Hmmm, I wonder why you are adding cal-mag unless you read it somewhere to do that, when only using the Tiger Bloom(it has all kinds of metals and minerals in it). I use the FF TRIO pack for my feedings, so I get all my cal-mag requirements from their solutions. I would flush with water for a couple of weeks then use a 50% solution of their Big Bloom(organic), with 50% Tiger Bloom. This is just a suggestion and not to force you to buy another product.

Deficiency/Light Stress Issues What else can I do? Brown curled tips and spots on older fan leaves climbing up towards main cola. Flushed with pH’d RO yesterday, but was only able to get pH to 6.7, also added small dose CalMag at end of flush. Light wattage has also been reduced by half for the last week.

Can someone tell me what is this? I think the reason is that my nutrients are not balanced but I have no clue what deficiency this is, It could be so much easier to know the reason for this if I know what this is. pH pretty stable 5.8 Ec 1.5. Thanks!

Flush or what to do ?Advice please. I watered yesterday but the stains on the leaves are getting worse. Now I don't know if it is deficiency of cal n mag due to nutritient lock out which might be due to ph being off as I have 5 reders and all of them show a different thing. 🤦‍♀️...or it is it rust?

What nutrient deficiency is this?What nutrient deficiency is this? Or is it nutrient burn? I'm watering with 5.5 PH using half strength Nutes, Root booster & Calmag. I don't think it relates to spiders mites since I can't see any with my 30x magnifier. Thank you so much in advance.

Too much light or other deficiency Too much light or some other deficiency? I’ve been having some issues with yellowing leaves and some other issues with browning and wilting/curling which I thought was initially nutrient lock but what I noticed is all four plants were not stunted and continued to grow normally.

Yellowing and brown spots on leaves Can anyone identify why this is happening? I am growing 2 other plants (one the same strain) with identical treatment and this started happening with one of my Royal Jacks. Everyday new leafs show the same symptoms.
