Help identifying deficiency
DreamCatcheranswered grow question 4 years ago
If it happens on the lower/older leaves at the bottom of the plant and crawling upwards then its a nitrogen deficiency yes, but looking at it it has discoloration between the veins which makes me think it might be a calmag imbalance. Looking very good though ^_^

Looks like nitrogen to me. Boron usually has really twisted new growth on top of the color. Iron can sometimes look like it if your PH is off.

Veg Nute IssuesHas anyone seen any diaries that catalog a successful sick veg -> healthy flower recovery? I'm curious to see how sick growth transitions to healthy growth over several weeks. Current issue: a) LED intensity, b), N excess, c) PK def, or d) cal/mag def(rust on leaves top and btm)?

Nute deficiency?Unsure what could be going on here so hoping some wiser heads could see me right as this is my first
My waters pH is on the high side (Just shy of 7). I fed around 150ml of water with 0.15 of Bio-Grow 3 days ago and since have been keeping the medium moist.
Advice is appreciated

General healthAdvice please just on wether it's looking healthy. :)
I've been too careful with watering and some leaves turned yellow. Feeding 1 litre every other day but maybe that's too little? Stopped with the Biobiz fish and switch to growbloom. Leaves at the top look droopy still?

Issues after first sledgehammer flush, 4 weeksHey guys and gals, on week 4 of this indoor, hydro grow and I just hit this plant 5 days ago with fox farms sledgehammer for its first flush. Before this, the plant was growing very well. Is this due to the flush? Should I flush in tap water before next feed? Thx for the help ^^
