shifted to flower 5 days ago. random leaves turning yellow. veins change even with leaves. stems turn purple ish. most are bottoms.
Seems like a nitrogen deficiency. You giving nutrients?
using fox farm soil. with 1 cup guano, 2 cups worm casting, 1/2 cup azomite, 1/2cup dolomite plus lime and 3 tablespoons mycorrhizal. 5 gallon smart pot. half gallon water every other day with general hydroponics 2ml of flora grow, 2ml flora micro and 3 ml flora loom. ph-6.2 after mix. temp. 72ish always. humidity 55ish. LED viper spectra 11 on 13 off. alot of leaf movement with supplemental ascolating fan.
You checking ph levels from your run-off when you water?
no. should I have run off? why would I want nuts to be wasted? I’m new to this. listening
You definitely will want to check your run-off pH & tds. You’re not wasting nutes by watering to run-off.
In my opinion, testing ph and ppm is absolutely key to a consistently successful grow! Once your soil, water, and feedings ph range goes above or below the recommended range, you start getting nutrient lockouts and can even become toxic to plants. If I were you, I quickly get the instruments you need for testing. Go on YouTube and get some quick lessons on optimal ph ranges and ppm levels for different stages of growth. Here’s some useful info to get you started. But only the basics, gotta learn all you can! And take notes.
I really appreciate all the feedback. my pH and TDS meters will be here Wed. today I purchased 15 gallons of RO water. flushed plant. will try to het her recovered. 4 more fan leaves yellow today. I’ll find and watch that video. thanks for the help.
Anytime, just tag me or anyone if you have any questions. Put an @ before their name to tag a particular person. Example; @whiskeysmoke1965
received my pH and TDS meter today. I had saved some runoff from other day. holy crap it wasTDS 263, pH 6.4. Do you suggest when it dries, do a watering test before pour and test runoff. 5 gallon fabric pot. thinking 1 gallon of water.
General rule of thumb is water to 20% runoff. 6.4 is a good ph. They are starving though! Gotta give nutes ph’d to the recommended range. How long have they been in veg?
Never mind, give them around 800 ppm of nutrients. You just started flowering.
Another general rule of thumb is not to let the Ppm’s drop below 300. Unless you’re doing a flush.
Here’s another piece of essential information.
here is an update. no more yellow leaves. watered again today. pH 6.1 TDS 742, Runoff pH 6.7 TDS 1342
Looking spectacular! Nice job! A little research goes a long way. Proud of you!
