Looks like the start of a pH lockout due to much nitrogen. Get the soil ph back in check and dial back on the Nutrients. Always water to about 20% runoff. 🤘😤

Nutrient burn/deficiencies/feeding
Having difficulties with a few of my plants, I didn’t add any nutrients until they were close to 30 days old. And then only cal-mag at what I thought were low doses. One of mine has lost almost all leaves. What would you guys recommend moving forward? I have almost all fox farms

Lockout or deficiency?
I have an issue with a girl. Newbie alert. I feel it’s either calcium def or nut lockout. I fed with 1/2 rec BAC grow feed and it didn’t get better, so 2 days after I gave a flush of fresh water. Now it’s really trying to grow, it’s kicking out new leaves but it’s stunted

Lower two sets of fan leaves have gone yellow, leaves on internodes in between haven't changed colour. Not sure what's causing this. Nutes? (3-4 more weeks of time released nutes in soil) Too much water? Did water a bit extra because I wasn't going to be home for a couple of days

Brown leaves and red stems. Is this a calcium deficiency ?
I had an iron toxicity recently that may explain the brown parts but it may look like calcium deficiency. There are many red stems too but it maybe something else like the bad Ph and overfeeding from the previous month. What do you think ? Thanks !!

Does yellow leaves with red tips mean my plants need more nutrients or less? Jacks 3 2 1 on Auto
Week 8 (flower) top leaf tips are reddish and the leaves are more yellow than green. Does this mean that my plants need more nutrition? I am using Jacks 3 2 1 for two autos and using it at 65% strength (650PPM / 1.2EC). Should I goto 100% at 990PPM / 1.9EC or 50% to 550PPM/1EC

Deficiency or Burn?
All these girls in manure compost/perlite mix. Healthy through veg with minor Magnesium deficiency in the beginning. Been feeding 3ml/gal calmag occasionally, and 1/2 cup banana tea I made 1-2x a week. Waterings have been at 6.5, just lowered to 6.2. About 1/4 gal/plant 1-2 days.
