Burning from over feeding. Nothing to do with calcium. 18/6 is best for cannabis, they NEED sleep.

Nute Deficiency or New Leaves?!
Thoughts if this yellowing may be nute deficiency? Or are these just new leaves and I am concerned about nothing and I’m babying them since it’s my 1st grow? Both plants are about to be 2 weeks post sprout. Both are in 5 gallon fabric pots with layered soil (FFHF on top of FFOF)

Pin the tail on the deficiency
Some yellowing that developed on Gelato Auto in the last coupla days....my guess is nitrogen deficiency since feeding has been light throughout growth but I'm still new to the game and would love to hear from some more seasoned growers

Why my plant is in shock i fixed the ph of watering .I suspect of this reasons:Heat wave/changing phase to flowering / nutrient locked/ over watering/. In
I lowered the ph of watering from 6.8 to 6.0 but this plant is still is shock and wont grow like others. Could it be a sign of changing phase from veg to bloom ? 3 weeks ago my first plant went to flowering and did the same color fading. Now that plant has good color
