Harlequin (Fallponic RDWC)

WEEK 14 - 23/10/2021 - 29/10/2021 27/10/21 - Leaves on plant 2 and 3 especially seem droopy and clawing in. I've been noticing this since last week. Also they are dark green. There could also be micronutrient deficiency like manganese. I'm thinking nitrogen toxicity leading to micronutrient lockout. I should have taken out Gro from last week's res mix. I'll be doing a complete nutrient res change tomorrow and hope the symptoms would improve. 28/10/2021 - Complete res change done. 30 gallons of water mixed with the following: Liquid Silicon - 1ml/gal - 30ml Cal-Mag - 2.5ml/gal - 75ml Micro - 4ml/gal - 120ml Bloom - 7ml/gal - 210ml Hydroguard - 2ml/gal - 60ml pH - 6.12 EC - 1.21 mS/cm T - 24.0 The buds are getting thicker and trichomes are more prominent. Defoliated most of the clawed leaves.
