Purple Kush

First i am not seeing any kind of veg nutrients in your line. And no to your question always start out quarter strength for seedlings. Then gradually raise to half strength. If you are seeing signs of deficiency then only then start raising more. Hope this help

It looks more like a phosphorus or potassium deficiency or both but the rest of your leaves look great in your photos. It could be an old deficiency that just became more pronounced because it was an older fan leaf. You are adding quite a bit of cal/mag I would lower it to 3 ml per gallon excess calcium can cause potassium lock out. Don't forget some of your other products have calcium in them already. Sensi Cal/Mag extra is a chelated product using EDTA which allows the roots to rapidly absorb the nutrients. Signs of phosphorus are dark green almost blue-ish coloration of the leaves with brown necrotic spots at the edges. It's also wise not to mix different companies nutrients and try to use their specific nutrient feeding charts if possible. Hope this helps.👍

Hello sister😊 The only real infallible technique to know when to harvest is to look at the trichomes of your plant😉 For this system, we would need a magnifying glass that enlarges at least ten times, but the most appropriate magnifiers or microscopes are 50x. The trichomes of the plant are observed to see if they have reached optimum maturity. It is when they have completely reached a kind of mushroom shape and at least half of them have already passed from translucent to milky and a low rate of these are amber that the time will come to pick up. I love them 30% amber but it's just a matter of taste 😎 It is certainly the most reliable of all systems to determine the optimal point for harvesting cannabis, but the ideal is to combine them so that you can get the best conclusions. Once we have analyzed all the factors and decided to cut, it will have to be done when the relative humidity is as low as possible to prevent the same moisture remaining inside the head and can cause mold. Then we will cut, whether from the whole plant or by branches, then will come the time to manicure cannabis. The manicure is to cut the largest leaves of the plant and the leaves without resin, then will come drying in a dark and ventilated place.👍 Good luck for your grow 🌱 May the force be with you💪
