Grow Mediums Switching to flowering nutes confusion.......

[FadedMalone]

I'm growing in 1 gallon hempy buckets and am at seven weeks on Dinafem roadrunner and am ready to switch nutes to bloom. I'm using GH flora three part and kool bloom. My question is should I even use kool bloom and when I mix my nutes should I stop using grow and use more micro and bloom or still use all three? Bare with me i'm still learning guys...

I would use the Kool Bloom in conjunction with the Flora 3 part. It's a bloom booster, NPK of 0-10-10. I've used the Flora myself and always use a bloom booster along with it. Some strains do show P and K deficiencies in mid to late flowering on the Flora alone and the Kool Bloom will address that.

I think I used to much kool bloom on one plant at 1/2 tsp and think I caused a iron def as well. I want to be careful on the next two.

I doubt that little amount would cause an iron deficiency, especially from only one feeding. If you're seeing a light green/yellow color on the leaves with dark green veins, I'd look more to magnesium. Iron and mag issues can look very similar and mag deficiencies are common where iron is rare. Many auto strains show cal/mag deficiencies around the end of veg, beginning of bloom. Always a good idea to keep a cal/mag supplement on hand just in case. If you're using RO or distilled water, a cal/mag supplement is a must to replenish the trace minerals that RO and distilling remove.

I've been giving cal-mag at a 1/2 tsp in a quart of water. My pots are a gallon and a quart feeds them but they drink a quart or more a day. I won't be doing gallon hempy buckets again. My PH has been good and the problem showed up over night. I actually thought it was light bleaching cause I added a new 180 watt led but since took that light out and continued with the led I've been using. Maybe I stressed the plant a little or something?

Post up a couple of pictures so we can see what's going on. A close up as well as a full plant picture. Light bleaching will show on the uppermost leaves starting at the center of the leaf and working outward towards the tip and edges. Everything, including the veins, will be a yellow/white color.

here are a couple pics. The first the whole plant,the top and mid branches.

 

[Muddy]

No, not light bleaching. I'm more inclined to think it's magnesium. Try giving them a foliar spray of 1 teaspoon epsom salts to a quart of water. Do that once a day for 2-3 days. However, if you see that yellowing start to turn white, let me know. That would indicate that it is indeed an iron issue.

Will do and thanks for all the help Muddy..
