hey this is my 2nd indoor grow I have 5 others of the same strain in the same medium and pots. they are about 3 weeks flowering atm this plant for a while the last couple of weeks all the shoots were not opening up like they normally do when you start to flower It looked like strunting cause they pretty much just refused to open for a couple weeks so i transplanted to a bigger pot now they are opening up like normal but i went to water today and i noticed just on this single plant the edges of a lot of leaves were discolored , btw the strain is nirvana white widow and all my other plants are in the same conditions , fertilizer and light that this one is in please take a look at the pic and tell me what you think thx
