Nutrient burn, Light burn, or Phos Def? red stems purple bruises,
Noticed red lines leaking red into the leaves with purple bruising, and the starter bottom leaves seem to be turning yellow, with the leaves above looking dark green with spots. Is this signs of light burn or nutrient toxicity? And is it lacking phosphorus or just the strain gen?

Growing out instead of up.
Please help out! I moved it into a new pot and topped it last week as suggested. Also new ViparSpectra light at 45cm away @80% power. Nutrients/food yet to arrive. It seems to just be growing out instead of up, and starting to see some white/ burnt looking spots. Suggestions?

Yellowing leafs and dying tips
Hello ! In the last few days I founded that some leaf started to yellowing and burning on the tips . Maybe it's all due to the flowering stage but I'll be more calm with your answers that are always interesting and helpful even if the platform allows only one to be selected.

Yellowing plant
Why is my plant yellow? I thought nitrogen or magnesium or PH. But i tested everything and it is still yellow. I tried flushing and using no nutrients but didnt help. PH is good, tried giving extra nitrogen and magnesium. What else can it be?

Light height and intensity
Hello all. Recently I upgraded my lights to 2 mars tsw 2000. I've noticed my plants are growing slowly compared to everyone else's. I have it set at 24 inches 25%. However a mars hydro admin posted 12 inches 75% during veg? Isn't that like 1500 ppfd? I'm so confused.

Do I have an Iron Deficiency, if so How do I increase Iron levels (Already using Calmag)
I think I have an iron deficiency. New Growth is appearing yellow. HYDRO Rain water - (20ppm) PPM 750-900 (just upped) Canna Aqua A+B Calmag (0.35ml/L) PH was 6.2 (as there was a calcium deficiency so I raised it slightly) PH is now 5.8 (I read lower PH is better for Iron Intake

Yellow Cotyledons?
NLxBB was born with yellow cotyledons. The shell was stuck after sprouting so I had to help remove it. Took around 2 days before I saw them barely open with new growth. The new growth is green and seems healthy. Is there any reason why this is happening?
