Looks like calcium deficiency starting on lower part of the leaves. .1ml seems low but I'm not sure the source that you are using. 1ml per litre of water should help correct this in 7-10 days.

Don't bother you , Hybrids Powder is working perfectly when combined to calcium from GreenHouse and PK Boost from Grennhouse too , they are designed to be mixed together . I've done it and it's cheaper than anything else , easier than anything else and all the mixing ratio are on the packages. With this trio no need anything else

Hi there! I think you should be fine! Just mix all powder nutrients to water first before adding liquid nutes. Sometimes when you add powder nutes to nutrient water there might be some chemical reactions and some nutes will not be usable to plant anymore cos they combine with other. If you mix powder to water first then liquid I think its safe to do! I use pure salts and some bottle nutes myself and no problem when done correctly! 👌🏿

Hi there.. that depends on your environment and how your plant can handle it.. if you slightly under-feed with your regular nutrients, then you can try adding the booster and raise the total EC a little. If your plant is already being fed perfectly, or on the higher side, the extra EC might be too much for her to handle. My white haze grow has very very lightly burnt tips, because of exactly that.. she's fine with 1.1 to 1.2 mS at this point (i grow her in a hydro-DWC setup and measure EC of the nutrient solution daily), but when i change the reservoir once a week, and add the boosters, she gets around 1.4 mS, which is too much.. that's just in for a day, as following that, i top up without the booster and over the course of a few days she drifts down again. If i followed the instructions on the back of all my nutrients blindly, she'd get an EC of 2.9, which she could never handle in this environment (under a single 50-walldrawn-watt COB), and i prefer my plants rather to be healthy than overfed. happy growing!
