mother fucker i now c what the half strength talk is all about. i am noticing yellow marks on the leafs of a few plant. some might be spash but others are from absorption. fuck dont think its to bad i got plants last sat transplated in moist soil and lightly waterd. i waterd again on mon with foxfarm nutes at about 3/4 strength maybe a little stronger but not much. again watered them wed and on this day after watering i noticed my first little yellow spot. thur a few more plants had a spot on there leafs 3 are on lower leafs that had been cut by the club 1 spot on a middle leaf. the other 4 plants look very strong with no spots. cant get a clear pic at the momment but i will continue to try. i am only going to water every three days and i think my next water very light nutes if any any suggetions please post
Yuppers... I'm a 1/4 strength guy, myself.
Foxfarm nutes are very strong, very acidic. Nutrient solutions made with any brand should be checked for pH and adjusted back to 6-7 with baking soda or pH-Up.
This has to be the biggest ongoing folly in the whole MJ growing world -- ppl adding nutes that the plant does not want or need.
Over time I've been able to really suss out who the really good growers are on RIU. Their approaches? Generally 1/4 strength added every TWO WEEKS. A lot of folks on here add nutes every other WATERING... Well, what the top growers mean when they say that is "every other week".
Why? Cause they water heavily enough that their watering lasts a whole week. Then they let the pot dry for a whole week and water again, this time with nutes. So, it's an every-other-week deal.
Ppl who grow successfully on heavy nute schedules do so in spite of the shit, not because of it.
