Cant figure out whats wrong posible deficency maybe? Pics

Hey everyone. I think this is a nitrogen and phosphorus deficiency but I just need some confirmation or if anyone knows wtf is going on any info would help. I've been dealing with the problems since I got them.

Clones are about 3-4 weeks old I belive they were given to me so I'm unsure. I've had them maybe 2-3 weeks or so. The mother is a very healthly unknow strain.
Lights - 400w MH at 24" above canopy.
Temp - steady at 76F day 68 night.
I flushed and added 1/2 strenght FF Grow Big ferts last week to see if this would help, but still haven't seen any changes. New growth is yellowish hence why I think N def. Stems are purple - Phosphorus Def maybe?
PH in 6.8
PH out 6.8
Soil mix 25% Happy Frog 25% FFOF 40% perlite 10% diatomacious earth. Drains very well needs water every 2-3 days
No bugs that I have been able to find.

So I'm pretty much stumped... lol ok on to the pics.











Need more info let me know... I put in what I could think of. Thanks in adcance

How dry is soil b4 u water? And how far down do u check soil?

Dryness test useing finger and weight to test for water. Generally I'll wait for top 3rd of soil to dry out completely and the pot to lose about half it's weight before watering. Bottom half I wait until my finger comes out pretty much clean... I don't let them completely dry out but almost between waterings.

Try trimming the damaged ends off the damaged leaves and maybe adding some calmag. I use Dutch Masters Gold and don't have all these micronutrient def that you see a lot of people having with these so called high priced designer nutes. There's not that many burnt leaf tips to say nute burn. U can try maybe upping your nute strength a lil.

What size pots r those?

I think this a PH issue and its too high. Your medium is nearly half perlite (hydro) so you PH should be between 5.8 and 6.5 not 6.8. You have Mg ,N, P lockout due to the PH being out.

I was thinking PH Lockout but when I got them they were at 5.5 PH so I've gradually raised them to 6.8. Next watering I'll lower the PH again and see if that makes a difference. They seem to be doing better with the higher PH but I'm thinking I may have just shocked the fuck out of them with the PH flux. Not sure if going from 5.5 to 6.8 over 2 weeks would shock them but could be.

Added CalMag on Sunday.

Try lowering ph like BUDS said, and give them a day or so. When they recover transplant to biger pots with a lil less perilite mix. How long are you planning on vegging

I wanted to move them to the flower room as soon as I figured out what was wrong. I'll lower the PH again and bump up the ffof hf mix a little when I tranplant over the weekend and see if that helps. I've never had these problems with this soil mix before but thinking about it make since it's mostly air with all the perlite. I've always liked well draining soil and enjoy watering them oftem. So maybe that might be the problem with this strain... Live and Learn.

So I just checked the soil they are still a little moist would it be better to let them dry out or should I just PH them now? I planned on watering them either tomorrow or Saturday anyway so I don't think it would make too much of a difference.


Edit: I don't want to make things worse just want to fix it already... lol

Thats true. I would def wait til they've reovered ad you see some good new growth started b4 i threw them in flower. Good luck and let me know how they do

If soil is still moist i would go ahead and ph them now. I would rather have them a lil droopy from water than for them to keep with nute lock out from ph being off.

Yea I Ph downed the fuck out of them couldn't get them below 6.8 so I'm just going to repot them tonight and hope that solves the problem... Rather just stress them the fuck out now and get it over with...

Something is keeping the ph right at 6.8, I'm thinking it's the FFOF but they do look a lot better then they did before I flushed them with PH downed 5.5 water still wouldn't change the PH... used 4 different meters too just FYI for anyone who want's to ask if I checked with different meters lol... we'll see what happens.
