Nute lockout? Or def.?
RedBunnystarted grow question 3 years ago
Looked like light burn, but light is far away now and its still happening. It is happening worse on girl, which is longer in flowering mode. I accidentely watered with pH 6 from beggining, but last week with 6.5. Every watering - 2 ml/l Plagron Alga Bloom, 0.1 ml/l Calmag.

To continue my previous answer: the nutrient that probably is too much and is creating the nut burn is nitrogen.

Hey mate, I really think it's nutrient excess. I have the same problem on my running cycle and same, the light is very far from my babies.
Just give them clean water and make sure to correct the PH to 6.5.
It's not 100% because you gave them too much fert, but probably the PH at 6 let this plant suck a lot of the nutrients that marijuana can "suck from PH 6 waters" so you have an excess now.
I'm trying to get rid of mine yellow tips since weeks, they do not go away. Today after 2 week I will give a bit of bloom fert to 3 plants and plain water the the others, let's see what happen.

Could be ph or cal mag deficiency. If its just the top leaves id say cal mag. They need extra during first few weeks of flower

Help with burned leaf tipsThe tips of some of the leaves have begun to dry, curl, and look to be dying (see pics). I think it's some sort of nutrient burn, but I'm unsure. I water every other day w/ a solution of Miracle-Gro 24-8-16 at 50% recommended concentration. Used distilled H2O last 2 waterings.
