how to beat Fe or iron def??

wats a way to beat the symptoms of Fe or better known as Iron def?? im lost an i read so much im confused now darnitttttttttt!!!!!!!! i have ffof nutes an soil eveything gets phd and im usin the ff schedule from there website its only doing it to 2 plants outta 8 same strain...... wat is cal-mag used for?? and usable in soil??

Buy dolomite lime for soil for cal/mag. Why would you think the plant is iron deficient? Pics help and help prevent misinformation or bad advice.

hey thanks im at work rite now but the flowers and new growth is yellowing from the stems out in these 2 plants and there in there 1st week of flower seems total opposite of all the other plants......................... pics late tonight sry bout that but the pictures are exact as my leaves

not trying to sound like a douche here, but usually the cure for any sort of deficiency is the element that it's missing..

ie, the cure for iron deficiency is iron, the cure of cal def. is cal, etc, etc...

pix would help narrow it down though..

sry im at work and on my phone atm its hard to do this but heres acopy of problems - Marijuana plants suffering from deficiencies exhibit yellowing of new growth.- Marijuana leaves on growing shoots ARE yellowish an the outside of leaves still adark green.

so how would i fix the prob usin the ff nutes safetly wat bottle to use im just lost cuz there all fed evenly at same time

the only iron and sulfar is ff open sesame any suggestions

heres some photos

Dolomite lime and "Ironite" are both available at Lowes or HD. Cheap too.

Any decent fertilizer should contain iron. Even Miracle Gro does.

As a matter of practice, cannabis likes Ca and Mg, and these two in practice are the most common trace element deficiencies.

I'll make the following suggestion.

Instead of trying to guess which exact nutrient deficiency you plant has (where there is a good chance you're wrong), just add a good balanced fertilizer appropriately to take care of ALL possible nute deficiencies at once.

im usin ff nutes and schedule any suggestions ????? and im looking into epson salt right now any info??
