3 weeks from clone 400 mh 20" away 70-80 degrees ph 6.4 soilless mix fox farms trio im growing this super silver haze from clone this problem started about a week after i got it i had spider mites but killed them found some under a leaf with white spots on it this is a different leaf and its happening to other leafs now please give me some ideas on what could be causing this i had been going by the foxfarms feeding schedule at 1/2 strength every other watering i dont know if im supposed to go by the hydro or soil schedule since im using a soiless mix
What is your medium, and your ph like? Are you using tap water? What did you use to kill the spider mites? did you spray it with the lights on?
Sunshine mix #4 ph goes in 7.0 comes out 6.3 I use well water I let it sit for at least 24 hours and earth to e insect control with pyrethrins and canola oil active ingredients yes I sprayed t hem with the lights on
I would lower the ph a half a point if I were you.. perhaps it's a lockup because it's a bit high.. Also could have been a reaction to the spray with the lights on.. is this symptom on the new growth as well?
Its actualy on all the older leaves I took clones off of it and cut that leaf and now its on about ten leaves
Is that salt don't plants lock out because of salt build up think they do why did you put Epsom salt in there? Sent from iPhone 5
Oh it might I have never used it or looked into it lol just know salt is a no no but it might have other properties that help more than hurt Do you have a new pic of the damage Sent from iPhone 5
I agree. Add calmag and bring the Ph to about 6.2. At 7.0 you're locking out certain nutes and only spray them just before lights off to avoid sun spots. Neem oil will help protect the plants from bug infestations.
if you have being using epsom salts it shouldnt be magnesium related, id give the soil a bit of a flush with ph'd water
Ok thanks everyone ill try flushing can I ask a side question here? If im using soiless mix which foxfsrms feeding schedge do I go by
Update on the condition of my super silver haze guys. half the leaves have the brown red spots. the ones that were first affected are turning yellow, drying up, and falling off. Now the weird thing is I have another plant, this one is afghani. It was planted the same day in the same soil and getting the same nutes, yet this one is thriving. Probably my healthiest, fastest growing plant so far.
