@Waira @AutoLowRyder 2 days ago noticed my bigger fan leaves are gettinf small black looking spots and yellowing and browning. So last night did a small flush then added 1/8 str veg nutes, 1/4 str bloom, and 1/8str cal mag. Temps 72 degrees. Humidity 45 percent. feeding 6.4 ph. 39 days old. Been flowering for about 9 days now. Have alternated feed/water/feed.

You should be using full strength bloom nutes now and at least 1tsp per gal cal/mag every other watering.Also try and get your temps up closer to upper seventies if you can.

I can try. Half strength nutrients burnt these same 2 strains last grow. Getting temp up shouldn't be a problem. My plants dont seem to like more than half tsp of cal mag a watering either. But i will try it. alot of grows I see nobody is ever using full strength nutrients but can hurt to try. It's just a plant lol. Worst case it dies.

What nutes are you using and what are the npk numbers and recommended dosage?Cal/mag is very important for the uptake of nutrients and it's hard to give to much cal/mag.

 

[Boognelson87]

Botanicare cal/mag. My veg nutes are 6-4-4 and bloom is 1-2-2.

I'm actually giving them over half strength dose now. Says 2-4ml and I give 2.5. I can try 4 this feeding with a little more cal mag. Cant hurt to try.
