Yellow from bottom up means they are deficient they need more nutes specifically nitrogen and calmag.
Don't over water, but increase the amount of nutes given.
They will bounce back...
Always check runoff ppms.
If it's 300 or more MORE then your input ppms you have a toxicity and leading to lockout.
If it's 250 or more LESS then your input then your deficient and need to increase nutes.
Goodluck and feed more!
