Temp is 75 to 77 And the humidity is 40 to 50% im looking for a better humidifier right now one with a larger tank also. I'm using the same exact nutes your using I've been giving them 1/4 strength today was the second time I've gave them nutes. Like I said I gave less cal-mag then I should of. Is there any certain nute I should give a little extra or just up all of them a little bit. I'm using your same soil mix also if that helps

It is best to remove any excess runoff liquids from your catch trays otherwise there is a risk of problems due to runoff nutrient residues.
Thanks John I'll try that and see what happens what about putting some cal-mag is a spray bottle and spray the leaves?

I have not tried foliar feeding with my cannabis plants with a calcium and magnesium product to give you a recommendation for the strength to use.

Hi John, what's your diagnosis on this? I'm thinking cal mag but more mag

I believe that the leaf damage in the photograph is a nitrogen deficiency and and calcium deficiency with possibly a magnesium deficiency as well.

Been through my entire current grow using a complete formula of nutes (G.E.T.) but I must say I feel like I can notice a difference in growth rates due to the lack of calmag...will be getting some more and botanicare just popped up in the UK.

Funny you should say that, I've got another poorly girl which I suspect to be phosphorous
I just say that cause the leaf pic you show looks really similar to the phosphorous deficiency pic in marijuana garden saver
Lower leaves still are turning brown and some of the edges are turning up. A lot of them are pale looking but the veins are darker green but the new growth looks good. Then some of them have rust looking spots on them there's a lot going on with them. I'm giving 1/4 nutes and reg strength cal-mag temps are 75 to 77 humidity is 50 to 70 I topped and fim some of them and the new growth looks really good. Should I add more then 1 tsp of cal-mag per gal?
I've been reading up on this and it seems to be calmag the way the leaves look and all my stems are really purple witch I just noticed so should I flush the crap out of my plants with ro water then feed with 1/4 nutes and double the calmag? I read that works but wanted some more options before I do it. Feedback plz

Your leaf damage appears to be from a phosphorous deficiency, calcium deficiency and a nitrogen deficiency. I would increase the amount of calcium and magnesium to 8 milliliters per gallon and increase the nutrient strength to 1/3 strength.
