    Default Nutes def, light burn or both?

    2 x autos (WW & Lime from DP)
    2 x 11 lt softpots
    Coco coir
    80 x 80 growtent
    DIY led panel: 16 x 20 watt E27 (now @ 2700 & 3000 lmn)
    Chino panel (Bestva 300)
    Total: 400 watt lights
    Distance from top bud 40cm
    Climate control, air circulation, etc.
    Current temp: 25 C
    Current humidity: 45%

    Germination Apr. 20
    Flushed at day 45
    Current feed per lt:
    - GHE Flora Micro-Gro-Bloom at 1/2 of official feed schedule (0.5ml-0.3ml-0.6ml)
    - Rhizotonic 0.5ml
    - Silicon vitalink 0.5ml
    - Cal-Mag Pro Ionic 0.5ml
    Filtered water
    Feed schedule: every 2 days ~ 4 lt each
    Ph feed 5.7 - 5.9
    Ph runoff 6.0 - 6.2
    EC feed / runoff 1200 - 1400


    10-12 ago a few top big fan leaves at the main colas (under the center section of the led panel) started to turn light green between the veins. I didn't pay much attention as the plants generally looked happy. Gradually, the discolouring extended to more top leaves, and now there are several yellowish big top leaves at both plants.

    3-4 days ago I thought it was some kind of defficiency (nitrogen / magnesium / iron) and I upped the CalMag and the Micro-Bloom dosage. Did not see any particular improvement, so I pulled up the ligths at 60cm from the top buds. Still no clear sign of recovery.

    Any ideas?

    They are just lacking nitrogen mate. I would remove rhizotonic,cal-mag and the silicone from feed and carry on on base nutes only and PK until flush. As they autos I assume they won't be far from flip so just do that and flush when you happy with trichomes..

    Thanks mate.

    I reckon I am about 2-3 weeks from chop, could it just be normal nitrogen consumption from the buds or is it too early for the plants to start consuming their own resources?
