Leaves. Color - Mottling grow question by WooderIce

WooderIce started grow question 4 years ago

Can someone look at my newest pics? 1 of 4 plants (shortest of the 4, so its not light burn) has about 6-8 fan leaves like pics. Happened 36hrs after i did a big flush, that brought my ph down around 6.7. I think its either too much nutes, or lacking phosphorus. Help!

Don't search too long : it is a PH issue. 1st last week you PH was 7.6 in soil which is way too high , then you flush your medium and down your PH to 6.7 so almost 1 ph unit less than last week : This PH fluctuation is too high , you should have low your PH gradually than low it like that. The harm is done, just stick to that ph for your next feeding and wait for recovery :blush::v::skin-tone-3:

How's the overall air circulation? I like to move my thermo/RH meter to diff areas of my grow space. Check to see if the lady in question may be in a "hot spot".
Remember consistency when dealing with pH. I adjust almost daily to get good numbers by adding small amnts.
Spots/curved leaves- you got a great garden either way.

Hi @WooderIce! Are these symptoms appearing only on the upper (young) leaves? If the answer is yes, you might have a light burn, in this case you should increase your lamp-to-plant distance. If you're confident it's not your light, then it's probably a potassium (K) deficiency. This could have been caused by your recent flush (plus you flushed with the wrong pH). Give it some K in her next feedings and try to stick to the optimal pH range for soil, which is around ~6.2. Buds are far from being ready and they will need some more Potassium to fully expand. Hope this will help, keep us updated and happy growing :facepunch:
