Clone help

so took 25 clones , some
Took forever to root . I think I got some
Bad clonex , I ordered a kit off amazon and when I went back and looked at the date on the kit it said from 2012 so no tellin how long it set on a hot or shitty place , well half of them clones died the other half took forever , took another round of clones using new cloning gel and oasis cubes this time and in a week had lovely lady's ,. Well there I guess boyt 2 weeks ish or lil older now and I was just feeding light nutes and rapid start , this last round I fed bout half strength nutes flora duo a and b , rapid start diamond nectar florolicoius plus . Problem is several of the clones are turnin yellow my PPMs I fed this last time were 480 ish water ppm or 107 .. Was gonna up it a light lick but seems rather odd they turning yellow with that dose of nutes . Temp is 78 humidity is 58 good air , lights around 18 inchs 400w hid and 220w led ... Up the nutes or I got another problem ... Clones r smaller the usuall but didn't have a designated Mother as the time so was using what is now my
Outdoor crop ...

So look droopy. Over watering maybe? Did you poke holes in the bottom of the solo cups for drainage? Ime you dont need all the extra nutes just a good veg and bloom, calmg and a sweet is nice for flower.

I haven't over watered been waiting till they dry out . Nutes been light like normal never had issues , looks like there gettin a nitrogen def but I'd hate to keep on em , my last two waterings been with nutes so idk , two or three days ago they was Prayin now droppy and it was a day before they was prayin I watered now droppin so idk , hope the bastards ain't dien

Just water with ph balance... No nutes

That's my plan this next round , just concerned bout the leaves lookin like a def , they was a good lookin green now comin yellowish

Mix a supersoil..happy frog

I run happy frog , FFOF and light warrior , for my
Indoor , outdoor I run a super soil that I've near perfected , knock on wood

If your clones took awhile to root then yellowing is normal. The xutting use up a large amount of their stored nitrogen trti g to root and stay alive, without roots they cant take up nutes. Dont under or over water and give them time and PHd water with calmg. Mycos and a root booster are great for young plants.

These plants have been out of the dome
For 21 days in dirt , been givin light dose of nuts for last few waterings that's may 4th

Then yesterday All the yellow ones were basically dry this morning , gave em ph water only see what happens... Took one of the smallest
Ones out of the cup lastnight and it was full of roots so this next feed I may up the dose see what happens . Makes no sense they was lookin good since poting ... Now I've never had
This issue with any of my
Plants guess I been quite lucky but will them leaves gain there color back or will it
Just be new growth and those leaves
Are fucked .... I think I screwed up to , I usually use FFOF and happy frog but I ended up using light warrior , so mayb I need to go heavier on the nutes ..
