runoff PPM extremely high.

noobiiistarted grow question 4 years ago

So, I am using tap water and its ppm is between 300-400. However I just checked by runoff water PPM and it came over 2500 with ph around 6. I have not used any fertilizer whatsoever and the soil is BioBizz Ligth Mix. What could be causing this issue?

Organomananswered grow question 4 years ago

If your plant is growing well, is there a real problem? Your high readings are probably from the fertilizers the manufacturer added to their soil mix.

Your substrate (soil) will have nutrients already. You do not really need to add anymore at this stage.

PK13/14 or Coconut water?I am getting ready to give the girls a blast of PK. They are all going into week 5 of flower soon. Please see my diary. Should I give CANNA PK13/14, or can I achieve similar results by adding coconut water to my bat tea? Thanks The Mac

Half eaten plant What do y'all think is eating my plant? There's 56 out here and only the one is getting ate up🤷🤦. It's big enough to break branches. No deer around here like that I'm not close to any woods that they would come from without being seen....the plants growing great besides that.

Flowering or still vegetative? Food question too don't know whether is considered flowering or not. Pistils are out, no other bud formation. Should I feed my plants same food as last week or just give ph water and calmag? I don't know if i jumped the gun last week. Promix hp cc is medium, and they only get fed when dry.
