Looks like a possible deficency crawling in. She's looking light in color also. Try feeding with a higher nutrient dose. 🤘😤

Lighter green leaves
Day 11 bloom. Growth has been slowish I think due to compact soil, maybe PH issue. Using biotabs and light biobizz. Since switch, the leaves have turned much lighter green with few leave edges turning yellowish and can see more veins. Is this a feeding issue or other indication?

To solve the problem of leaves, we did not notice any difference with an ec of 0.8 and 1.4. (group separated 2 weeks ago) :/ Any propositions? In hydroponics is it common for you to use power roots, green sensation, cannazym or the hydro A&B product really enough? Thank's

Why do I have rapidly spreading yellow on my leaves?
I have this yellow spreading on some of the larger leaves and it's moving super fast. Please help. I've done research and it says it's a deficiency, mostly likely cal/mag. I added that and it got worse, now I'm thinking nutrient lockout? The pH is fine. What do?!

Purpling, contorting, drying, yellowing.
Leaves are going all nuts, i think it was from a bad feeding, i've been too busy, no time for notes, they started going purple after feeding so i used plain water for the next 3 waterings with +water, tops started showing calcium lack, anyone can confirm? Give bloom+cal right?thx

Defoliate yellow leaves?
Should we remove these large yellow crusty leaves near the soil? The plants are at about day 38. I've heard people say you shouldn't defoliate this early in flower. Should I be concerned about these leaves dying off or is this normal?

Gelbe Verfärbungen der Blätter
Ich habe komische gelbliche Verfärbungen (quasi Camouflage) an den Blättern einer meiner Pflanzen entdeckt. Es ist aktuell leider sehr heiß im Zelt mit bis zu 30°C, ansonsten habe ich wie schon den gesamten Grow nach BioBizz Düngeschema gegossen. Aktuell: Temp. 28.9°C RH 35%-42%
