DP frisian dew with some issues. Advice wanted.

[KenBacon]

So, I posted this in my grow journal in the outdoor section, and the honourable @912GreenSkell was so nice to point me here and advised to tag @Waira in my post.
So here are the details. I'm growing her outdoors in full soil. She's a photo period DP frisian dew of 11 weeks and 3 days. The soil is enriched with chicken shit pellets, so she should have plenty of food. It's been incredibly hot here the last few weeks, 28°C and more with sunshine from morning to sundown, and very dry. I've watered her almost every day because of these temps, as I do with all plants in my garden. The pale leaftips are not like a burn, really more like a discolouring. And yellowing leaves below look like an N deficiency. I saw the taco'ing of the leaves, and know this is heat stress, but there is really nothing I can do about that because of the ongoing hot weather here. We are having weather now for a month that is more typical to Southern European countries. I also know the genetics are developed in the northren parts of Holland with the specific goal to create a plant that can withstand a bit of cold weather and is mold resistant. Perhaps this is why she is suffering from the heat we have here nowadays.
Help anyone?

Something I forgot: the leaves that are yellowing also have a red vein on their stem. The healthy leaves don't have this. I don't know if this is important, but I just thought about mentioning it.
Thanks!

Looks like she needs some nitrogen.How long is the growing season where you live because she won't start flowering until she gets 12 hours of darkness.

Hi, thanks for the reply. I top dressed some chicken shit pellets a few weeks ago, which are full of nitrogen, plus I dissolved some in water and gave her that over a couple of days just to have some readily available. I even have her some regular plant food with np 6-6 or something. Doesn't seem to help... The pale tips seem to be spreading, and are mostly situated on the top side of the plant. The yellowing leaves are at the bottom.
Flowering only starts here end of August, so still some ways to go.
Here some close ups of today.

Have you used any cal/mag?and ph'ing your water?Cal/mag will help your plant with nute uptake so that might help.Purple stems are quite normal on many strains and is nothing to worry about.

...no more N, this isn't an N issue... too much will screw with K and Ca uptake as well,... the pellets, are they composted at all? -- cooked down in other words... they take time to break down and release the N,, the rest is looking like P and K defc, and I'm betting micronutes defc.'s will soon follow,... you need a complete, balanced food,...chicken poop is anything but that! the heat and low RH are compounding the problems as well, messing with transpiration rates, and there not being enough of the other nutes available,.. get proper fert's going in there ASAP!

I have bio bizz fish mix, bloom and top max. The chicken shit is great for growing, but it indeed needs time to release the N. It should be that time now since the top dressing happened 3 to 4 weeks ago, probably longer still.
What would you suggest? I can give her bio bizz bloom, which is a little lower in N than the fish mix?

And thanks for your reply @Waira!

..whatever you have, or better still, can get that has higher PK and little to no N,... I think the bloom is too weak to fix these defc.'s well or fast, you need a bloom booster,...
