Hi all
I've got two mother plants approx 5 moths old under an 8 tube T5 flourescent throwing out 38000 lumens both in 11 litre pots.My cheese mother looks great but my AK47 mothers leaves have gone bright green and have red woody stems and some leaves have slight redness at their very edge.They're both in Biobizz Allmix as a growing medium and I've been feeding them Biobizz Biogrow NPK 4.0-3.0-6.0. plus 1ml per litre of Canna Mono macro nutrients.I'm thinking it's a nitrogen deficiency so I'm foliar feeding them with Nitrozyme every other day but the AK doesn't seem to be responding.Anyone got any suggestions other than a nitrogen def or am I going down the right road just being a little impatient.
