Nitrogen toxicity from feeding too much or too often ....... or both. Autos can usually get by just fine on half to three quarters strength nutrients. Be careful with mixes containing a high percentage of peat moss, they can be too acidic for cannabis. Check the pH of your run off, this will give you the true picture of what your plant is dealing with. No point pH-ing you feed/water to 6.5 if it is coming out 5.5! Personally, I prefer a schedule of plain water/plain water/feed/plain water/plain water/feed...........it is very easy to fix a slight under feeding...........but very, very hard to rescue a burned over fed plant!

More info, I ph every water as 6.5 and in last 2 week I fed her AN voodoo,tarantula,piranha and 3 day ago was micro grow bloom + calmag + silica total 600ppm (my tap already at ~300ppm) I water every 2-3 days as picture you may see too soil little dry but it my cycle, I water after took picture. Feed schedule is water/feed/water/feed appreciate all answer. Thank you.

No diary = no information. No information = guesses. Offhand, I'd say you've overloaded her with nitrogen (be careful of calmag - it is heavy on the nitrogen as well!). Could also be a pH issue... but again, no information doesn't help us help you... Soil looks awfully dry, so it's possible also that you're not helping rid the soil of built-up nutes and salts... need to water so you have at least 10-20% runoff... So many things this could be... but those are some guesses. Start a diary... reconstruct as much as you can going back as far as you can... that way, we'll have all the information we need when problems/issues arise... Good luck...

are you allowing top 1" to dry? (or the weight of pot at that time as trigger) Can probably preempt that point a bit, but not too much. Looks like it could be frequency of watering along with a little too high of nutrient concentration. So, assuming this is a soilless/hydro grow and fertilziing each time with 10-15% or runoff (waste to drain or outside). The runoff maintains the EC of substrate. Ensure pH is not a problem. Your fertilized water and the substrate - slurry or runoff. a not on those last 2.. they are not accurate. Expect them to be a little further out from "7" than it reads. mostly likely it will be acidic.. if it reads perfect, no worries, but if it reads slightly more acidic that's what the runoff helps maintain. if it is WAY off, that's when you have concern about raising pH. i highly doubt it is alkaline given the nutes and peat-based substrate. use a nutrient ppm calculator to see what you are providing. It's as easy as a google search and typing in info off the guaranteed analysis labels that any self-respecting hydro nute line will assuredly have. if it's more than a little over 1.5EC in total, that will eventually cause toxicities in a constant fertilization context, even if the ec remains stable in substrate. It may not happen immediately, but eventually will build to visible levels not far above 1.5 and that's assuming a decent balance to diet. can happen much lower if something is out of balance. when using peatmoss, go up to 50/50 with perlite or equivalent. 70/30 is better for coco becauase it holds less water per same volume as peat does. Will make droop from watering virtually impossible unless you run water through it at decent flow rate for long periods of time, because that's what it should take to drown roots in a good substrate. 50/50 [eat/perlite is perfect for soilless/hydro growing or even a soil substrate.. o2 levels and good drainage are simple important for roots. this provides it at optimal levels based on more than just anelcdotal regurgitation, but rather real research at utah state university.
