Help with hydro grow

A question from a fellow grower:

I recieved my order from you
guys about a month ago and I must say that I am pleased, but I am a
beginner and my flowers aren’t coming out quite right. They’re about 4
or 5 inches tall and I planted them on 4/28/15. I was told that they’re
supposed to be at least one foot tall after a month of being planted. I
need help because my leaves are turning yellow and they’re growing slow.
Also when I add the correct amount of nutrients my pH balance drops…
Is it the lighting thats cause my leaves to burn? I have the light
about 2 feet or so above my flowers…

Let’s get you started with a ILGM support ticket that Latewood had first developed. It’s is a great checklist of things in your plant’s environment that might help give us an idea of what could be going wrong.

Answer all the relevant questions the best you can, if you do not know, or do not use something, just say so or put ‘NA’.

ILGM Support Ticket:

What is the strain and type(strain name, unknown bag seed, regular seeds, feminized seeds, auto-flower, etc)?

Indoor or Outdoor? If outdoor, planted in ground or in a container?

Size of space (max height and area, length/width)?

Soil or Hydro? Type of Medium used? System type?

pH? Of the soil or medium (root zone/reservoir/runoff) and of the water and/or nutrient mix that is fed to the plant?

Type and strength of nutrients used? NPK? EC/TDS/PPM levels?

Temperature? Day vs. night temp or highest and lowest temps? Root zone temps?

Humidity %?

Light system/watts/lumens/FLUX/PAR?

Ventilation system? Size? CFM? CO2? AC, Humidifier, De-humidifier?

Number “weeks/days” from into Season, Vegetative Growth or Bloom/flowering?
