yellow leaves

I3LUEYEDEVILstarted grow question 7y ago

A few days to flower...some lower fan leaves have yellowed and I removed them. How do I ascertain whether an off pH, heat stress , or nutrient issue is the cause. What is my best course of measure to correct this issue?

Ph your water when you feed helps and a nutrient wand to make sure you know the ec of the water your feeding. Yellow leafs at the bottom probably isn’t too much of a worry they die off from lack of light in the flower stage normally .

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

The most common yellow leave will be found on the terminal stage of flower because plant will power up for flower produce rather leave grown. Leaves are most of the time a reservoir of H2O nutrients and minerals. Yellow leaves can apear on you plant at some point of grow?

Lockout or not enough nutrients ?Hi grow fam, I’m starting to see some slight discolouration on a couple of leaves. I’m wondering if it’s being nutrient deprived or locked out. I am leaning on the side of caution by using GH’s light feed schedule. No signs of root rot inside the bucket
