started grow question 6y ago
What can this be? It happened in 1 day. Is plant asking for nuts? I added only water for 4 days because i was afraid of been giving to much nutrients. Could be a pH problem?

Slight lightburn?
First pair leaves on left plant turn slightly lighter, first sign of yellowing a bit. Also I think they are a bit in a V/praying shape. 2 full weeks old under 75% of 200W leds about +-45cm. Should I dim them a bit more/hang higher? Other suggestions maybe?

Yellowing new growth.Normal or should i be doing something?
Might be an overreaction but i am noticing all my new growth is yellowing. Could it be a high/low temp fluctuation imbalance during the night/day cycle? Is it a problem? Should i be doing something to fix it? Im 2 days into flower.

Why are my leaf tips getting bleached still? I have the light 18 inches from the canopy which is what is recommended for veg, and that's only around 400umol/m2s but the leaf tips keep burning. Temps are low if anything, consistently between 65 and 75 farenheight.

Yellow spots nute difficiency? Light burn?
I noticed spots on both LB and NL that seem look like nute deficiency, my best guess is cal. I will check pH of soil runoff at next watering to eliminate lockout as a possibility. I've heard FFOF soil runs out in about 4 weeks, maybe that? Light burn from water drops on leaves?

A deficiency, a toxicity and a toxic-deficiency???
Here's what I make of it (and PLEASE correct me where I am wrong!) : The tips yellowing indicates, a nitrogen burn. The burnt brown tip indicates, nitrogen burned to long 😂 The black spots indicate, a P or K issue (as the leaves are otherwise healthy green in color)
