Need help - leaves turning yellow and brown- week 7 of flowering

I'm not sure if this is normal or not, but I'm seeing a lot of leaf discoloration over the past few weeks. This past 5 days has been super hot & Temps spiked up to 92 degrees.

This is an auto... I'm thinking it likely has another 2-3 weeks in flower?

I haven't used any nutes last 2 weeks. Just water. 20200425_112755.jpg20200425_112713.jpg

How long has there been leaf discoloration? If its going from the bottom up until they fall off, likely screaming for nutrients. I dunno if I would have started giving straight water two weeks ago if there are 3 weeks left. Usually that is something you do right before harvest if you want to at all.

Fact that you had 90 degree heat just made things worse imo.

I thought I accidentally overfed. So wanted to cut back to water to help flush it out. I guess next watering I should go back to feeding? I'm using SHINE from Hydroponic Research. They claim it can be used until a few days before harvest.

Does it look about a month away? Serious question... Because I'm not sure

Whether overfed or underfed depends on how frequent you feed, amount of nutrients fed and the medium they are in. Some mediums need a lot of supplemental food, others not so much. Depends on your schedule but going without any nutrients for two weeks in the middle of flower is a bad idea.

You're in a tough spot. I'd suggest taking a look at the trichs to see what proportion of clear/cloudy/amber, hard to tell off that photo. When mostly cloudy with some amber I chop.

It's hard examining anything under these leds. Everything looks reddish.

Thanks. Learning as I go!

If you have been flushing for 2 weeks that's why its discolored..??? You are flushing the plant the result is the green fading out thats the entire point remove nitrogen and chlorophyll...just dont flush until sugar leaves turn yellow and buds..
