info on these spots?

what the hell are they? is it a calcium deficiency?

I think the spots with a brown center are the Magnesium and the yellow spotting is the Calcium.

I use foliage spray with a wetting agent to correct this stuff in the young ones. If I try with feed, I will always over water.



Needs Mag



Needs Calcium


Here is a problem solver I use sometimes.

Check your PH that's a common problem with Ph fluctuations locking out nutrients.

I would tend to lean towards a Cal-Mag supplement as it does have that look of deficiency

It would really help if you gave us a bit more info rather than just a pic of leaves, as without knowing your medium and growing conditions, we can only give you a wild ass guess.

that is true sorry it is in foxfarm ocean forest. 400 watt Mh bulb currently running it on 75% power. fox farm nutes, but i just started nutes this week. i only gave it a half tea spoon of growbig its first nute feeding. its 3 weeks and a couple days old. but it had some of these spot before i gave it any nutes. hope this helps some more

Mag deficiency caused by inproper pH. Stop using tap water.

no where did i say i used tap water. i use distilled water? and i check the ph before i water it is always between 6.2-6.5

Hmmm odd, usually people who mag deficiencies are using tap water. A 6.2-6.5 pH wouldn't necessarily cause a nutrient lockout in soil. Problem might be something else. Possibly the early stages of a fungus of some sort similar to leaf septoria.

it could be the ph of my soil. i lost my soil ph test. just had to wait for my paycheck this week to grab a new one. it also looks more like the example of a cal deficiency

it sounds like i just need to buy some botanicare cal-mag and it will solve this problem lol

I usually add dolomite lime with FFOF. I find that Cal-Mag is the only really missing link to Fox Farms line up.

Magnesium deficiency for sure... Add cal mag. Not sure why the nutrient mfgers don't tell you that you need these macronutes that are not usually included in 2 part formulas. Had same issue way back when...tap waters not an issue
