i guess i reposted a couple of them.
last 2 runs this is happening, same everything as always.
same temps, humidity, feed, PH, water/feed schedule, everything the same as always.
only difference is a new batch of GH flora series and new pro mix hp.
anybody thing bad nutes or pro mix?
or maybe crap seeds, these are my own seeds, but haven't had any issue with them before.
i'm stumped

and yes i let them dry to much and just fed them.
also lights are the same as always

I just had a somewhat similar issue that was diagnosed to be light burn. In my case, I thought my light timer was turning the lights off, but it really was just keeping them on 24 / 7

glad you caught it but, not happening with me.

thing that stumps me is that it looks like calcium deficiency, but calcium is immobile so that starts at the top. this is everywhere except the top.
also looks like n deficiency because of the lower leaves, but my feed hasn't changed

What's your water source and numbers for pH/feeding?

What's your water source and numbers for pH/feeding?

tap water with PH 8+ and feeding full strength GH flora series as always. after mixing nutes, in correct order, i PH down to 6.2-6.3
tap water is 35-40 ppm but i use GH for soft water

also, 1st feed is full and i use about 1/2 my 5 gallon reservoir then fill up with water then PH again before next feed. then str8 water for next feed.
so feed full then half then nothing

First time that’s happened? I had a good couple weeks of less than ideal watering consistency and was noticing some adverse effects. Just throwing that out there.

something might be getting locked out. Have you checked the EC coming out vs what’s going in?

promix has ph buffers shouldn’t be using ph,.
anyhoo looks underfed?

 

[GNick55]

you do have tacoing leaves, leaf edges curled up?
you sure your light is fine?
do you have gnats?

To much nutrients i think possibly light to close

i was under the understanding the buffers didn't last that long in promix so i've always used it. and considering my water is ph 8+ i'd be scared not to.

no gnats but i did have some thrips at the very start but dealt with them using pyrethrins/
i know phone apps aren't 100% but lights are at 50% and app says 455 pphd

you might be on to something there. i checked my diary (i forget shit) and i am watering heavier because 3 runs ago i noticed roots weren't going to bottom of pot, and thought more water/nutes would help that.

I only use scottish bottled water and cocofeed a and b nutrients in 100% coco coir medium but next grow i be using a 70/30 coco coir pearlite mix to see how that goes and im getting a 720w light for my 1.2mx1.2mx2m high tent the lights just over 1100x1000 so as tight as i can get as the 4 cheap 2000w leds draw only 80watts each. And a pain for getting into water.

Has to be 6.5 to 7 max ph
