i got some white widows that are about a month old from seed (not clones) and the ppm is currently at about 750ppm which i thought seems high for only being about a month old but they seem to be doing great no nute burn whats so ever. so is this about where my ppm should be should i go higher since they look good?
also can someone give me a guide to what ppm i should be at and at what stage. for example like what should my ppm be at in the next few weeks what should it be at when i start to flower etc.
