Different plants than my previous post.
Night temps 85
Day temps 67
Aero/hydro hybrid
Bunch of 600 watt hid
Hard water

Wondering about the yellow in the leaves. Is this light burn?

That looks like a nitrogen deficiency from not maintaining veg ferts through the first two weeks of flower, the stretch.

Def nitrogen tox. How much are you feeding them and what are you feeding them?

Try and keep Potassium:Calcium:Magnesium at a 4:2:1 ratio as a starting point. Most plants will enjoy this. Some may require tweaking.

Otherwise they mess with eachothers absorption.

Look up Mulders Chart. It shows every nutrients protagonist and antagonist in terms of nutrient absorption

Mulder’s Chart of Plant Nutrient Interactions | Permaculture Noosa

permaculturenoosa.com.au permaculturenoosa.com.au

How the arrows work is if its pointing towards a nutrient it affects that nutrient. Some nutrients effect each other in both directions. Like Potassium and Magnesium for instance. As you can see Calcium affects the uptake of 7 different nutrients.

Ty.
So i was feeding gh flora 3 part per chart. Plus some hydroguard.
Then i switched to lucas ratio. 40 ml micro 80 ml bloom. And i also bumped,that up,to 50. 100. But this was already developing...

Im in a quasi aero setup. I guess i should flush immediately and get a good look at my roots....???
