Not light stress, but the beginning of magnesium deficiency. Giving cal/mag will solve this and prevent it from getting too much worse.

BT21 Probleme?
Hallo liebe Grower, bei mir ist BT 21. Kann mir jemand sagen warum die Blätter der Blütenstände so „Neongrün“ werden ? Liegt es an Nährstoffen oder zu viel Beleuchtung? Die Lampe ist recht nah dran da keine Luft mehr nach oben ist Wäre super wenn jemand einen Tipp für mich hätte

turned yellow, what's the problem?
The big burdock at the root started to turn yellow a couple of days ago, the tip is drying and bending. This is a deficiency of phosphorus and potassium on the 45th day from the nut (7th week) - or am I wrong? How to fix it?

regarding the light spectrum ratio. what is the ideal light spectrum for both the vegetative and flowering phases? Do you use 3500K lights during the vegetative stage, or only use cold white lights at 6000K? do you then switch in flower to 3500K lights along with 370-780nm?

Yellowing and lightening of leaves
My back-left plant started to slightly yellow on me from the bottom up. Front-left is also lighter than the rest. Is this a feeding issue? Do they need more nitrogen or did I overwater them? Appreciate your answers :)

CalMag or PK issue?
What is she telling me? Before I was thinking of a CalMag issue (upper leafs have "burned" tips and get yellowish). So I added it to the reservoir. Is it CalMag or maybe a PK issue, that resolves in a CalMag issue? See my diary for more details.

Burn or ?

Will increasing light intensity restart stalled seedlings
Seeking advice from Mars Hydro TS1000 growers. When do you increase light intensity during seedling stage? I've had the light 30cm above the plant at 25% power since germination. The plants stalled 2 weeks ago. Can I get them going again by raising intensity or will I fry them?

Fatal ovewatering? Will she survive?
Ugh! One of my two plants Is dying. I suspect overwatering associated with some other issue I can't spot properly. 58 days flowering. It was my first flushing session, not a good start. Her sister has no problem. Poked holes in the dirt, raised temp, maxed the fans. What else?
