Too much nitrogen (nitrogen claw) What nutes are you using ? Want pH & Ec are you feeding ? How often are you water/feeding ?

Ph in the water i give it is about 7.8.. I’ve only fed it once last week with Cana A@B and used half of the stated amount when I mixed it because I read the soil should be enough to feed it In the first 6 weeks of growth, it’s in a hesian pot.

Coco & perlite are inert they contains no nutrients...The pH of the feed solution for coco should be around 5.8...There is no such thing as the stated amount with this method of growing the plants will require a specific Ec (feed strength) dependant on size and stage of growth...

Understand now I’ve thought it through, because it’s growing in 70% decent soil and 30% coco (to help with oxygen/drainage) my theory was to halve the A@B normally for 100% coco to compensate for the 30% nutrients missing out of the coco and I think I’ve essentially over fed it , am I on the right lines ?
