these spots on the new leaves, they were also born in an ugly way I'm using plant prod 7-11-7 + calcium nitrate 700ppm, I was using low dose because I had a problem with excess N, now i'm using 1.15g PP + 0.7 g CN / L i Hope this help my plants

Hello there, I'm from brazil as well but let keep things in english. Looks like I think you should use something like 0.8 g Plant Prod 0.4 g NC 0.2 Sulf. Mag. It will give you 700~750 ppm, here i add some water to have 600 ppm*. Im in a vegetative stage with 64 days of life with this recipe. * Maybe you should use lower ppm, but you have to give a try and look how the genetic feels. If you need anything you can talk with me here or in Instagram (same nickname)

Just buy some proper, cannabis specific nutrients! Why go to all the troulble, effort and expense of setting up a grow space then use a mixture of generic garden fertilizers designed for brussel sprouts? Do this and all your problems should go away and you will then harvest decent flowers. Everything you need is on EBay! Recommendations?.... Bio Vega and Bio Flores made by Bio Canna, Organic Grow and Organic Bloom made by B.A.C., both these lines are one bottle for veg and one bottle for flowering.... Otherwise... General Hydroponics (GHE) products, Canna products, Plagron products, Hesi products, Top Crop products, which are all available online. Mandala Seeds have an excellent "grow guides" section on their website, it has a lot of great information for (European) growers and this may help you to get a better harvest.

It's a potassium deficiency I believe. Too much phosphorus in your feed. Vegging npk ratio 3-1-2, flowering npk ratio 1-2-3. I feel your feed is way off this ratio. Which will cause problems.

700ppm is a safe overall totall (assumes hanna 500-scale or calculated from guaranteed analysis labels) TDS pens convert EC to ppm with a simple calculation. it does not actually measure parts per anything. it is converting a measurement of electrical conductivity and dependin on the product you buy it'll give a different ppm for the same EC, which is teh apples to apples measurement. 1.4 EC should be fine, but the ratio of nutrients is equally important.. i'm going to assume the "pp" is dry amendments? if not my calculations may be off a bit due to specific gravity. 1.15g pp and .7g 15-0-0 cal nitrate results in: oh, is that grams per gallong or grams per liter... PPM N 50 * 3.785 = 185 P 15 *3.785 = 55 K 18 *3.785 = 67 Ca 33 *3.785 =126 i assume the 7-11-7 has other stuff beyond npk, but you can see this is an extremely low feed if grams per gallong and definitely way too high N if g/liter... Also really low on potassium, that should be up near 200ppm. Ca should be okay.. unless you have very hard water with lots of calcium in it already.. so in some contexts that could be too much. assuming that is grams per liter and no other products add N, i'm going to guesstimate based on how these 2 products reach 120-140 ppm N (120 is safer place to start, then observe and boost if needed. .33grams per liter of cal nitrate with 1.15g/l of pp would bring you to 130ppm N... but your balance is out of whack with these options. You need more potassium. 55ppm P is great. by dropping cal nitrate so far you now need more calcium from another source... Mg and S are equally important and should be 85+ and 100+, respectively. you can't get there with these 2 products. N/P/K 120-140 45-60 180-210 Ca/Mg/S 100+ 85+ 100+ So the last three will vary due to water used and what comes in it. if RO, probably need a bit more than what is listed for those. With NPK it's mostly the N that needs to be manipulated. This is a good ratio fo nutes to use and scale in proportion to 1.3-1.5EC based on plant observation unless you see a specific symptom that says otherwise. use an online ppm calculator. there is one on manic botanix.

Well, good luck to you, mate! Without a diary, I can't comment on your plan...
