Plants Turning Purple With White Tips

View attachment 1405365

Hello the tips are turning white with some burning and the leaf is purplish on the outside it is happening on the new growth to.

Do you guys think its a sever case of lack of nitrogen? I've been feeding it Crosby's fancy molasses and Virogo nutrients with the npk of 15-30-15 I flushed it last night and I'm going to maybe get some nutrients with a high nitrogen ratio. Do you think the white tips could be caused by to much potassium or something?

Temperature during the day is 27-30c and light off it could go to 17c

The roots are growing out the bottom of the pot and its just reaching its second node.

Do you think I should just water with plain water or get some nutrients with nitrogen or something, I'm fairly sure its going enough potassium because the molasses has potassium, calcium and magnesium.

Lights are 18/6

I'm open to anyone's comment or questions

what week are they in? flower or veg, and can you show me size of plant or about how big it is

Week 2 and 2 days from cutting from mother, Vegging hours are 18/6 and no bigger then 4 inchs

oh shes just a baby. its nuit burn, give him 6.2 ph balanced water flush for a couple feeds then start nuit feed again when you see new health growth but give her light feeds 1/2 tbs(nuit) per gallon. when she gets older and has better root growth bumb it up to 1tbs(nuit) per gallon

Thanks for the assistance i'll be sure to do so

also I should mention that there's like 6-7 roots showing out the bottom of the pot

Thank you for the post I am having the same exact problem and was just trying to figure it out thanx for the help

bro once you flush jus give them water for a week then start the nuets at 1/4 the sugested amountthen as your plant gets bigger up the amount.you dont have to really give them that much cal in veg mostly n....gl bro

if roots are showing out of the bottom then its definitely time to transplant into a bigger pot cause it those roots arent in the soil they arent going to be getting nutrients

that plant can stay in that pot for now and for another 2-3 weeks. the purple is not burn. give it a lime drench. 1tsp/gal water and you will be right as rain
