HELP! Still having a problem with my girls leaves

[Trimmings426]

Can some one please tell me what this is? I thought it was maybe Nute Burn but now thinking it may be a phosphorus deficiency. I can't put my finger on it and before something definate happens to my girls I need some help and advice.

What's your Ph?

[Trimmings426]

I checked my run off on both plants when watering tonight and pH was around 6.5 range.

Howdy Trimmings426, The last couple of photos look, to me, like critter damage. Have You looked on the under side of the leaves for bugs or eggs?

Could be nitrogen deficency

[NAKEDGARDENER]

I think that if you try pulling off one of the yellowing leaves at bottom and it comes off easily, and it’s limp to the feel then yes could be nitrogen, however if leaf doesn’t come off easily and is still kinda firm ten it’s my understanding that it is not a nitrogen def.

[kingfish]

It doesn't say what you've been feeding them. My uneducated opinion is that it has too much nitrogen. Just by looking at the bright green leaves.

[NAKEDGARDENER]

Yep you’re right kingfish I didn’t see what was written. Certainly ph is good. Maybe it’s what he’s feeding em.

When problem started I was feeding with tap water and medium is FFOF. After 4 or 5 weeks with only tap water and CaliMagic and Clean Kelp Extract i started feeding with Fox Farm Organic Soil Trio, Big Bloom and Grow Big at half strength. Was having drainage issues and added some Vermiculite and Extra FF Happy Frog and stopped with the Organic Soil Trio cause of the nutes in the extra soil I added. After researching and looking at the symtom checker I thought it to be a phosphorus def... Sorry not been on site with answers to your help got odd hours at work days and nights always on call. Thanks for the insight, could my diagnosis be right?

[kingfish]

Trimmings, if it was me, I would give them nothing but PHd water for a while. By that I mean 3 0r 4 waterings. Let them get king of dry between watering. But that is just me.

Could also be overheating and/or high humidity imo.

[Trimmings426]

The temp is at a regular point always, (Lights On between 73-79) (Lights Off 63-65) and it stays that way, got my hygrometer set to record daily temps and humidity range. I use a humidifier cause humidity gets low without it, around mid 20's and lower. with the humidifier humidity stays between 45%-49%. During flowering I use a dehumidifier at night when lights are off cause humidity gets higher at night here when lights are out and also I got the humidifier off at night for the same reasons.

Kingfish thanks for your note and yes that is exactly what I was thinking mysely infact that is what I started doing for my last feeding, so I'll do this for the next 4 or 5 waterings and see how they are doing then. on that note they were looking a bit better today , they were both looking up more and not so much laying down and droopy so maybe they have already started to get better, thanks again King.
