Please help, yellow spots, dry leaves.

Schwierig zu sagen ohne viel Informationen. Aber für mich sehen die Pflanzen leicht überdüngt aus. Die Blätter rollen sich leicht auf. Weshalb düngst du grow und Bloom zusammen? Ist grow nicht für die wachstumsphase und bloom für die Blüte?

Absolutely no problem at all. The color is a perfect color and porbably you shoul worry most if you have a full dark green that would indicate a strong amount of nitrogen on flowering stage, so that situation probably would be a worst situation that see the wqays that your present grow reaveals. At the seven week the most lighter green on your grow indicates precisely wht should come next that is the end of the cycle and it is perfectly normal from now on to have a much more numeber of yellowish leafs. On the rest your grow seems to me pretty solid. My opinion is not giving on a weekly basis CalMag nutrients ...normally the Cal Mag is usec when you have blocking of nutrients or "soft" waters - normally water with low amounts of calcium. On the present week you shoul try to increasingly gave much more PH (phosphorous and potassium compounds). With long practice i do not use anymore the PK solutions that the nutrient brands have. Lately i combine two products - organically Gold Green PK 21-30 and from Cultivers (Amazon) they have a powder composed by leonadite (with heavy fulvic acids amount and a stron potassium oxide compound. Using three times a week the soltuion of Cultivers - Fattening and Mature (for potassium oxide and fulvic acids to integrate faster the potassium salts available on the grow, and the organic Gold Green PK 21-30, we link a heavy amount of phosporous....and doing that solution and irrigate 3 times a week and other three days only plain water with no chlorine, you will have amazing buds and a outstanding grow,

What Roberts said. Start a diary........more information = much better answers. Always post pictures taken under "normal" white light, pictures taken under grow lights make it impossible to see details.

If you are only giving 1 l of water daily and are adding nutrition without getting run off then your overall problem is a salt build up. When adding nutrition, you need run off to rinse out old nutrition salts left behind.

to much nutes.. flush the plant with phd water should do the trick
