My plants are 5 weeks into VEG.

Hydro
Rockwool Cubes
Botanicare Nutes


The leaves are slowly dying off and yellowing on the bottom of the plants.. Kinda working its way up..

Is this normal?

Would it be from Overfeeding? Or underfeeding?

I am still not @ full strength nutes..

sounds like a nitrogen def, what are the npk of your nutrients?

Would it be from not being @ full strength yet?

What is NPK?

.. the 3 main nutrients n-p-k nitrogen phosphurus potassium usually a label like
2-1-2 on the front or back of the package.

and it could very possibley be from not being at full strength depending on your npk ratio of your nutrient. hydro can be very tricky if your new and don't have the right tools to measure your ppm and ph. you also should be changing the water and cleaning the tank every 7-12 days

If you don't know the npk, you shouldn't be doing hydro yet. you'll run into a lot of problems and now know how to fix them, or where to start.

I have a PPM and PH meter..

Sorry I didn't know what NPK meant.. But I do know everything else..

I am using Botanicare's Pro Grow Blend,and Liquid Karma..

Nutes:

Pure Blend Pro Grow 3-1.5-4 Vegetative Formula -

Premium organic Plant Food

15 ML PER GALLON FOR MID-SIZE PLANTS - 30 ML PER GALLON FOR MATURE?

Liquid Karma .1-.1-.5 Biological Plant Growth Catalyst -

10 ML PER GALLON

I have just mixed to full strength for 30 Gallons of water, with 30 of water.. I Didn't add the Liquid Karma, just the Pro Grow and my PPM is already 1402 and PH 5.6..

Is PPM too high? Should I dillute with water? Or what do you recommend?
