Nutrient Help possibly neededFor my first grow I have kept things fairly simple. I had issues with my soil PH which stopped nutrient uptake but seems to have now resolved that for the most part. Are there any other nutes that are recommended to help bud production or am I ok with what I have now? ThanksWeek 8

Yellow leaves from bottom upwardsI have yellowing leaves from the bottom up. It resembles either N deficiency, MG deficiency or both.
Growing in soil.
PH is between 6.5-6.8.
Feeding 1ml/L fish mix and 3ml/L bio-bloom every other watering.
I tried adding cal-mag with N at 1ml/L and if anything it's got worse.5y ago

Cal-mag deficiency?Hi guys, I think it's magnesium deficiency (early flowering). I have also noticed a few small burnt spots on the leaves. Is this time for cal-mag? Or am I reading this wrong?Leaves. Color - Pale

Drainage issueI'm not quite sure why this cup doesn't absorb its waterings when the other two solo cups are getting Watered every day. All 3 cups have no drainage. They are all grown in the same conditions.
My first instinct is lack of drainage, do I need to make some holes, bottom or side?Week 5

Deficiency?? Excess? Neither?Grown this strain before and had the same issue.. not sure if its a CalMag deficiency entirely. pH has remained at 6.0-6.5 or so in soil and didnt show signs until recently, seemed to have worsened after just two days of only CalMag and Ro water so I bumped up the bloom nutes.4y ago
