Well these past four days were miserable. I kept the same watering routine, but on Friday temps hit 114 degrees which I thought it almost killed two plant. I took it inside for two days away from the heat and I watered it. It seems to have recovered but still has plenty of leaves that are sunburn which I’m not plucky out as they die. The plant is still growing with no signs of it wanting to start flowering. If it doesn’t auto flower then I will keep it in veg until it recovers from the sunburn it got.
That may not be burned from the sun. Is the 5 tsp per gallon correct? If so, dial back your nutrients to 50% of what the manufacturer states for their product. Flush before doing so to get rid of all excess nutrients in the soil.
@Tophat, it's sun burn there was one day that temps reach 115 and it was out in the sun. Since then the leaves dried out and shriveled up. If it was nute burn then all the leaves would have the same symptoms especially the lower leaves. The plant only gets 7ml of each nute once a week which is the max. The rest of the week I just add water and make sure plenty of water runs off.
We both my be correct in some way. If it's extreme heat we could dial the nutes back, protect her from the scorching sun with some shaded area that still receives light and see if she will recover. She is having to work extra hard now to compensate for the lost time since she is an Auto. Plus if her roots get too hot, she will run into root zone issues that may not be able to get fixed in enough time for harvest. I hope she recovers for ya!!
