Droopy leaves, some leaves yellow with brown spots
She has droopy leaves. There are leaves with brown places, and some leaves in the middle of canopy turned yellow. At last she started preflower in week 8(auto) but compared to another girls she is very slow with pistils. Some leaves are curling up.Maybe too much light?

What could it be?
I'm a relatively new grower and I don't have a diary setup yet. I know it's hard to diagnose a problem when there is no diary, sorry! They were good until they started to yellow. They are in their 5 to 6 weeks of flowering. Some are good some are yellow and I feed them the same.

Triple question: -Why are bottom leaves yellowing this early? -Explain 'What is this!?' picture -Is it normal that when they transition to flowering stage leaves' stems curl down like in Day 56, Rebel (II)?

Manchas amarillas
Le han aparecido unas manchas amarillas en las hojas inferiores que no se muy bien lo que es. Tambien acaban de aparecer los 1° pistilos y no se si tendra algo que ver, me podrían ayudar? Carencia? Sobrefertilización? Se han quemado por el sol directo? Normalidad? Gracias

Leaves' apex yellow/white
First grow here. This is an auto strain 20/4. pH is on point, I'm using growing nutes once a week (I water around twice a week). Only the young leaves have this. What is the cause according to you guys ? Is it a serious problem ? Thank you all :)

New growth and top leaves have some discoloration. Could it be light related, or maybe a zinc deficiency?
She has been flowering for about a week now and showing some pale spots. At the start of flower I turned the light up from 200w to 300w. Light is currently at about 20" from the canopy. Plants seem healthy otherwise, should I be concerned?

Leaves Turning Yellow - RQS Watermelon Auto
Hi GrowCommunity! I am currently growing a RQS Watermelon Auto. The plant is in week six and started flowering two weeks back. I did some LST which the plant handled quite well. I am seeing leaves turning yellow starting from the inside. Is it missing nitrogen? Thx in advance..

Small yellow spots
I have small yellow spots on leaves. I want to say it starts at tips and travels down. I moved light away and it seemingly gotten better. I moved tents for bigger space and it might have returned.

High TDS and low ph runoff - Lockout? deficiency?
Struggling with some bad soil (beginners mistake). I water with dechlorinated tap water at around ph 7.4 and 400ppm (not feeding yet). But runoff ph is 6 and around 1000 ppm. Am I dealing with a N-lockout? why such a ph difference and high TDS value?
