Orange marks on leaves

I have two THC Bomb plants with orange strips or spots. I can't seem to find a pic that can tell me what caused them on upper leaves. Plants under 600 watt HPS and both plants look really healthy and bushy.

Anyone seen this on leaves before?

You have either a deficiency or if you are foliar feeding it'll be water burn. They are called rust spots and you normally get rust spots with a few deffs. What do the tips of the leaf look like and is it near the bottom or top of the plant

I don't foliar feed but did hit plants with some SM-90 twice when I had two days of humidity above 70%. I have no problems with leaf tips except is got a little nitrogen deficiency, but it worked its way out without much leaf damage. The two plants that have these spots, are my strongest and biggest plants. Very health except a couple rust spots. I'll keep a eye on both plants to see if more appear. I just feed them yesterday so I should know soon if more rust spots appear or it gets worse.
 
Copper deff is usually caused by PH not allowing it to be available even though it's in your medium. Check your PH if it's not that the u can rule it out
 
can you get some pics with the hps off and use a couple of cfl's. also a pic of the whole plant.

i use the foxfarm line and have found better results by adding MagiCal.

Sure, the first 2 pics are the plants with rust marks. The other 4 pics are my other medical plants. The 3rd pic is my Big Blue Cheese plant. That plant has been the one with most issues. It had some burns from Nitrogen toxicity and shown def in magnisium. I feed it a full dose of general organics Cal-Mag. Should regularly give all my plants that and how often?
Plants in order

I normally use 1/2 tsp of MagiCal per gallon of water or in a gallon of nute mix. I use it in just about every watering or feeding unless the plant doesn't need it. Some plants can get away with every other watering and other plants want it ever watering.

I dont use MagiCal during the seedling stage or the last week of flowering.

i am not sure if what you have is a calcium def. but i have not had much for rust spots since using the Magical.
 
I've always had problems with THC bomb . rust spots looking like cal mag def heat stress pH problems, I've slowly moved it out of my garden just finishing my last run with them. Every time
2-3 weeks in the top leaves would start to lighten with brown spots then leaves curl up turn yellow crisp and die off. Supplement cal mag tried changing nutes still couldnt figure it out. Hope it all works out for you ive seen lots of good reviews on THC bomb just didn't work out for me
 
Sounds like you need cal-mag, I grow a cross of thc x white russian they did the same thing
to me first grow added cal-mag and no problem.
Also what size pot do you use? thc bomb grows some huge root balls you could have a
problem with circle root.

I'll start using it regularly. I usually give it every three weeks of flower, but by end at harvest, leaves are a little depleted

I finished a THC Bomb last grow and got over 4 oz and it looked healthier than my white Widow. I guess I could have been lucky though
 
You should get a lot more from the bomb try giving every week with good high PK low
N nutes. you will see a large difference. That's for any weed.
Keep it green and growing.

That's the opposite for me now my white widow looks amazing next to the THC . great yield, solid buds they harden up lots at the end if you let them go a little longer
