Mag Or Iron Deficiency..what say you?

You don't need to make drastic PH adjustments, just adjust your nutrient solution to 5.8 and feed to plenty of runoff.

Quick Update: Surry Test = 6.9 pH.. what does that mean?

I add iron to the initial soaking water on the FFHF. I use to use outright pulverized rust but went to Fast Acting Iron by Encap. Got it at Menards.

I'll look that up, thanks. Hydroponics Cal Mag solution does have Iron in it, I just don't use it as often as I should maybe, Once a week might not be enough, these ladies might be growing faster than I think they are. Have no idea, first grow. I topped it this morning with 6 cups of the solution just in case. the soil is still wet from Sundays watering. Not supposed to water them till Thursday, let the water evaporate some so not to drown the roots.

The iron is just a one time deal. Same with the limestone. Some limestone has iron in it if it's orange, brown or yellow.

The Iron supplement gets in today, anxious to see how the ladies respond to it. Will do half recommended dosage. Of all the ladies ...one is unfazed! The only difference between that one and the rest is it's not as mature in flower as the rest, so yeah, the more mature flowers are clearly crying for a missing nute that their not getting as much of.

Iron will help the yellow one green up I bet. It should turn the green one darker green.

and possibly This--->

CAUSE: OVERFERTILISATION

"A heavy-handed approach to nutrients is ill-advised. Excessive doses of nitrogen-rich vegetative growth base nutes can cause clawing in leaves. Sometimes, they will even canoe. Similarly, overdoing it with the phosphorus and potassium during flowering will cause curly cannabis leaves and scorch the tips. Chlorosis is a common symptom in both cases."

EXACTLY what I'm going through ...

Apparently Sativa strains are more sensitive to overfeeding than the Indicas? . Who Knew?
