Hey all,
im growing in coco, ive watered my girls, with 1.0EC and PH 5.8 and they seem a bit yellow on tops, ive used

Roots Excelurator
Calmag
Bio essentials
Pro Silicate
There are some pics
Lets see what happens with this girls.

I may treat for a N def if it was me yes

Its not nitrogen deficient. Nitrogen def shows up in older bottum leaves first. Beings how you're in coco it could be the first signs of a magnesium deficiency. Make sure your pH is in range, could be sulfur or iron def as well.

Not yet. if you think that - maybe you should reduce your nutrient amounts - consider reducing your base nutrients when using Cal-mag (look at all the "N" you are giving the plant in relation to all your listed nutrients)

Epsom salts will treat mag and sulfur, although its probably not a sulfur deficiency. More than likely magnesium because coco holds onto magnesium. An iron deficiency would more than likely be caused by pH being too high.

Epsom is Magnesium Sulfate only.
IRON [FE]
SYMPTOMS:
Marijuana leaves on growing shoots turn pale and veins remain dark green.
( Most importantly pH imbalances make iron insoluble.)

your plants are fine, they re immature so can only take up so much nutes, but you have no defs, and u r pH ing correctly so alls good, only thing u may wish to consider is airstones in the nute solutionso the leaves don't droop so much but no biggie
