.

Your plants kind of look just fine except maybe that deficiency in the last pic. You could try to water in epsom salt at about 250ppm's on a water feeding day and see if that helps.

Yes they looked fine under the t5s. But I did kind of feed them heavy 2 waterings aho and last 2 waterings I just ph the water with no neuts. So it could be lights or lack of neuts or I over neuted. But leaves aren't giving that over neut burn so I kinda X that out. And I have the 1000 wat light little bit higher then the 600 wat. Was thinking bout getting this product for the microbes what do u think ?

I like to use these two from RAW. They have different microbes in their product although the one you picked out would help and is fine I like to have the diversity of different microbes working for me.

Maybe try feed feed water feed feed water instead of a feed water water feed water water

Try upping, or lowering, your calmag too.
One or the other, always seems to work for me.

@Bernie420
Feed, feed, water. Feed, feed, water.
Sounds about perfect to me too.
Even just much lower ppm, when you water. A little nutrient, is always good in coir.
