Need advice, please

[MysticMimi]

Hello everyone!

I’m working on my second grow, the first of which was a total fiasco. Now that I have found the GWE community, this grow is going much better!
I’m growing 4 autos indoors: Gorilla Glue, Tangerine Dream, White Widow and Critical Purple. Using LST method with pipe cleaners.

Noticing some leaf discoloration that started at the bottom. Just fed some cal mag last week (1 tsp/gallon). I’m on well water - I live in the Shenandoah Valley, which is a Karst topography, and am surprised that I would have a cal mag deficiency. The PH runs about 7.5, so I use the PH down to get it to 6.5. However, when I use my bloom nutes once a week, the PH drops to 6.5, so I don’t have to use the down.

Then I noticed some leaf tip burn on the 2 tallest girls, the WW and CP. Thinking it was light stress, so I lowered them.

My question is this: How often should I administer the cal mag, if you think that is problem? Is it advisable to cut the affected leaves off of an auto? Am I right thinking the leaf tips are a result of light stress?

Any advice, tips, pointers would surely be appreciated. I hope to pay it forward when I gain more confidence!
Thanks 🙏

PS: I’m trying to figure out how to do a signature line where all my pertinents show automatically so I don’t have to type it each time.

The issue I see is what looks to be a nitrogen deficiency on your CP. need more Info to help with the rest of your issues but there’s definitely a nitrogen issue, the tips of the leaves curl under like that says too much nitrogen.

I think your issue is overwatering. I’m seeing no deficiencies. Slightly burnt tips but you’ll have that sometimes, nothing major.

temps, humidity good? overwatering maybe...do the pots have good drainage and how are you watering them.

Hey @MisticMimi to edit your signature there's a drop down arrow next to your username top RH corner. Click User Settings, click Account, scroll down to Conversation Detail Options, click Edit Post Signature. Others will weigh in on the plant but overwatering is easy to do as you probably already know. What's your normal feed/water schedule? If it's over watered you'll want to let the pot dry out.

Thank you, good to know!

I try not to water until pots are dry, but I need to make sure from here on out! Thanks for your input!

I water with a pitcher when the pot feels light. Temp about 75 with 50% RH. Lots of drainage on 3 gal plastic pots, but I did order some fabric pots for next grow! I def need to make sure they are totally dry before watering! Thanks for your thoughts!

Thank you so much! 🥰

I’m gonna check it out! Thanks so much! 🙏

at 75F is that daytime or night? at that temp the plastic pots won't dry out much soo be careful not to water too often. at that temp i'd say every 3-4 days
