Hey all I've been switching all my food over to Jack's 321 . Media is promix . Feeding at 1100 ppm ph 6.3 . Run offs are 800 ish and 6.1-6.2 ph temps are pretty constant at 78 during the day and 75 when they are sleeping . Humidity is 50-60 percent . 1000 w HP's fixtures in this room . Veg has been amazing but this time around the plants are yellowing . I've looked at alot of deficiency charts but not seeing a exact match . The yellow viens in the leafs stand out to me .. thinking sulphur deficiency for that . But also has a magnuisium deficiency look . Any ideas out there? Thx in advance

if nutes are on point and you are fertigating enough times per day and your PH is good then you have a root problem lock out problem

Jack's 3/2 for veg. 3.6/2.4 for flower. Add magnesium sulfate if you are under LED or see a deficiency.

The only way people have deficiencies is when they try to tweak the recipe or have too many variables.
