New strain Meringue

02/10/2019: hi guys i'm having problems for about 4/6 days: i'll explain I gave the nutrients as usual, and the morning of the next day i found the leaves around some buds, burned and softened !, i thought it was the nutrients, but reflecting well and looking at the leaves that have the tip pointing downwards, I thought, even in a heat wave that did all of this inside my tent, but the fact that out of 3 plants only one suffered so, I Give up some doubts, if you have any opinion I would be grateful! good 4:20; all this 2 weeks from the harvest :(😵
