PH & lockout?

[Merkle420]

Shiva shanti2
Grown in soil
Nurses aren't the problem
Temps between 25-29
Rh is low 20-40 but I'm trying to change that
They take a few days to use up the water I give them.
Leaves are purplish some going yellow stunted growth
Still seedlings
Don't know what's going on my feed ph is always around 6.3-6.8
And run off is around 7-7.2 that's too high isn't it?

re: PH & lockout?

soil likes slightly acidic or 6.5
try for a little lower max daytime temp by moving more air or exhausting more

what kind of soil? true dirt? or soiless mix?

are you feeding everytime you water? if so how strong of nutrient solution?

it sounds like your soil is very alkaline. try doing a soil slurry test with ph 7 tap water and seeing if after being run through the soil the water is gaining alkalinity.
can be done with a probe ph test easily or run the slurry through a coffee filter and test the strained slurry ph.

if high ph buy a flush product and flush using the recommended dose for soilless mixes to get rid of salt buildup or water with ph'd water with 1/4 strength nutrients until 10-20% runoff to wash old nutrients.
