Hello Everyone,
I need a bit of help here first I'll explain my setup and then the problem I'm experiencing.
The setup
I'm growing a two shelf closet scrog 2 shelves - 4ft x 3ft x 5ft (LxDxH)
2 x 600w hps cool tubes
Biobizz Light mix soil
CO2 gas system outputting for 15 mins every hour (not completely air tight so have it turned up to 75m3)
humidifier running 24x7 keeping the humidity between 40 and 60
Heater runs at night keeping a temperature of 82* and daytime temps are 89
good air circulation in the closet.
The Nutrients
Biobizz range
Fishmix
Alg-a-mic
Bloom
Topmax
Seaweed solution
Tap water left stood for 24hrs temperature around 24*
The grow so far
Veg time - 4 weeks, dosing water with 2ml fish mix and 1ml of the others (except seaweed)
I have followed a feed / feed / water routine.
Feeding every 2-3 days when pots are light
Switched to 12/12 two weeks ago, pistils looking good
The problem
Ok so they grew very well in veg with one plant looking a bit yellow all over.
With not wanting to over-react I let them all dry out and fed with water to see how it recovered.
The one that looked yellow started to recover a few of the others seemed to be starting to go the same way.
I suspected a N deficiency so I upped the nutes to 3ml per liter as I had veged for longer than the Bio-Bizz chart.
Unfortunately no change.
I have good control over environment so I don't think it's a temp lockout, PH is questionable although its just some of the plants, the rest all look really healthy.
I'm tempted to try a fish mix folier spray 1ml / litre but two weeks into flower I'm not sure if I should.
Any advise much appreciated.
