Deficiency Noobs!! READ FIRST.
i read soo many problems that all relate to the same thing!!
Which is nute lockout/deficiencies. Now any plant food worth its space on a hydro shelf will have everything your plant needs. So when u have these 'deficiencies' showing up, its rare that the plant is deficient of the nutrient, its that its not able to take it up properly..
Which is caused by:
Over-feeding, thus causing lock-outs and
Incorrect pH thus causing lock-outs and deficiencies
STOP overfeeding ur plants and trying to push them soo hard!
STOP lowering ur lights, i dont care if ur hand isnt burning under the light, be kind and just back it off
STOP adding adding adding when u have a problem, back off..and work backwards (see below)
So to conclude, if u got a problem, and ur too inexperienced to know wot it is:
*Flush
*Re-nute @ lower ppm with pH'd water
*back the lights off
Then when ur dialled in and ur plants are flying u can start to push them along ie; begin to lower the lights, begin upping nutes, squeeze ur nipples etc etc etc...
and
PLEASE the time to read and understand the pH table, its quiet simple,.. it shows how ur pH must be right in order for the plant to take up the nute
