Hi guys. Why do leaf tips dry on my plant and yellow dots appear on the top leaves? They bloom for about ~30 days. I use AN Ph perfect Sensi Coco at 4ml/l. In: ~1500ppm, Out: 1750ppm, 5.7ph. Thanks.

Triple-leaf Speedy Chile: what is growing there? Why becoming yellow?
My triple-leaf Speedy Chile (see also week comment for more info): 1. The 3 cotyledons have become yellow. I also see on lower leaves slightly some yellow tips. Nutrient deficiency? Underwatering? 2. What are the small leaves coming out of soil. Another plant? Should I remove?

Yellow lines on 2 leaves
Any clue what this is? About to be week 6 and in flower. I'm thinking the start of nute burn? I gave it bloom boost in the last 3 waterings in less and less amounts. let the soil get very dry before watering with plain 6.2 pH water. Any input is appreciated

You are a SATIVA North Shore Maui! You grow tall like the sky! Strong like mountain! You are not descended from short plant!
Currently overthinking this plant's development. Pep talk not working. It is a sativa but the shortest plant in my garden. Maybe just needs a trim? The yellow is a concern too. I haven't dealt with a plant this bushy before so not sure if it needs help or not.

Yellowing leaves, some twisting, early in veg?
Could anyone help me diagnose this plant. Idk if it’s nitro defic., heat stress, or overwatering or all 3. Temps during the day have been getting up around 86-88 daytime and only down to maybe 74 at night in the tent. I try to let the top of the soil dry out when watering as well

Lock out or lack of nutrients ?
I am having trouble identifying if this is a lockout or lack of nutrients. I was told to stop flora micro. I have been giving 50% strength of what the bottle suggests. My other plant same tent just had a lockout and I flushed.

What to do? → BF Runtz Auto - Day 42 - RH70, 80F in BioBizz Light Soil
On my last post, I was advised I have N tox, so I watered w/o BioGrow, just BioBloom and it's gotten much worse. The runoff EC was 1.5 (watered with 0.8, runoff pH was okay), so I’m guessing it's salt buildup. I plan to flush when this watering dries out—any thoughts?
