Forbidden runtz excess or deficiency problems autoflower
BAD WEEK! need some help here guys.. Brown / rust spots started to appear on the tips and slowly started yellowing leaves. Im following the master advanced nutrients chart and watering 2 times a week. Last week feed was 20 litres R/O water 80ml bloom A 80ml bloom B 40ml of every additive on the chart 20ml cal meg 30ml phup PH adjusted 6.50 After i started noticing the brown spots / leaves curlin up and stunted growth i skipped a feed and flushed with plain R/O water used 30 litres for 4 auto plants. Yesterday i watered again but cut the nutes in half. 20 litres R/O water 40ml bloom A 40ml bloom B 20ml of every additive on the chart 20ml cal meg 20ml phup PH adjusted 6.50 I still don't know what the problem is, if it is a excess of something or a deficiency..Looks like a cal meg deficiency but ive beed using cal meg since the beginning. Maybe i have excess nutes in the soil and resulted in nutrients lockout of cal meg or something else? since i water twice weekly should i water with nutes always ? The master advanced nutrients chart still sometimes confuses me. Please any help will be appreciated

Strange leaf shape, who has encountered this and what came out as a result?
1. Am I right that it was just overwatering? 2. Who has experienced the same thing? 3. What are the chances of growing a healthy plant? I appreciate all the responses, this is very important to me, thank you!

Burnt tips and yellowing leaves
About two week ago, lower leaves started yellowing, and I saw burn leave tips, so I suspected nutrient burn. I only watered with tap 6.5 pHed water since, but the burnt tips and yellowing are getting worse continuously. At least 3 largest lower leaves died off over the period.

My Green Poison leaf tips are burning not sure what it cld be. I was thinking magnesium deficiency jus off the simple fact that I have been using distilled water which doesn’t have any nutes the plant need (now using de chlorinated tap water) or is it heat stress or nutrient burn ?? I know my tent can get a little hot because of where I’m at but it’s somewhat under control. But if u have idea or suggestions for my Green Poison I’d appreciate it .

Yellow tips of leafs …
Overfeeding? Yellow tips starting on top of the plant … should flush or just wait and reduce the feeding next watering? I‘m entering the pre-flowering stage and would normally start to add bio bloom and top max with the next watering …
